81    
82    November 2006, Bari
83    
84    
85    S4 GEOMETRY UPDATED:
86    The x and y dimensions have been corrected because they were wrong.
87    A container of aluminum has been added having walls of thickness equal
88    to 0.1 cm.  
89    
90    TOF POSITIONS DEFINITELY UPDATED:
91    S2 and S1 have been positioned again, after the simulation of the top plate.
92    Before now, the positions were put by hand based on the positions given by
93    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
94    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
95    S. Ricciarini on the 20th of December 2005.. These positions were
96    lightly approximated because the thicknesses of the mylar and of the glue were
97    not considered in that document. Also the height of S3 has been modified as
98    suggested from the Naples PAMELA collaborators.
99    
100    ND GEOMETRY COMPLETED.
101    The He3 and the polyethylene (CH2) have been added to fill
102    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
103    details of these materials.
104    
105    TOP PLATE GEOMETRY ADDED.
106    The top plate geometry has been simulated as a rectangular window filled
107    with a mixture of titanium (90%), aluminum (6%) and vanadium (4%). It has been
108    put in a N2 box having the same planar dimensions of CATA. In this box there
109    are also S2 and CATA at the right positions. Then the top plate geometry has
110    been completed with other eight small volumes of titanium positioned at the
111    corners of the N2 box. Four of them are at the same height of CATA, the
112    other four are at the same height of S2. The simulated geometry of the top
113    plate is based on a simplified version of the CAD drawings.
114    
115    October 2006, Bari
116    
117    The geometry of the neutron detector has been updated. Some dimensions of some
118    volumes have been corrected and the aluminum cover and the aluminum boxes to
119    put the cables have been added. A new material, the cadmium, has been also
120    defined.
121    
122    September 2006, Bari
123    
124    SPHE and ND data card bugs fixed: the definition of the ND data card,
125    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
126    data card has been changed. Before the correction the data card:
127    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
128    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
129    
130    
131    June 2006, Bari
132    
133    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
134    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
135    nominal height as measured in PAMELA (See the document: "Main geometrical
136    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
137    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
138    of S21Y and S12X are higher than those in the cited document due to the fact
139    that in GPAMELA the thickness of the mylar has been considered while in the
140    document it has been neglected.
141    
142    
143    May 2006, Bari & Tor Vergata
144    
145    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
146    
147       Routines to simulate the gigantic resonance of gammas in Tungsten
148       have been added.  The GPGIG routine is called in GUSTEP if a gamma
149       enter the calorimeter absorber.  This is the steering routine to
150       simulate the production of neutrons from gigantic resonance.  It
151       does checks on STEP lenght. If the range is smaller than the other
152       selected for that step, it does generate the neutron and stops the
153       gamma. Please note that the neutron has now a new particle
154       number. This is to tag the gigantic resonance neutrons.
155    
156    
157    May 2006, Bari & Florence
158    
159    CAL HIT STRUCTURE BUGS FIXED
160    
161       The maximum number of hit is now different for the two hit
162       structures: CALST and CALI. Vectors inizialization and HBOOK
163       ntple booking have been updated. The GPDCAL routine has been fixed
164       so to handle the case in wich hits stored are more than the maximum
165       number of hit.
166       In this case in the ntple up to the maximum number of hits will be stored.
167    
168    April 2006, Bari
169    
170    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
171    
172       The TOF geometry has been modified. The following boxes have been
173       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
174       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
175       S1 and S2 made of aluminum. Each scintillator paddle has been put
176       in his mylar box and the other materials: air, polystyrene, and
177       aluminum have been added at their nominal positions.  According to
178       Naples people the araldite glue has been simulated has an air
179       gap. For this work two new materials: the Mylar (MYLAR) and the
180       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
181       defined as a mixture.  The positions of the three bottom
182       scintillator planes that contain respectively the S12X, S22Y and
183       S32X paddles have been regulated according on their official
184       positions in PAMELA.
185    
186    Mar 2006, Bari
187    
188    GEN DATA CARD UPDATED
189    
190       To enable generation on a surface perpendicular to the XY plane,
191       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
192       the dimension, along Z axis , of the generation surface. The Z
193       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
194       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).
195    
196    Nov 2005, Bari
197    
198    GUHADR AND GUPHAD UPDATED
199    
200       To use GCALOR package the hadronic routines have been updated. The
201       inizialization routine call CALSIG, while the other calls GCALOR.
202    
203    NEW GPKEY ADDED: GPCALOR
204    
205       This logical has been added to enable the GCALOR package. This flag
206       is set to true in GPDAT if the data card: HPAK, is set to
207       'GCAL'. The gpkey.inc has been update accordingly.
208    
209      
210    NEUTRON DETECTOR ADDED. NEW DIR: GPND
211    
212       The neutron detector has been added. At the moment it is just the
213       geometry. The directory structure of the repository has been
214       updated as well. Dimensions has been taken from picture and
215       literature. A full upgrade to the drawing is needed.
216    
217    GCALOR PACKAGE ADDED. NEW DIRs: GPCALOR, GPCALORDES
218    
219       GCALOR package contins the CALOR simulation code and an interface
220       to use it in GEANT. The important feature for us is the usage of
221       the MICAP code. This is facused on the low energy neutron
222       simulation. for details see:
223       http://www.staff.uni-mainz.de/zeitnitz/Gcalor/gcalor.html
224       This package should be distributed with the GEANT library but is
225       not up to date. I did download the latest release and stored into
226       gpcalor directory of the gpamela tree.
227       Then I did clean up the code substituting the explicit inclusion of
228       the commons with a #include cpp directive. In parallel I did
229       extract the commons to include files having the same common name. I
230       did store the include files into a newly created directory:
231       gpcalordes.
232       The Makefile has been updated accordingly.
233       Please note that to avoid conflict with CRENLIB distribution the gcalor source file has been named gpcalor.F
234       NOTE: There are still problem due to different common sizes. In
235       particular the common MICFIL is maller in the geant library
236       libgeant.a . There the subroutines: gmorin, gmxsec, gmplxs, are
237       present and linked using a wrong version of the common. This still needs to be debuged.
238       NOTE2: The auxiliary files with the cross sections: chetc.dat.gz
239       and xsneut.dat.gz, have been added to the aux directory and moved
240       to the working directory, i.e. GPAMELA_BIN. The GCALOR routine will
241       look for CERN_ROOT environment variable. If found files are
242       searched there at first, then in the working directory. A fool
243       proof policy has to be implemented to avoid problem with
244       synchronization fo these files.
245      
246    
247    The GCALOR package
248    
249    June 2005, Bari
250    
251    TOF SCINTILLATOR PADDLES UPDATED
252    
253       The dimensions and the number of the scintillator paddles for each
254       TOF planes have been updated.
255    
256    May 2005, Bari
257    
258    Some updates on the latest modification done in the past year.
259    
260    NEW DATA CARD ADDED: HFSF
261    
262       To define a policy for the random number initial seeds
263       definition. Using this card is possible to override GEANT seeds
264       defined via NRDM card. The policy is selected according to the
265       values:
266    
267       - 1: The seeds are initialized to the initial values found in a user
268            defined file or the default file: INPUTSEED.DAT
269      
270       - 2: The seeds are initialized to the final values found in a user defined
271            file or the default file: INPUTSEED.DAT
272    
273       The case 1 must be used in case the user needs to reproduce the
274       random chain of a previous run. In this case the user can save the
275       initial seeds, used in the run he would like to reproduce, in a
276       binary file and pass the filename to the program using the *FLSF
277       data card. In case the user file is not specified the default
278       INPUTSEED.DAT will be used.
279      
280       The case 2 must be used in case the user needs to chain several
281       GPAMELA run and likes to be sure he is starting the random
282       generator using the right sequence. In this case the user must
283       specify an input binary file using the *FLSF data card, otherwise
284       the INPUTSEED.DAT file will be used.
285    
286    NEW DATA CARD ADDED: *FSFI
287    
288       Using this card the user can specify the logical unit and name of
289       the file storing the initial seeds to be used to initialize the
290       random number generator. This file must be a FORTRAN binary one
291       storing four integer numbers. The first two are the number to be
292       used in the case: HFSF=1, the other two will be used in the case:
293       HFSF=2. This file can be one created by GPAMELA or by the user
294       filled with his own seeds. For this purpose an utility program:
295       writeseeds.f, has been added in the aux directory.  In case the
296       *FSFI card is not specified the default values: 24 and INPUTSEEDS.DAT, will
297       be used as LUN and file name respectively.
298      
299    NEW DATA CARD ADDED: *LSFI
300    
301       Using this card the user can specify the logical unit and name of
302       the file storing the first and last seeds used in the GPAMELA
303       run. This file is a FORTRAN binary one. This file can be used as
304       input one specifying it in the *FSFI data card of the next GPAMELA
305       run.  In case the *LSFI card is not specified the default values: 26
306       and HBOOKFILENAME.DAT (as sepified in *HFI), will be used as LUN
307       and file name respectively.
308      
309    NEW UTILITY PROGRAMS ADDED: writeseeds.f, readseeds.f
310    
311       These new programs have been added in the aux directory. Using these a
312       user defined seed file can be created and re-read.
313    
314    NEW VOLUMES ADDED: MSHE, BSPH; PRESSURIZED CONTAINER ADDED
315    
316       Alexey Bakaldin, in MEPHI, did add the PAMELA pressurized container to
317       the simulation. He did defined new volumes filled with aluminum and
318       placed inside the mother volume. Positions have been fine tuned by
319       Marialuigia Ambriola and compared to the CAD drawings.
320       Two new volumes have been added to simulate the container:
321       - MSHE, a tube simulating the middle part of the container
322       - BSPH, the spherical bottom part of the container
323    
324       To better simulate the upper part the SHEL volume has been modified
325       into a cone. Dimentions of the top cover: TSPH, have been modified
326       accordingly.
327    
328    DETECTOR POSITIONS REVIEWED
329    
330       All detector Z positions have been reviewd to fit into the
331       simulated pressurized container.
332    
333    TRD GEOMETRY AND CALIBRATION REVIEWD
334    
335       The TRD geometry has been deeply reviewed. Using the CAD drawings
336       the carbon fiber frames have been simulated and radiator dimentions
337       corrected. For this reason the calibration done on the beam tests
338       has been revied and new sets of calibration constants calculated
339       comparing the beam test data with the GPAMELA results. The new
340       constants are about 3% larger than the previous ones.
341      
342    TRACKER GEOMETRY REVIEWED. NEW VOLUME DEFINED: THBP, TPAS, TPAI
343      
344       Thanks to Lorenzo Bonechi for the drawings and explanations. Now the
345       hybrd cards have been put into the simulation and the geometry updated
346       considering the dead zones in the silicon detectors. The hybrid zone
347       has been simulated as well. At the moment the hybrid is simulated as
348       a G10 plates. The full height of the tracker magnet has been
349       reviewed as well.
350    
351       The tracker ladder is now simulated inside a nitrogen box: TPAS,
352       placed inside an aluminum frame: TRPB. Each silicon ladder has been
353       simulated using two silicon blocks: TRSL, into each of this block a
354       smaller silicon detector: TPAI, has been placed inside the larger
355       silicon block TRSL. In this way the subdivided silicon ladder can
356       be upgraded with an indipendend roto-translation for each sensor.
357      
358       The TRPB aluminum frame has been enlarged to fit the external
359       magnet canister frame.
360      
361       The last plane has been flipped with a 180 degree rotation around
362       the X axis.
363      
364    TRACKER HIT STRUCTURE REVIEWED
365    
366       Taking into account the new version of the tracker geometry, the hit
367       structure for this detector has been revied.
368    
369    CALORIMETER GEOMETRY REVIEWED
370    
371       Marco Albi reviewed the calorimeter dimentions and positioning.
372    
373    
374    29 March 2004, Bari
375    
376    NON-REPRODUCIBILITY PROBLEM OF A GPAMELA RUN FIXED.
377       The non-reproducibility of a GPAMELA run was due to the random number
378       initialization in the GARFIELD code. In GARFIELD by default, the initial
379       seeds of the random number generators are always the same while the random
380       number generators are called a given number of times (determined by the
381       hour of the day) during the initialization phase (see init.f subroutine in
382       the GARFIELD code for details). Follows that different runs produce
383       different results without changing the initial seeds. To have identical
384       results in different runs, the GARFIELD program has to start typing the
385       noRNDM_initialisation switch. To avoid of specifying this switch
386       by the user,
387       the GARFIELD package has been upgraded with a patch. In this way the problem
388       is partially solved because, now, the initial seeds of the random generators
389       in GARFIELD will be always the same even if the RNDM GEANT data card is
390       activated by the user for changing the initial seeds in the GPAMELA program.
391       Work is in progress for a more general correction of this problem.
392       Please, use the updated GARFIELD code released with the CVS version v4r1
393       to fix this problem.  
394    
395    
396    RNDM ROUTINE REPLACED BY THE GRNDM ROUTINE IN GPXTR AND NPOISS.
397       The obsolete RNDM random number generator has been replaced by the GEANT
398       GRNDN routine in the gpxtr.F subroutine and in the npoiss.F function.
399    
400    BUG FOUND AND FIXED: the set and detector calorimeter addresses (ISCAL
401       and IDCASI variables) used in GUTREV were respectively set to a fixed
402       values of 12 and 1. The correct values of these variables are stored in
403       the GPSED common when the set and the detector ZEBRA banks are filled
404       during a run. In general the values of the set and detector addresses
405       depend on the number of active detectors in a given run. ISCAL=12 and
406       IDCASI=1 are only right when all the detectors of GPAMELA are active.

410       CALORIMETER SIMULATION completed! The update of the geometry and of the
411       special tracking parameters and the tuning of the calorimeter have been
412       successfully done. A great quantity of simulated data have been produced
413       in the calorimeter for different particles (muons, electrons and pions)
414       and momenta (5 and 40 GeV/c) and the output data have been analyzed. The
415       distributions of the total energy deposited in the calorimeter and the
416       total number of strips hit have been compared with the respective
417       distributions produced by the Trieste's tuned standalone Monte Carlo
418       simulation program of the PAMELA calorimeter. The accord between the
419       two simulations is excellent. Many thanks to Mirko for his collaboration.
420    
421       Working in progress on TRD. The GARFIELD interface to the HEED program is not
422       optimized to track particle with a charge greater than one and photons. The
423       program print a warning message to advise the user when it is the case.

427       The buffer size of each column of the GPAMELA Ntuple has been increased to
428       4096 and set equal to the record length, defined by a call to the HROPEN
429       routine.
430       Also the length of the common /PAWC/ (parameter NWPAW) has been increased
431       to 1.34E8, according to the rule that it has to be larger than the number
432       of columns times the buffer size.

435    
436       The variables in the HIT STRUCTURE of the CALORIMETER and their way to be
437       filled have been changed according to the electronics system of the real
438       detector. In fact, because each silicon detector (module) consists of
439       32 strips and each strip is connected to those belonging to the two detectors
440       of the same row (or column) for forming 24 cm long strips, the sum of the
441       deposited energies in the strips forming a `long strip' is now calculated for
442       each event (gpucal.F subroutine) and it is stored in a hit only at the
443       end of the event (gutrev.F subroutine).
444       The output variables of the GPAMELA en-tuple are then filled in the vectors
445       ICAPLANE(NTHCAL), ICASTRIP(NTHCAL), ENESTRIP(NTHCAL) and ICAMOD(NTHCAL),
446       by a call to the GPDCAL subroutine:
447       -ICAPLANE(i) contains the number of hit plane;
448       -ICASTRIP(i) contains the number of hit strip;
449       -ICAMOD(i) can assume different values based on the number of times and
450                  positions in which a `long strip' has been hit.
451       -ENESTRIP(i) contains the deposited energy in the hit strip;
452       where i is the number of hit (1<i<4224).
453       Note that in the calorimeter each hit is filled at the end of the event and
454       that there is a hit for each `long strip' hit from
455       the particle. This use of the hit structure is different for the other
456       detectors and it has been considered to avoid a too big number of hit in the
457       calorimeter due to the showers. Follows that NTHCAL, which is the
458       max number of hit in the calorimeter, is equal to 4224, the total
459       number of `long strips'. So, for each event, the real number of hit will
460       be less or equal to 4224.
461       ICAMOD(i) is an additional information that does not exist in the real
462       detector: if the strip i (i=1,32) of the module 1 or 2 or 3
463       is hit, the value of ICAMOD(i) is respectively incremented of 1, 100, 10000.
464       Analogously it is done, if it is the strip j (j=33,64) of the modules 4, 5
465       and 6 or if it is the strip k (k=65,96) of the modules 7, 8 and 9.
466       For example if we consider the hit 1 of an event, we could read:
467       ICASTRIP(1)=30, ICAPLANE(1)=21, ENESTRIP(1)=0.5E-03 and ICAMOD(1)=10001.
468       It means that the hit 1 contains the information that in the strip 30 of the
469       plane 21 has been deposited a total energy of 0.5E-03 GeV. In addition the
470       `long strip 30' has been hit two times, one in the first module and the
471       other in the third one.
472    
473       The energy deposited in the calorimeter is calculated in GeV.
474    
475       To store the hits in the calorimeter the subroutine GSAHIT is used instead of
476       GSCHIT.
477    
478       To retrieve the hit structure the call to the routine GPRHIT is done instead
479       of a call to the GFHITS subroutine.

520    CALORIMETER geometry upgrade
521    
522       The volumes CAPD and CAAD have been taken off from the calorimeter.
523       In addition the logical tree has been slightly changed to make the shifts of
524       the silicon planes into the calorimeter box easier, i.e. the CAPL volume,
525       which was made of the CASI, CAKP, CAGL, C10C and CAKA volumes, has
526       been split up in the volumes CANS and CAPL. Now CANS is made of the CAKP,
527       CAGL, C10C and CAKA volumes while CAPL contains the CASI volume, that has to
528       be shifted as a function of the vertical position in the calorimeter. Also the
529       dimensions of some volumes have been upgraded, including the external ones:
530       CALB and CALS. CALS is an aluminum box of dimensions: 48.4*48.4*21.278 cm^3,
531       having side-walls 1 cm thick and a bottom of 1 mm. The real box is more
532       complicated and the configuration of the bottom should be upgraded if we want
533       a reliable description of the event in the S4 scintillator.

537    ANTICOINC. GEOMETRY UPGRADE
538    
539       The AC geometry has been updated. The top AC scintillator (CAT) now
540       consists of 1 single sheet of scintillator with a hole in the middle
541       and the correct geometry(*). The side AC scintillators (CAS) also
542       have the correct shape. The AC scintillators are placed in aluminum
543       boxes with plastic rims inside. For these rims a 'new' material, PLAS,
544       was defined. PLAS has all the characteristics of SCIN but is
545       non-sensitive. No PMTs or PMT holders have been modelled.
546       (*)-The interfaces on CAT where the PMTs should be located are
547           slightly different from the real case.
