70    November 2006, Bari
71    
72    TOF POSITIONS DEFINITELY UPDATED:
73    S2 and S1 have been positioned again, after the simulation of the top plate.
74    Before now, the positions were put ad hoc based on the positions given by
75    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
76    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
77    S. Ricciarini on the 20th of December 2005.. These positions were
78    lightly approximated.
79    
80    ND GEOMETRY COMPLETED.
81    The He3 and the polyethylene (CH2) have been added to fill
82    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
83    details of these materials.
84    
85    TOP PLATE GEOMETRY ADDED.
86    The top plate geometry has been simulated as a N2 box that has the same
87    dimensions of CATA. Inside it, at the right positions, there are S2 and CATA.
88    The real top plate is a rectangular window having a thickness of 0.5 cm
89    (volume TPTL emptied by the volume TPCV). This volume is filled with a mixture
90    of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium
91    are the four volumes TPTU, which are positioned at the corners of TPTL at the
92    same height of CATA, and the four volumes TPTM, which are positioned at the
93    corners of TPTL, at the same height of S2.
94    The geometry  of the top plate is based on a simplified version of the CAD
95    drawings.
96    
97    October 2006, Bari
98    
99    The geometry of the neutron detector has been updated. Some dimensions of some
100    volumes have been corrected and the aluminum cover and the aluminum boxes to
101    put the cables have been added. A new material, the cadmium, has been also
102    defined.
103    
104    September 2006, Bari
105    
106    SPHE and ND data card bugs fixed: the definition of the ND data card,
107    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
108    data card has been changed. Before the correction the data card:
109    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
110    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
111    
112    
113    June 2006, Bari
114    
115    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
116    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
117    nominal height as measured in PAMELA (See the document: "Main geometrical
118    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
119    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
120    of S21Y and S12X are higher than those in the cited document due to the fact
121    that in GPAMELA the thickness of the mylar has been considered while in the
122    document it has been neglected.
123    
124    
125    May 2006, Bari & Tor Vergata
126    
127    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
128    
129       Routines to simulate the gigantic resonance of gammas in Tungsten
130       have been added.  The GPGIG routine is called in GUSTEP if a gamma
131       enter the calorimeter absorber.  This is the steering routine to
132       simulate the production of neutrons from gigantic resonance.  It
133       does checks on STEP lenght. If the range is smaller than the other
134       selected for that step, it does generate the neutron and stops the
135       gamma. Please note that the neutron has now a new particle
136       number. This is to tag the gigantic resonance neutrons.
137    
138    
139    May 2006, Bari & Florence
140    
141    CAL HIT STRUCTURE BUGS FIXED
142    
143       The maximum number of hit is now different for the two hit
144       structures: CALST and CALI. Vectors inizialization and HBOOK
145       ntple booking have been updated. The GPDCAL routine has been fixed
146       so to handle the case in wich hits stored are more than the maximum
147       number of hit.
148       In this case in the ntple up to the maximum number of hits will be stored.
149    
150    April 2006, Bari
151    
152    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
153    
154       The TOF geometry has been modified. The following boxes have been
155       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
156       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
157       S1 and S2 made of aluminum. Each scintillator paddle has been put
158       in his mylar box and the other materials: air, polystyrene, and
159       aluminum have been added at their nominal positions.  According to
160       Naples people the araldite glue has been simulated has an air
161       gap. For this work two new materials: the Mylar (MYLAR) and the
162       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
163       defined as a mixture.  The positions of the three bottom
164       scintillator planes that contain respectively the S12X, S22Y and
165       S32X paddles have been regulated according on their official
166       positions in PAMELA.
167    
168    Mar 2006, Bari
169    
170    GEN DATA CARD UPDATED
171    
172       To enable generation on a surface perpendicular to the XY plane,
173       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
174       the dimension, along Z axis , of the generation surface. The Z
175       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
176       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).
177    
178    Nov 2005, Bari
179    
180    GUHADR AND GUPHAD UPDATED
181    
182       To use GCALOR package the hadronic routines have been updated. The
183       inizialization routine call CALSIG, while the other calls GCALOR.
184    
185    NEW GPKEY ADDED: GPCALOR
186    
187       This logical has been added to enable the GCALOR package. This flag
188       is set to true in GPDAT if the data card: HPAK, is set to
189       'GCAL'. The gpkey.inc has been update accordingly.
190    
191      
192    NEUTRON DETECTOR ADDED. NEW DIR: GPND
193    
194       The neutron detector has been added. At the moment it is just the
195       geometry. The directory structure of the repository has been
196       updated as well. Dimensions has been taken from picture and
197       literature. A full upgrade to the drawing is needed.
198    
199    GCALOR PACKAGE ADDED. NEW DIRs: GPCALOR, GPCALORDES
200    
201       GCALOR package contins the CALOR simulation code and an interface
202       to use it in GEANT. The important feature for us is the usage of
203       the MICAP code. This is facused on the low energy neutron
204       simulation. for details see:
205       http://www.staff.uni-mainz.de/zeitnitz/Gcalor/gcalor.html
206       This package should be distributed with the GEANT library but is
207       not up to date. I did download the latest release and stored into
208       gpcalor directory of the gpamela tree.
209       Then I did clean up the code substituting the explicit inclusion of
210       the commons with a #include cpp directive. In parallel I did
211       extract the commons to include files having the same common name. I
212       did store the include files into a newly created directory:
213       gpcalordes.
214       The Makefile has been updated accordingly.
215       Please note that to avoid conflict with CRENLIB distribution the gcalor source file has been named gpcalor.F
216       NOTE: There are still problem due to different common sizes. In
217       particular the common MICFIL is maller in the geant library
218       libgeant.a . There the subroutines: gmorin, gmxsec, gmplxs, are
219       present and linked using a wrong version of the common. This still needs to be debuged.
220       NOTE2: The auxiliary files with the cross sections: chetc.dat.gz
221       and xsneut.dat.gz, have been added to the aux directory and moved
222       to the working directory, i.e. GPAMELA_BIN. The GCALOR routine will
223       look for CERN_ROOT environment variable. If found files are
224       searched there at first, then in the working directory. A fool
225       proof policy has to be implemented to avoid problem with
226       synchronization fo these files.
227      
228    
229    The GCALOR package
230    
231    June 2005, Bari
232    
233    TOF SCINTILLATOR PADDLES UPDATED
234    
235       The dimensions and the number of the scintillator paddles for each
236       TOF planes have been updated.
237    
238    May 2005, Bari
239    
240    Some updates on the latest modification done in the past year.
241    
242    NEW DATA CARD ADDED: HFSF
243    
244       To define a policy for the random number initial seeds
245       definition. Using this card is possible to override GEANT seeds
246       defined via NRDM card. The policy is selected according to the
247       values:
248    
249       - 1: The seeds are initialized to the initial values found in a user
250            defined file or the default file: INPUTSEED.DAT
251      
252       - 2: The seeds are initialized to the final values found in a user defined
253            file or the default file: INPUTSEED.DAT
254    
255       The case 1 must be used in case the user needs to reproduce the
256       random chain of a previous run. In this case the user can save the
257       initial seeds, used in the run he would like to reproduce, in a
258       binary file and pass the filename to the program using the *FLSF
259       data card. In case the user file is not specified the default
260       INPUTSEED.DAT will be used.
261      
262       The case 2 must be used in case the user needs to chain several
263       GPAMELA run and likes to be sure he is starting the random
264       generator using the right sequence. In this case the user must
265       specify an input binary file using the *FLSF data card, otherwise
266       the INPUTSEED.DAT file will be used.
267    
268    NEW DATA CARD ADDED: *FSFI
269    
270       Using this card the user can specify the logical unit and name of
271       the file storing the initial seeds to be used to initialize the
272       random number generator. This file must be a FORTRAN binary one
273       storing four integer numbers. The first two are the number to be
274       used in the case: HFSF=1, the other two will be used in the case:
275       HFSF=2. This file can be one created by GPAMELA or by the user
276       filled with his own seeds. For this purpose an utility program:
277       writeseeds.f, has been added in the aux directory.  In case the
278       *FSFI card is not specified the default values: 24 and INPUTSEEDS.DAT, will
279       be used as LUN and file name respectively.
280      
281    NEW DATA CARD ADDED: *LSFI
282    
283       Using this card the user can specify the logical unit and name of
284       the file storing the first and last seeds used in the GPAMELA
285       run. This file is a FORTRAN binary one. This file can be used as
286       input one specifying it in the *FSFI data card of the next GPAMELA
287       run.  In case the *LSFI card is not specified the default values: 26
288       and HBOOKFILENAME.DAT (as sepified in *HFI), will be used as LUN
289       and file name respectively.
290      
291    NEW UTILITY PROGRAMS ADDED: writeseeds.f, readseeds.f
292    
293       These new programs have been added in the aux directory. Using these a
294       user defined seed file can be created and re-read.
295    
296    NEW VOLUMES ADDED: MSHE, BSPH; PRESSURIZED CONTAINER ADDED
297    
298       Alexey Bakaldin, in MEPHI, did add the PAMELA pressurized container to
299       the simulation. He did defined new volumes filled with aluminum and
300       placed inside the mother volume. Positions have been fine tuned by
301       Marialuigia Ambriola and compared to the CAD drawings.
302       Two new volumes have been added to simulate the container:
303       - MSHE, a tube simulating the middle part of the container
304       - BSPH, the spherical bottom part of the container
305    
306       To better simulate the upper part the SHEL volume has been modified
307       into a cone. Dimentions of the top cover: TSPH, have been modified
308       accordingly.
309    
310    DETECTOR POSITIONS REVIEWED
311    
312       All detector Z positions have been reviewd to fit into the
313       simulated pressurized container.
314    
315    TRD GEOMETRY AND CALIBRATION REVIEWD
316    
317       The TRD geometry has been deeply reviewed. Using the CAD drawings
318       the carbon fiber frames have been simulated and radiator dimentions
319       corrected. For this reason the calibration done on the beam tests
320       has been revied and new sets of calibration constants calculated
321       comparing the beam test data with the GPAMELA results. The new
322       constants are about 3% larger than the previous ones.
323      
324    TRACKER GEOMETRY REVIEWED. NEW VOLUME DEFINED: THBP, TPAS, TPAI
325      
326       Thanks to Lorenzo Bonechi for the drawings and explanations. Now the
327       hybrd cards have been put into the simulation and the geometry updated
328       considering the dead zones in the silicon detectors. The hybrid zone
329       has been simulated as well. At the moment the hybrid is simulated as
330       a G10 plates. The full height of the tracker magnet has been
331       reviewed as well.
332    
333       The tracker ladder is now simulated inside a nitrogen box: TPAS,
334       placed inside an aluminum frame: TRPB. Each silicon ladder has been
335       simulated using two silicon blocks: TRSL, into each of this block a
336       smaller silicon detector: TPAI, has been placed inside the larger
337       silicon block TRSL. In this way the subdivided silicon ladder can
338       be upgraded with an indipendend roto-translation for each sensor.
339      
340       The TRPB aluminum frame has been enlarged to fit the external
341       magnet canister frame.
342      
343       The last plane has been flipped with a 180 degree rotation around
344       the X axis.
345      
346    TRACKER HIT STRUCTURE REVIEWED
347    
348       Taking into account the new version of the tracker geometry, the hit
349       structure for this detector has been revied.
350    
351    CALORIMETER GEOMETRY REVIEWED
352    
353       Marco Albi reviewed the calorimeter dimentions and positioning.
354    
355    
356    29 March 2004, Bari
357    
358    NON-REPRODUCIBILITY PROBLEM OF A GPAMELA RUN FIXED.
359       The non-reproducibility of a GPAMELA run was due to the random number
360       initialization in the GARFIELD code. In GARFIELD by default, the initial
361       seeds of the random number generators are always the same while the random
362       number generators are called a given number of times (determined by the
363       hour of the day) during the initialization phase (see init.f subroutine in
364       the GARFIELD code for details). Follows that different runs produce
365       different results without changing the initial seeds. To have identical
366       results in different runs, the GARFIELD program has to start typing the
367       noRNDM_initialisation switch. To avoid of specifying this switch
368       by the user,
369       the GARFIELD package has been upgraded with a patch. In this way the problem
370       is partially solved because, now, the initial seeds of the random generators
371       in GARFIELD will be always the same even if the RNDM GEANT data card is
372       activated by the user for changing the initial seeds in the GPAMELA program.
373       Work is in progress for a more general correction of this problem.
374       Please, use the updated GARFIELD code released with the CVS version v4r1
375       to fix this problem.  
376    
377    
378    RNDM ROUTINE REPLACED BY THE GRNDM ROUTINE IN GPXTR AND NPOISS.
379       The obsolete RNDM random number generator has been replaced by the GEANT
380       GRNDN routine in the gpxtr.F subroutine and in the npoiss.F function.
381    
382    BUG FOUND AND FIXED: the set and detector calorimeter addresses (ISCAL
383       and IDCASI variables) used in GUTREV were respectively set to a fixed
384       values of 12 and 1. The correct values of these variables are stored in
385       the GPSED common when the set and the detector ZEBRA banks are filled
386       during a run. In general the values of the set and detector addresses
387       depend on the number of active detectors in a given run. ISCAL=12 and
388       IDCASI=1 are only right when all the detectors of GPAMELA are active.
389    
390    9 December 2003, Bari
391    
392       CALORIMETER SIMULATION completed! The update of the geometry and of the
393       special tracking parameters and the tuning of the calorimeter have been
394       successfully done. A great quantity of simulated data have been produced
395       in the calorimeter for different particles (muons, electrons and pions)
396       and momenta (5 and 40 GeV/c) and the output data have been analyzed. The
397       distributions of the total energy deposited in the calorimeter and the
398       total number of strips hit have been compared with the respective
399       distributions produced by the Trieste's tuned standalone Monte Carlo
400       simulation program of the PAMELA calorimeter. The accord between the
401       two simulations is excellent. Many thanks to Mirko for his collaboration.
402    
403       Working in progress on TRD. The GARFIELD interface to the HEED program is not
404       optimized to track particle with a charge greater than one and photons. The

409       The buffer size of each column of the GPAMELA Ntuple has been increased to
410       4096 and set equal to the record length, defined by a call to the HROPEN
411       routine.
412       Also the length of the common /PAWC/ (parameter NWPAW) has been increased
413       to 1.34E8, according to the rule that it has to be larger than the number
414       of columns times the buffer size.

418       The variables in the HIT STRUCTURE of the CALORIMETER and their way to be
419       filled have been changed according to the electronics system of the real
420       detector. In fact, because each silicon detector (module) consists of
421       32 strips and each strip is connected to those belonging to the two detectors
422       of the same row (or column) for forming 24 cm long strips, the sum of the
423       deposited energies in the strips forming a `long strip' is now calculated for
424       each event (gpucal.F subroutine) and it is stored in a hit only at the
425       end of the event (gutrev.F subroutine).
426       The output variables of the GPAMELA en-tuple are then filled in the vectors
427       ICAPLANE(NTHCAL), ICASTRIP(NTHCAL), ENESTRIP(NTHCAL) and ICAMOD(NTHCAL),
428       by a call to the GPDCAL subroutine:
429       -ICAPLANE(i) contains the number of hit plane;
430       -ICASTRIP(i) contains the number of hit strip;
431       -ICAMOD(i) can assume different values based on the number of times and
432                  positions in which a `long strip' has been hit.
433       -ENESTRIP(i) contains the deposited energy in the hit strip;
434       where i is the number of hit (1<i<4224).
435       Note that in the calorimeter each hit is filled at the end of the event and
436       that there is a hit for each `long strip' hit from
437       the particle. This use of the hit structure is different for the other
438       detectors and it has been considered to avoid a too big number of hit in the
439       calorimeter due to the showers. Follows that NTHCAL, which is the
440       max number of hit in the calorimeter, is equal to 4224, the total
441       number of `long strips'. So, for each event, the real number of hit will
442       be less or equal to 4224.
443       ICAMOD(i) is an additional information that does not exist in the real
444       detector: if the strip i (i=1,32) of the module 1 or 2 or 3
445       is hit, the value of ICAMOD(i) is respectively incremented of 1, 100, 10000.
446       Analogously it is done, if it is the strip j (j=33,64) of the modules 4, 5
447       and 6 or if it is the strip k (k=65,96) of the modules 7, 8 and 9.
448       For example if we consider the hit 1 of an event, we could read:
449       ICASTRIP(1)=30, ICAPLANE(1)=21, ENESTRIP(1)=0.5E-03 and ICAMOD(1)=10001.
450       It means that the hit 1 contains the information that in the strip 30 of the
451       plane 21 has been deposited a total energy of 0.5E-03 GeV. In addition the
452       `long strip 30' has been hit two times, one in the first module and the
453       other in the third one.
454    
455       The energy deposited in the calorimeter is calculated in GeV.
456    
457       To store the hits in the calorimeter the subroutine GSAHIT is used instead of
458       GSCHIT.
459    
460       To retrieve the hit structure the call to the routine GPRHIT is done instead
461       of a call to the GFHITS subroutine.

502    CALORIMETER geometry upgrade
503    
504       The volumes CAPD and CAAD have been taken off from the calorimeter.
505       In addition the logical tree has been slightly changed to make the shifts of
506       the silicon planes into the calorimeter box easier, i.e. the CAPL volume,
507       which was made of the CASI, CAKP, CAGL, C10C and CAKA volumes, has
508       been split up in the volumes CANS and CAPL. Now CANS is made of the CAKP,
509       CAGL, C10C and CAKA volumes while CAPL contains the CASI volume, that has to
510       be shifted as a function of the vertical position in the calorimeter. Also the
511       dimensions of some volumes have been upgraded, including the external ones:
512       CALB and CALS. CALS is an aluminum box of dimensions: 48.4*48.4*21.278 cm^3,
513       having side-walls 1 cm thick and a bottom of 1 mm. The real box is more
514       complicated and the configuration of the bottom should be upgraded if we want
515       a reliable description of the event in the S4 scintillator.

519    ANTICOINC. GEOMETRY UPGRADE
520    
521       The AC geometry has been updated. The top AC scintillator (CAT) now
522       consists of 1 single sheet of scintillator with a hole in the middle
523       and the correct geometry(*). The side AC scintillators (CAS) also
524       have the correct shape. The AC scintillators are placed in aluminum
525       boxes with plastic rims inside. For these rims a 'new' material, PLAS,
526       was defined. PLAS has all the characteristics of SCIN but is
527       non-sensitive. No PMTs or PMT holders have been modelled.
528       (*)-The interfaces on CAT where the PMTs should be located are
529           slightly different from the real case.
