|
PRESSURIZED CONTAINER GEOMETRY: |
94 |
|
Pressurized container geometry has been updated: top container TSPH |
95 |
|
now has been placed at the maximum distance, quoted in the ICD, |
96 |
|
from S1: 5cm. This distance corresponds to the maximum one in |
97 |
|
flight due to the cover deformation due to the internal |
98 |
|
pressure. Three thermal cover layers (nylon6, mylar and aluminium, |
99 |
|
respectively in the new volumes COV1, COV2 and COV3) have been |
100 |
|
added to the top container. |
101 |
|
|
102 |
|
NEW MATERIALS AND TRACKING MEDIA: |
103 |
|
|
104 |
|
Two new materials have been implemented: AMg6M mixture for volume |
105 |
|
TSPH, and Nylon6 mixture for volume COV1. New tracking medium have |
106 |
|
been added for Nylon6 Mixture (TNYL), AMg6M Mixture (TAMG) and Iron |
107 |
|
(TIRO). |
108 |
|
|
109 |
|
TOF GEOMETRY: |
110 |
|
TOF geometry has been updated: Scintillators positions in the |
111 |
|
GPAMELA reference system have been corrected shifting all |
112 |
|
scintillator paddle by 23 microns. |
113 |
|
|
114 |
|
TRACK NUMBER RECORDED FOR TOF: |
115 |
|
The TOF structure now register the stack number into the HIT |
116 |
|
structure. In GUSTEP the stack number is tested, if is greater than |
117 |
|
0, i.e. the particle is not the primary, the particle number is set |
118 |
|
to 1000+IPART and passed to GPUTOF. Accordingly, now IPARTOF |
119 |
|
variable can assume 2000 values instead of 100. |
120 |
|
|
121 |
|
POWER LAW SPECTRA GENERATION: |
122 |
|
PLAW datacard parameters have been increased to 4. The meaning of |
123 |
|
the 4th parameter is: extract random kinetic energy if PLAW(4)<0., |
124 |
|
or extract random momentum if PLAW(4)>=0.. |
125 |
|
|
126 |
|
Sept 2007, Bari |
127 |
|
|
128 |
|
POWER LAW SPECTRA GENERATION: |
129 |
|
It is now possible to select a power law spectra. Using the |
130 |
|
datacard: PLAW, is possible to pass the spectral index and the |
131 |
|
kinetic energy range. In PAWL(1) the user can pass the signed power |
132 |
|
law index, i.e. PAWL -2.5, will generate a power law spectrum |
133 |
|
according to exp(-2.5). Please note that the range is in kinetic |
134 |
|
energy. In gukine the generated particle charateristics will be |
135 |
|
retrived and the mass calculated from this infos. The KINE data |
136 |
|
card assigned momentum will be overriden as well. |
137 |
|
|
138 |
|
PATHLENGHT CALCULATION MODIFIED IN TOF: |
139 |
|
The pathlength calulation saved in the TOF hit structure has now |
140 |
|
been modified. Insted of the pathlenght inside each paddle the |
141 |
|
average pathlenght from the generation vertex to the hit in the |
142 |
|
paddle, is saved. In this way it will be possible to calculate the |
143 |
|
beta using this variable. |
144 |
|
|
145 |
|
ERROR IN MATERIAL ASSIGNMENT FOR NEUTRON DETECTOR: |
146 |
|
The material assigned to the NDTU volume was wrong. It was |
147 |
|
scintillator, IRON has been asigned now. |
148 |
|
|
149 |
|
March 2007, Bari |
150 |
|
|
151 |
|
CALO GEOMETRY: |
152 |
|
An error was found in the original document describing PAMELA |
153 |
|
geometry. The shift along X axis of the X view planes are swapped, |
154 |
|
i.e. they don't start with X=+0.05 but with X=-0.05. The sequence |
155 |
|
is: 0.05m -0.05, 0.05, -0.05 and so on. |
156 |
|
|
157 |
|
MAKEFILE FIXED: |
158 |
|
Option -fdebug_kludge has been discharged |
159 |
|
|
160 |
|
GASATT WRNING FIXED: |
161 |
|
There was a warning message from a graphic routine. The GSATT calls has been commented out. |

166 |
|
CARD GEOMETRY: |
167 |
|
Positions, dimensions and quotes have been updated. Indeed, the aluminium table |
168 |
|
under S1, legs included, and the magnetic screen between the CARD and S2 have |
169 |
|
been added. |

|
176 |
|
S4 GEOMETRY UPDATED: |
177 |
|
The x and y dimensions have been corrected because they were wrong. |
178 |
|
A container of aluminum has been added having walls of thickness equal |
179 |
|
to 0.1 cm. |
180 |
|
|
181 |
|
TOF POSITIONS DEFINITELY UPDATED: |
182 |
|
S2 and S1 have been positioned again, after the simulation of the top plate. |
183 |
|
Before now, the positions were put ad hoc based on the positions given by |
184 |
|
Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA |
185 |
|
sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and |
186 |
|
S. Ricciarini on the 20th of December 2005.. These positions were |
187 |
|
lightly approximated. |
188 |
|
|
189 |
|
ND GEOMETRY COMPLETED. |
190 |
|
The He3 and the polyethylene (CH2) have been added to fill |
191 |
|
the volumes NDTI and NDPB in the neutron detector. Leonov gave us the |
192 |
|
details of these materials. |
193 |
|
|
194 |
|
TOP PLATE GEOMETRY ADDED. |
195 |
|
The top plate geometry has been simulated as a N2 box that has the same |
196 |
|
dimensions of CATA. Inside it, at the right positions, there are S2 and CATA. |
197 |
|
The real top plate is a rectangular window having a thickness of 0.5 cm |
198 |
|
(volume TPTL emptied by the volume TPCV). This volume is filled with a mixture |
199 |
|
of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium |
200 |
|
are the four volumes TPTU, which are positioned at the corners of TPTL at the |
201 |
|
same height of CATA, and the four volumes TPTM, which are positioned at the |
202 |
|
corners of TPTL, at the same height of S2. |
203 |
|
The geometry of the top plate is based on a simplified version of the CAD |
204 |
|
drawings. |
205 |
|
|
206 |
|
October 2006, Bari |
207 |
|
|
208 |
|
The geometry of the neutron detector has been updated. Some dimensions of some |
209 |
|
volumes have been corrected and the aluminum cover and the aluminum boxes to |
210 |
|
put the cables have been added. A new material, the cadmium, has been also |
211 |
|
defined. |
212 |
|
|
213 |
|
September 2006, Bari |
214 |
|
|
215 |
|
SPHE and ND data card bugs fixed: the definition of the ND data card, |
216 |
|
missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE |
217 |
|
data card has been changed. Before the correction the data card: |
218 |
|
NDET 'SPHE' was used to delete the spherical top shell to substitute it with |
219 |
|
a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA. |
220 |
|
|
221 |

222 |
|
June 2006, Bari |
223 |
|
|
224 |
|
The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc) |
225 |
|
and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the |
226 |
|
nominal height as measured in PAMELA (See the document: "Main geometrical |
227 |
|
parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi, |
228 |
|
E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions |
229 |
|
of S21Y and S12X are higher than those in the cited document due to the fact |
230 |
|
that in GPAMELA the thickness of the mylar has been considered while in the |
231 |
|
document it has been neglected. |

|
GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED |
237 |
|
|
238 |
|
Routines to simulate the gigantic resonance of gammas in Tungsten |
239 |
|
have been added. The GPGIG routine is called in GUSTEP if a gamma |
240 |
|
enter the calorimeter absorber. This is the steering routine to |
241 |
|
simulate the production of neutrons from gigantic resonance. It |
242 |
|
does checks on STEP lenght. If the range is smaller than the other |
243 |
|
selected for that step, it does generate the neutron and stops the |
244 |
|
gamma. Please note that the neutron has now a new particle |
245 |
|
number. This is to tag the gigantic resonance neutrons. |

|
CAL HIT STRUCTURE BUGS FIXED |
251 |
|
|
252 |
|
The maximum number of hit is now different for the two hit |
253 |
|
structures: CALST and CALI. Vectors inizialization and HBOOK |
254 |
|
ntple booking have been updated. The GPDCAL routine has been fixed |
255 |
|
so to handle the case in wich hits stored are more than the maximum |
256 |
|
number of hit. |
257 |
|
In this case in the ntple up to the maximum number of hits will be stored. |

TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED |
262 |
|
|
263 |
|
The TOF geometry has been modified. The following boxes have been |
264 |
|
added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M, |
265 |
|
S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and |
266 |
|
S1 and S2 made of aluminum. Each scintillator paddle has been put |
267 |
|
in his mylar box and the other materials: air, polystyrene, and |
268 |
|
aluminum have been added at their nominal positions. According to |
269 |
|
Naples people the araldite glue has been simulated has an air |
270 |
|
gap. For this work two new materials: the Mylar (MYLAR) and the |
271 |
|
polystyrene (POLYSTYRENE) with a density of 35 g/l have been |
272 |
|
defined as a mixture. The positions of the three bottom |
273 |
|
scintillator planes that contain respectively the S12X, S22Y and |
274 |
|
S32X paddles have been regulated according on their official |
275 |
|
positions in PAMELA. |

GEN DATA CARD UPDATED |
280 |
|
|
281 |
|
To enable generation on a surface perpendicular to the XY plane, |
282 |
|
GEN gata card has been updated addingh a new parameter: ZDGEN. This is |
283 |
|
the dimension, along Z axis , of the generation surface. The Z |
284 |
|
position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER + |
285 |
|
ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3). |

|
GUHADR AND GUPHAD UPDATED |
290 |
|
|
291 |
|
To use GCALOR package the hadronic routines have been updated. The |
292 |
|
inizialization routine call CALSIG, while the other calls GCALOR. |
293 |
|
|
294 |
|
NEW GPKEY ADDED: GPCALOR |
295 |
|
|
296 |
|
This logical has been added to enable the GCALOR package. This flag |
297 |
|
is set to true in GPDAT if the data card: HPAK, is set to |
298 |
|
'GCAL'. The gpkey.inc has been update accordingly. |
299 |
|
|
300 |
|
|
301 |
|
NEUTRON DETECTOR ADDED. NEW DIR: GPND |
302 |
|
|
303 |
|
The neutron detector has been added. At the moment it is just the |
304 |
|
geometry. The directory structure of the repository has been |
305 |
|
updated as well. Dimensions has been taken from picture and |
306 |
|
literature. A full upgrade to the drawing is needed. |
307 |
|
|
308 |
|
GCALOR PACKAGE ADDED. NEW DIRs: GPCALOR, GPCALORDES |
309 |
|
|
310 |
|
GCALOR package contins the CALOR simulation code and an interface |
311 |
|
to use it in GEANT. The important feature for us is the usage of |
312 |
|
the MICAP code. This is facused on the low energy neutron |
313 |
|
simulation. for details see: |
314 |
|
http://www.staff.uni-mainz.de/zeitnitz/Gcalor/gcalor.html |
315 |
|
This package should be distributed with the GEANT library but is |
316 |
|
not up to date. I did download the latest release and stored into |
317 |
|
gpcalor directory of the gpamela tree. |
318 |
|
Then I did clean up the code substituting the explicit inclusion of |
319 |
|
the commons with a #include cpp directive. In parallel I did |
320 |
|
extract the commons to include files having the same common name. I |
321 |
|
did store the include files into a newly created directory: |
322 |
|
gpcalordes. |
323 |
|
The Makefile has been updated accordingly. |
324 |
|
Please note that to avoid conflict with CRENLIB distribution the gcalor source file has been named gpcalor.F |
325 |
|
NOTE: There are still problem due to different common sizes. In |
326 |
|
particular the common MICFIL is maller in the geant library |
327 |
|
libgeant.a . There the subroutines: gmorin, gmxsec, gmplxs, are |
328 |
|
present and linked using a wrong version of the common. This still needs to be debuged. |
329 |
|
NOTE2: The auxiliary files with the cross sections: chetc.dat.gz |
330 |
|
and xsneut.dat.gz, have been added to the aux directory and moved |
331 |
|
to the working directory, i.e. GPAMELA_BIN. The GCALOR routine will |
332 |
|
look for CERN_ROOT environment variable. If found files are |
333 |
|
searched there at first, then in the working directory. A fool |
334 |

NEW DATA CARD ADDED: HFSF |
352 |
|
|
353 |
|
To define a policy for the random number initial seeds |
354 |
|
definition. Using this card is possible to override GEANT seeds |
355 |
|
defined via NRDM card. The policy is selected according to the |
356 |
|
values: |
357 |
|
|
358 |
|
- 1: The seeds are initialized to the initial values found in a user |
359 |
|
defined file or the default file: INPUTSEED.DAT |
360 |
|
|
361 |
|
- 2: The seeds are initialized to the final values found in a user defined |
362 |
|
file or the default file: INPUTSEED.DAT |
363 |
|
|
364 |
|
The case 1 must be used in case the user needs to reproduce the |
365 |
|
random chain of a previous run. In this case the user can save the |
366 |
|
initial seeds, used in the run he would like to reproduce, in a |
367 |
|
binary file and pass the filename to the program using the *FLSF |
368 |
|
data card. In case the user file is not specified the default |
369 |
|
INPUTSEED.DAT will be used. |
370 |
|
|
371 |
|
The case 2 must be used in case the user needs to chain several |
372 |
|
GPAMELA run and likes to be sure he is starting the random |
373 |
|
generator using the right sequence. In this case the user must |
374 |
|
specify an input binary file using the *FLSF data card, otherwise |
375 |
|
the INPUTSEED.DAT file will be used. |
376 |
|
|
377 |
|
NEW DATA CARD ADDED: *FSFI |
378 |
|
|
379 |
|
Using this card the user can specify the logical unit and name of |
380 |
|
the file storing the initial seeds to be used to initialize the |
381 |
|
random number generator. This file must be a FORTRAN binary one |
382 |
|
storing four integer numbers. The first two are the number to be |
383 |
|
used in the case: HFSF=1, the other two will be used in the case: |
384 |
|
HFSF=2. This file can be one created by GPAMELA or by the user |
385 |
|
filled with his own seeds. For this purpose an utility program: |
386 |
|
writeseeds.f, has been added in the aux directory. In case the |
387 |
|
*FSFI card is not specified the default values: 24 and INPUTSEEDS.DAT, will |
388 |
|
be used as LUN and file name respectively. |
389 |
|
|
390 |
|
NEW DATA CARD ADDED: *LSFI |
391 |
|
|
392 |
|
Using this card the user can specify the logical unit and name of |
393 |
|
the file storing the first and last seeds used in the GPAMELA |
394 |
|
run. This file is a FORTRAN binary one. This file can be used as |
395 |
|
input one specifying it in the *FSFI data card of the next GPAMELA |
396 |
|
run. In case the *LSFI card is not specified the default values: 26 |
397 |
|
and HBOOKFILENAME.DAT (as sepified in *HFI), will be used as LUN |
398 |
|
and file name respectively. |
399 |
|
|
400 |
|
NEW UTILITY PROGRAMS ADDED: writeseeds.f, readseeds.f |
401 |
|
|
402 |
|
These new programs have been added in the aux directory. Using these a |
403 |
|
user defined seed file can be created and re-read. |
404 |
|
|
405 |
|
NEW VOLUMES ADDED: MSHE, BSPH; PRESSURIZED CONTAINER ADDED |
406 |
|
|
407 |
|
Alexey Bakaldin, in MEPHI, did add the PAMELA pressurized container to |
408 |
|
the simulation. He did defined new volumes filled with aluminum and |
409 |
|
placed inside the mother volume. Positions have been fine tuned by |
410 |
|
Marialuigia Ambriola and compared to the CAD drawings. |
411 |
|
Two new volumes have been added to simulate the container: |
412 |
|
- MSHE, a tube simulating the middle part of the container |
413 |
|
- BSPH, the spherical bottom part of the container |
414 |
|
|
415 |
|
To better simulate the upper part the SHEL volume has been modified |
416 |
|
into a cone. Dimentions of the top cover: TSPH, have been modified |
417 |
|
accordingly. |
418 |
|
|
419 |
|
DETECTOR POSITIONS REVIEWED |
420 |
|
|
421 |
|
All detector Z positions have been reviewd to fit into the |
422 |
|
simulated pressurized container. |

|
TRD GEOMETRY AND CALIBRATION REVIEWD |
425 |
|
|
426 |
|
The TRD geometry has been deeply reviewed. Using the CAD drawings |
427 |
|
the carbon fiber frames have been simulated and radiator dimentions |
428 |
|
corrected. For this reason the calibration done on the beam tests |
429 |
|
has been revied and new sets of calibration constants calculated |
430 |
|
comparing the beam test data with the GPAMELA results. The new |
431 |
|
constants are about 3% larger than the previous ones. |
432 |
|
|
433 |
|
TRACKER GEOMETRY REVIEWED. NEW VOLUME DEFINED: THBP, TPAS, TPAI |
434 |
|
|
435 |
|
Thanks to Lorenzo Bonechi for the drawings and explanations. Now the |
436 |
|
hybrd cards have been put into the simulation and the geometry updated |
437 |
|
considering the dead zones in the silicon detectors. The hybrid zone |
438 |
|
has been simulated as well. At the moment the hybrid is simulated as |
439 |
|
a G10 plates. The full height of the tracker magnet has been |
440 |
|
reviewed as well. |
441 |
|
|
442 |
|
The tracker ladder is now simulated inside a nitrogen box: TPAS, |
443 |
|
placed inside an aluminum frame: TRPB. Each silicon ladder has been |
444 |
|
simulated using two silicon blocks: TRSL, into each of this block a |
445 |
|
smaller silicon detector: TPAI, has been placed inside the larger |
446 |
|
silicon block TRSL. In this way the subdivided silicon ladder can |
447 |
|
be upgraded with an indipendend roto-translation for each sensor. |
448 |
|
|
449 |
|
The TRPB aluminum frame has been enlarged to fit the external |
450 |
|
magnet canister frame. |
451 |
|
|
452 |
|
The last plane has been flipped with a 180 degree rotation around |
453 |
|
the X axis. |

TRACKER HIT STRUCTURE REVIEWED |
456 |
|
|
457 |

Taking into account the new version of the tracker geometry, the hit |
458 |
|
structure for this detector has been revied. |

NON-REPRODUCIBILITY PROBLEM OF A GPAMELA RUN FIXED. |
468 |
|
The non-reproducibility of a GPAMELA run was due to the random number |
469 |
|
initialization in the GARFIELD code. In GARFIELD by default, the initial |
470 |
|
seeds of the random number generators are always the same while the random |
471 |
|
number generators are called a given number of times (determined by the |
472 |
|
hour of the day) during the initialization phase (see init.f subroutine in |
473 |
|
the GARFIELD code for details). Follows that different runs produce |
474 |
|
different results without changing the initial seeds. To have identical |
475 |
|
results in different runs, the GARFIELD program has to start typing the |
476 |
|
noRNDM_initialisation switch. To avoid of specifying this switch |
477 |
|
by the user, |
478 |
|
the GARFIELD package has been upgraded with a patch. In this way the problem |
479 |
|
is partially solved because, now, the initial seeds of the random generators |
480 |
|
in GARFIELD will be always the same even if the RNDM GEANT data card is |
481 |
|
activated by the user for changing the initial seeds in the GPAMELA program. |
482 |
|
Work is in progress for a more general correction of this problem. |
483 |
|
Please, use the updated GARFIELD code released with the CVS version v4r1 |
484 |
|
to fix this problem. |

RNDM ROUTINE REPLACED BY THE GRNDM ROUTINE IN GPXTR AND NPOISS. |
488 |
|
The obsolete RNDM random number generator has been replaced by the GEANT |
489 |
|
GRNDN routine in the gpxtr.F subroutine and in the npoiss.F function. |
490 |
|
|
491 |
|
BUG FOUND AND FIXED: the set and detector calorimeter addresses (ISCAL |
492 |
|
and IDCASI variables) used in GUTREV were respectively set to a fixed |
493 |
|
values of 12 and 1. The correct values of these variables are stored in |
494 |
|
the GPSED common when the set and the detector ZEBRA banks are filled |
495 |
|
during a run. In general the values of the set and detector addresses |
496 |
|
depend on the number of active detectors in a given run. ISCAL=12 and |
497 |
|
IDCASI=1 are only right when all the detectors of GPAMELA are active. |

CALORIMETER SIMULATION completed! The update of the geometry and of the |
502 |
|
special tracking parameters and the tuning of the calorimeter have been |
503 |
|
successfully done. A great quantity of simulated data have been produced |
504 |
|
in the calorimeter for different particles (muons, electrons and pions) |
505 |
|
and momenta (5 and 40 GeV/c) and the output data have been analyzed. The |
506 |
|
distributions of the total energy deposited in the calorimeter and the |
507 |
|
total number of strips hit have been compared with the respective |
508 |
|
distributions produced by the Trieste's tuned standalone Monte Carlo |
509 |
|
simulation program of the PAMELA calorimeter. The accord between the |
510 |
|
two simulations is excellent. Many thanks to Mirko for his collaboration. |
511 |
|
|
512 |
|
Working in progress on TRD. The GARFIELD interface to the HEED program is not |
513 |
|
optimized to track particle with a charge greater than one and photons. The |
514 |
|
program print a warning message to advise the user when it is the case. |

|
The buffer size of each column of the GPAMELA Ntuple has been increased to |
519 |
|
4096 and set equal to the record length, defined by a call to the HROPEN |
520 |
|
routine. |
521 |
|
Also the length of the common /PAWC/ (parameter NWPAW) has been increased |
522 |
|
to 1.34E8, according to the rule that it has to be larger than the number |
523 |
|
of columns times the buffer size. |

526 |
|
|
527 |
|
The variables in the HIT STRUCTURE of the CALORIMETER and their way to be |
528 |
|
filled have been changed according to the electronics system of the real |
529 |
|
detector. In fact, because each silicon detector (module) consists of |
530 |
|
32 strips and each strip is connected to those belonging to the two detectors |
531 |
|
of the same row (or column) for forming 24 cm long strips, the sum of the |
532 |
|
deposited energies in the strips forming a `long strip' is now calculated for |
533 |
|
each event (gpucal.F subroutine) and it is stored in a hit only at the |
534 |
|
end of the event (gutrev.F subroutine). |
535 |
|
The output variables of the GPAMELA en-tuple are then filled in the vectors |
536 |
|
ICAPLANE(NTHCAL), ICASTRIP(NTHCAL), ENESTRIP(NTHCAL) and ICAMOD(NTHCAL), |
537 |
|
by a call to the GPDCAL subroutine: |
538 |
|
-ICAPLANE(i) contains the number of hit plane; |
539 |
|
-ICASTRIP(i) contains the number of hit strip; |
540 |
|
-ICAMOD(i) can assume different values based on the number of times and |
541 |
|
positions in which a `long strip' has been hit. |
542 |
|
-ENESTRIP(i) contains the deposited energy in the hit strip; |
543 |
|
where i is the number of hit (1<i<4224). |
544 |
|
Note that in the calorimeter each hit is filled at the end of the event and |
545 |
|
that there is a hit for each `long strip' hit from |
546 |
|
the particle. This use of the hit structure is different for the other |
547 |
|
detectors and it has been considered to avoid a too big number of hit in the |
548 |
|
calorimeter due to the showers. Follows that NTHCAL, which is the |
549 |
|
max number of hit in the calorimeter, is equal to 4224, the total |
550 |
|
number of `long strips'. So, for each event, the real number of hit will |
551 |
|
be less or equal to 4224. |
552 |
|
ICAMOD(i) is an additional information that does not exist in the real |
553 |
|
detector: if the strip i (i=1,32) of the module 1 or 2 or 3 |
554 |
|
is hit, the value of ICAMOD(i) is respectively incremented of 1, 100, 10000. |
555 |
|
Analogously it is done, if it is the strip j (j=33,64) of the modules 4, 5 |
556 |
|
and 6 or if it is the strip k (k=65,96) of the modules 7, 8 and 9. |
557 |
|
For example if we consider the hit 1 of an event, we could read: |
558 |
|
ICASTRIP(1)=30, ICAPLANE(1)=21, ENESTRIP(1)=0.5E-03 and ICAMOD(1)=10001. |
559 |
|
It means that the hit 1 contains the information that in the strip 30 of the |
560 |
|
plane 21 has been deposited a total energy of 0.5E-03 GeV. In addition the |
561 |
|
`long strip 30' has been hit two times, one in the first module and the |
562 |
|
other in the third one. |
563 |
|
|
564 |
|
The energy deposited in the calorimeter is calculated in GeV. |
565 |
|
|
566 |
|
To store the hits in the calorimeter the subroutine GSAHIT is used instead of |
567 |
|
GSCHIT. |
568 |
|
|
569 |
|
To retrieve the hit structure the call to the routine GPRHIT is done instead |
570 |
|
of a call to the GFHITS subroutine. |

CALORIMETER geometry upgrade |
612 |
|
|
613 |
|
The volumes CAPD and CAAD have been taken off from the calorimeter. |
614 |
|
In addition the logical tree has been slightly changed to make the shifts of |
615 |
|
the silicon planes into the calorimeter box easier, i.e. the CAPL volume, |
616 |
|
which was made of the CASI, CAKP, CAGL, C10C and CAKA volumes, has |
617 |
|
been split up in the volumes CANS and CAPL. Now CANS is made of the CAKP, |
618 |
|
CAGL, C10C and CAKA volumes while CAPL contains the CASI volume, that has to |
619 |
|
be shifted as a function of the vertical position in the calorimeter. Also the |
620 |
|
dimensions of some volumes have been upgraded, including the external ones: |
621 |
|
CALB and CALS. CALS is an aluminum box of dimensions: 48.4*48.4*21.278 cm^3, |
622 |
|
having side-walls 1 cm thick and a bottom of 1 mm. The real box is more |
623 |
|
complicated and the configuration of the bottom should be upgraded if we want |
624 |
|
a reliable description of the event in the S4 scintillator. |

have the correct shape. The AC scintillators are placed in aluminum |
634 |
|
boxes with plastic rims inside. For these rims a 'new' material, PLAS, |
635 |
|
was defined. PLAS has all the characteristics of SCIN but is |
636 |
