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