67    October 2006, Bari
68    
69    The geometry of the neutron detector has been updated. Some dimensions of some
70    volumes have been corrected while the aluminum cover and the aluminum boxes to
71    put the cables have been added. A new material, the cadmium, has been also
72    defined.
73    
74    September 2006, Bari
75    
76    SPHE and ND data card bugs fixed: the definition of the ND data card,
77    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
78    data card has been changed. Before the correction the data card:
79    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
80    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
81    
82    
83    June 2006, Bari
84    
85    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
86    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
87    nominal height as measured in PAMELA (See the document: "Main geometrical
88    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
89    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
90    of S21Y and S12X are higher than those in the cited document due to the fact
91    that in GPAMELA the thickness of the mylar has been considered while in the
92    document it has been neglected.
93    
94    
95    May 2006, Bari & Tor Vergata
96    
97    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
98    
99       Routines to simulate the gigantic resonance of gammas in Tungsten
100       have been added.  The GPGIG routine is called in GUSTEP if a gamma
101       enter the calorimeter absorber.  This is the steering routine to
102       simulate the production of neutrons from gigantic resonance.  It
103       does checks on STEP lenght. If the range is smaller than the other
104       selected for that step, it does generate the neutron and stops the
105       gamma. Please note that the neutron has now a new particle
106       number. This is to tag the gigantic resonance neutrons.
107    
108    
109    May 2006, Bari & Florence
110    
111    CAL HIT STRUCTURE BUGS FIXED
112    
113       The maximum number of hit is now different for the two hit
114       structures: CALST and CALI. Vectors inizialization and HBOOK
115       ntple booking have been updated. The GPDCAL routine has been fixed
116       so to handle the case in wich hits stored are more than the maximum
117       number of hit.
118       In this case in the ntple up to the maximum number of hits will be stored.
119    
120    April 2006, Bari
121    
122    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
123    
124       The TOF geometry has been modified. The following boxes have been
125       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
126       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
127       S1 and S2 made of aluminum. Each scintillator paddle has been put
128       in his mylar box and the other materials: air, polystyrene, and
129       aluminum have been added at their nominal positions.  According to
130       Naples people the araldite glue has been simulated has an air
131       gap. For this work two new materials: the Mylar (MYLAR) and the
132       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
133       defined as a mixture.  The positions of the three bottom
134       scintillator planes that contain respectively the S12X, S22Y and
135       S32X paddles have been regulated according on their official
136       positions in PAMELA.
137    
138    Mar 2006, Bari
139    
140    GEN DATA CARD UPDATED
141    
142       To enable generation on a surface perpendicular to the XY plane,
143       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
144       the dimension, along Z axis , of the generation surface. The Z
145       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
146       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).
147    
148    Nov 2005, Bari
149    
150    GUHADR AND GUPHAD UPDATED
151    
152       To use GCALOR package the hadronic routines have been updated. The
153       inizialization routine call CALSIG, while the other calls GCALOR.
154    
155    NEW GPKEY ADDED: GPCALOR
156    
157       This logical has been added to enable the GCALOR package. This flag
158       is set to true in GPDAT if the data card: HPAK, is set to
159       'GCAL'. The gpkey.inc has been update accordingly.
160    
161      
162    NEUTRON DETECTOR ADDED. NEW DIR: GPND
163    
164       The neutron detector has been added. At the moment it is just the
165       geometry. The directory structure of the repository has been
166       updated as well. Dimensions has been taken from picture and
167       literature. A full upgrade to the drawing is needed.
168    
169    GCALOR PACKAGE ADDED. NEW DIRs: GPCALOR, GPCALORDES
170    
171       GCALOR package contins the CALOR simulation code and an interface
172       to use it in GEANT. The important feature for us is the usage of
173       the MICAP code. This is facused on the low energy neutron
174       simulation. for details see:
175       http://www.staff.uni-mainz.de/zeitnitz/Gcalor/gcalor.html
176       This package should be distributed with the GEANT library but is
177       not up to date. I did download the latest release and stored into
178       gpcalor directory of the gpamela tree.
179       Then I did clean up the code substituting the explicit inclusion of
180       the commons with a #include cpp directive. In parallel I did
181       extract the commons to include files having the same common name. I
182       did store the include files into a newly created directory:
183       gpcalordes.
184       The Makefile has been updated accordingly.
185       Please note that to avoid conflict with CRENLIB distribution the gcalor source file has been named gpcalor.F
186       NOTE: There are still problem due to different common sizes. In
187       particular the common MICFIL is maller in the geant library
188       libgeant.a . There the subroutines: gmorin, gmxsec, gmplxs, are
189       present and linked using a wrong version of the common. This still needs to be debuged.
190       NOTE2: The auxiliary files with the cross sections: chetc.dat.gz
191       and xsneut.dat.gz, have been added to the aux directory and moved
192       to the working directory, i.e. GPAMELA_BIN. The GCALOR routine will
193       look for CERN_ROOT environment variable. If found files are
194       searched there at first, then in the working directory. A fool
195       proof policy has to be implemented to avoid problem with
196       synchronization fo these files.
197      
198    
199    The GCALOR package
200    
201    June 2005, Bari
202    
203    TOF SCINTILLATOR PADDLES UPDATED
204    
205       The dimensions and the number of the scintillator paddles for each
206       TOF planes have been updated.
207    
208    May 2005, Bari
209    
210    Some updates on the latest modification done in the past year.
211    
212    NEW DATA CARD ADDED: HFSF
213    
214       To define a policy for the random number initial seeds
215       definition. Using this card is possible to override GEANT seeds
216       defined via NRDM card. The policy is selected according to the
217       values:
218    
219       - 1: The seeds are initialized to the initial values found in a user
220            defined file or the default file: INPUTSEED.DAT
221      
222       - 2: The seeds are initialized to the final values found in a user defined
223            file or the default file: INPUTSEED.DAT
224    
225       The case 1 must be used in case the user needs to reproduce the
226       random chain of a previous run. In this case the user can save the
227       initial seeds, used in the run he would like to reproduce, in a
228       binary file and pass the filename to the program using the *FLSF
229       data card. In case the user file is not specified the default
230       INPUTSEED.DAT will be used.
231      
232       The case 2 must be used in case the user needs to chain several
233       GPAMELA run and likes to be sure he is starting the random
234       generator using the right sequence. In this case the user must
235       specify an input binary file using the *FLSF data card, otherwise
236       the INPUTSEED.DAT file will be used.
237    
238    NEW DATA CARD ADDED: *FSFI
239    
240       Using this card the user can specify the logical unit and name of
241       the file storing the initial seeds to be used to initialize the
242       random number generator. This file must be a FORTRAN binary one
243       storing four integer numbers. The first two are the number to be
244       used in the case: HFSF=1, the other two will be used in the case:
245       HFSF=2. This file can be one created by GPAMELA or by the user
246       filled with his own seeds. For this purpose an utility program:
247       writeseeds.f, has been added in the aux directory.  In case the
248       *FSFI card is not specified the default values: 24 and INPUTSEEDS.DAT, will
249       be used as LUN and file name respectively.
250      
251    NEW DATA CARD ADDED: *LSFI
252    
253       Using this card the user can specify the logical unit and name of
254       the file storing the first and last seeds used in the GPAMELA
255       run. This file is a FORTRAN binary one. This file can be used as
256       input one specifying it in the *FSFI data card of the next GPAMELA
257       run.  In case the *LSFI card is not specified the default values: 26
258       and HBOOKFILENAME.DAT (as sepified in *HFI), will be used as LUN
259       and file name respectively.
260      
261    NEW UTILITY PROGRAMS ADDED: writeseeds.f, readseeds.f
262    
263       These new programs have been added in the aux directory. Using these a
264       user defined seed file can be created and re-read.
265    
266    NEW VOLUMES ADDED: MSHE, BSPH; PRESSURIZED CONTAINER ADDED
267    
268       Alexey Bakaldin, in MEPHI, did add the PAMELA pressurized container to
269       the simulation. He did defined new volumes filled with aluminum and
270       placed inside the mother volume. Positions have been fine tuned by
271       Marialuigia Ambriola and compared to the CAD drawings.
272       Two new volumes have been added to simulate the container:
273       - MSHE, a tube simulating the middle part of the container
274       - BSPH, the spherical bottom part of the container
275    
276       To better simulate the upper part the SHEL volume has been modified
277       into a cone. Dimentions of the top cover: TSPH, have been modified
278       accordingly.
279    
280    DETECTOR POSITIONS REVIEWED
281    
282       All detector Z positions have been reviewd to fit into the
283       simulated pressurized container.
284    
285    TRD GEOMETRY AND CALIBRATION REVIEWD
286    
287       The TRD geometry has been deeply reviewed. Using the CAD drawings
288       the carbon fiber frames have been simulated and radiator dimentions
289       corrected. For this reason the calibration done on the beam tests
290       has been revied and new sets of calibration constants calculated
291       comparing the beam test data with the GPAMELA results. The new
292       constants are about 3% larger than the previous ones.
293      
294    TRACKER GEOMETRY REVIEWED. NEW VOLUME DEFINED: THBP, TPAS, TPAI
295      
296       Thanks to Lorenzo Bonechi for the drawings and explanations. Now the
297       hybrd cards have been put into the simulation and the geometry updated
298       considering the dead zones in the silicon detectors. The hybrid zone
299       has been simulated as well. At the moment the hybrid is simulated as
300       a G10 plates. The full height of the tracker magnet has been
301       reviewed as well.
302    
303       The tracker ladder is now simulated inside a nitrogen box: TPAS,
304       placed inside an aluminum frame: TRPB. Each silicon ladder has been
305       simulated using two silicon blocks: TRSL, into each of this block a
306       smaller silicon detector: TPAI, has been placed inside the larger
307       silicon block TRSL. In this way the subdivided silicon ladder can
308       be upgraded with an indipendend roto-translation for each sensor.
309      
310       The TRPB aluminum frame has been enlarged to fit the external
311       magnet canister frame.
312      
313       The last plane has been flipped with a 180 degree rotation around
314       the X axis.
315      
316    TRACKER HIT STRUCTURE REVIEWED
317    
318       Taking into account the new version of the tracker geometry, the hit
319       structure for this detector has been revied.
320    
321    CALORIMETER GEOMETRY REVIEWED
322    
323       Marco Albi reviewed the calorimeter dimentions and positioning.
324    
325    
326    29 March 2004, Bari
327    
328    NON-REPRODUCIBILITY PROBLEM OF A GPAMELA RUN FIXED.
329       The non-reproducibility of a GPAMELA run was due to the random number
330       initialization in the GARFIELD code. In GARFIELD by default, the initial
331       seeds of the random number generators are always the same while the random
332       number generators are called a given number of times (determined by the
333       hour of the day) during the initialization phase (see init.f subroutine in
334       the GARFIELD code for details). Follows that different runs produce
335       different results without changing the initial seeds. To have identical
336       results in different runs, the GARFIELD program has to start typing the
337       noRNDM_initialisation switch. To avoid of specifying this switch
338       by the user,
339       the GARFIELD package has been upgraded with a patch. In this way the problem
340       is partially solved because, now, the initial seeds of the random generators
341       in GARFIELD will be always the same even if the RNDM GEANT data card is
342       activated by the user for changing the initial seeds in the GPAMELA program.
343       Work is in progress for a more general correction of this problem.
344       Please, use the updated GARFIELD code released with the CVS version v4r1
345       to fix this problem.  
346    
347    
348    RNDM ROUTINE REPLACED BY THE GRNDM ROUTINE IN GPXTR AND NPOISS.
349       The obsolete RNDM random number generator has been replaced by the GEANT
350       GRNDN routine in the gpxtr.F subroutine and in the npoiss.F function.
351    
352    BUG FOUND AND FIXED: the set and detector calorimeter addresses (ISCAL
353       and IDCASI variables) used in GUTREV were respectively set to a fixed
354       values of 12 and 1. The correct values of these variables are stored in
355       the GPSED common when the set and the detector ZEBRA banks are filled
356       during a run. In general the values of the set and detector addresses
357       depend on the number of active detectors in a given run. ISCAL=12 and
358       IDCASI=1 are only right when all the detectors of GPAMELA are active.
359    
360    9 December 2003, Bari
361    
362       CALORIMETER SIMULATION completed! The update of the geometry and of the
363       special tracking parameters and the tuning of the calorimeter have been
364       successfully done. A great quantity of simulated data have been produced
365       in the calorimeter for different particles (muons, electrons and pions)
366       and momenta (5 and 40 GeV/c) and the output data have been analyzed. The
367       distributions of the total energy deposited in the calorimeter and the
368       total number of strips hit have been compared with the respective
369       distributions produced by the Trieste's tuned standalone Monte Carlo
370       simulation program of the PAMELA calorimeter. The accord between the
371       two simulations is excellent. Many thanks to Mirko for his collaboration.
372    
373       Working in progress on TRD. The GARFIELD interface to the HEED program is not
374       optimized to track particle with a charge greater than one and photons. The
375       program print a warning message to advise the user when it is the case.
376    
377    18 April 2003, Bari
378    
379       The buffer size of each column of the GPAMELA Ntuple has been increased to
380       4096 and set equal to the record length, defined by a call to the HROPEN
381       routine.
382       Also the length of the common /PAWC/ (parameter NWPAW) has been increased
383       to 1.34E8, according to the rule that it has to be larger than the number
384       of columns times the buffer size.
385    
386    10 April 2003, Bari
387    
388       The variables in the HIT STRUCTURE of the CALORIMETER and their way to be
389       filled have been changed according to the electronics system of the real
390       detector. In fact, because each silicon detector (module) consists of
391       32 strips and each strip is connected to those belonging to the two detectors
392       of the same row (or column) for forming 24 cm long strips, the sum of the
393       deposited energies in the strips forming a `long strip' is now calculated for
394       each event (gpucal.F subroutine) and it is stored in a hit only at the
395       end of the event (gutrev.F subroutine).
396       The output variables of the GPAMELA en-tuple are then filled in the vectors
397       ICAPLANE(NTHCAL), ICASTRIP(NTHCAL), ENESTRIP(NTHCAL) and ICAMOD(NTHCAL),
398       by a call to the GPDCAL subroutine:
399       -ICAPLANE(i) contains the number of hit plane;
400       -ICASTRIP(i) contains the number of hit strip;
401       -ICAMOD(i) can assume different values based on the number of times and
402                  positions in which a `long strip' has been hit.
403       -ENESTRIP(i) contains the deposited energy in the hit strip;
404       where i is the number of hit (1<i<4224).
405       Note that in the calorimeter each hit is filled at the end of the event and
406       that there is a hit for each `long strip' hit from
407       the particle. This use of the hit structure is different for the other
408       detectors and it has been considered to avoid a too big number of hit in the
409       calorimeter due to the showers. Follows that NTHCAL, which is the
410       max number of hit in the calorimeter, is equal to 4224, the total
411       number of `long strips'. So, for each event, the real number of hit will
412       be less or equal to 4224.
413       ICAMOD(i) is an additional information that does not exist in the real
414       detector: if the strip i (i=1,32) of the module 1 or 2 or 3
415       is hit, the value of ICAMOD(i) is respectively incremented of 1, 100, 10000.
416       Analogously it is done, if it is the strip j (j=33,64) of the modules 4, 5
417       and 6 or if it is the strip k (k=65,96) of the modules 7, 8 and 9.
418       For example if we consider the hit 1 of an event, we could read:
419       ICASTRIP(1)=30, ICAPLANE(1)=21, ENESTRIP(1)=0.5E-03 and ICAMOD(1)=10001.
420       It means that the hit 1 contains the information that in the strip 30 of the
421       plane 21 has been deposited a total energy of 0.5E-03 GeV. In addition the
422       `long strip 30' has been hit two times, one in the first module and the
423       other in the third one.
424    
425       The energy deposited in the calorimeter is calculated in GeV.
426    
427       To store the hits in the calorimeter the subroutine GSAHIT is used instead of
428       GSCHIT.
429    
430       To retrieve the hit structure the call to the routine GPRHIT is done instead
431       of a call to the GFHITS subroutine.
