82    December 2006, Bari
83    
84    CARD GEOMETRY:
85    Positions, dimensions and quotes have been updated. Indeed, the aluminium table
86    under S1, legs included, and the magnetic screen between the CARD and S2 have
87    been added.
88    
89    #-------------------------------------------------------------------------
90    
91    November 2006, Bari
92    
93    
94    S4 GEOMETRY UPDATED:
95    The x and y dimensions have been corrected because they were wrong.
96    A container of aluminum has been added having walls of thickness equal
97    to 0.1 cm.
98    
99    TOF POSITIONS DEFINITELY UPDATED:
100    S2 and S1 have been positioned again, after the simulation of the top plate.
101    Before now, the positions were put ad hoc based on the positions given by
102    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
103    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
104    S. Ricciarini on the 20th of December 2005.. These positions were
105    lightly approximated.
106    
107    ND GEOMETRY COMPLETED.
108    The He3 and the polyethylene (CH2) have been added to fill
109    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
110    details of these materials.
111    
112    TOP PLATE GEOMETRY ADDED.
113    The top plate geometry has been simulated as a N2 box that has the same
114    dimensions of CATA. Inside it, at the right positions, there are S2 and CATA.
115    The real top plate is a rectangular window having a thickness of 0.5 cm
116    (volume TPTL emptied by the volume TPCV). This volume is filled with a mixture
117    of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium
118    are the four volumes TPTU, which are positioned at the corners of TPTL at the
119    same height of CATA, and the four volumes TPTM, which are positioned at the
120    corners of TPTL, at the same height of S2.
121    The geometry  of the top plate is based on a simplified version of the CAD
122    drawings.
123    
124    October 2006, Bari
125    
126    The geometry of the neutron detector has been updated. Some dimensions of some
127    volumes have been corrected and the aluminum cover and the aluminum boxes to
128    put the cables have been added. A new material, the cadmium, has been also
129    defined.
130    
131    September 2006, Bari
132    
133    SPHE and ND data card bugs fixed: the definition of the ND data card,
134    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
135    data card has been changed. Before the correction the data card:
136    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
137    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
138    
139    
140    June 2006, Bari
141    
142    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
143    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
144    nominal height as measured in PAMELA (See the document: "Main geometrical
145    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
146    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
147    of S21Y and S12X are higher than those in the cited document due to the fact
148    that in GPAMELA the thickness of the mylar has been considered while in the
149    document it has been neglected.
150    
151    
152    May 2006, Bari & Tor Vergata
153    
154    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
155    
156       Routines to simulate the gigantic resonance of gammas in Tungsten
157       have been added.  The GPGIG routine is called in GUSTEP if a gamma
158       enter the calorimeter absorber.  This is the steering routine to
159       simulate the production of neutrons from gigantic resonance.  It
160       does checks on STEP lenght. If the range is smaller than the other
161       selected for that step, it does generate the neutron and stops the
162       gamma. Please note that the neutron has now a new particle
163       number. This is to tag the gigantic resonance neutrons.
164    
165    
166    May 2006, Bari & Florence
167    
168    CAL HIT STRUCTURE BUGS FIXED
169    
170       The maximum number of hit is now different for the two hit
171       structures: CALST and CALI. Vectors inizialization and HBOOK
172       ntple booking have been updated. The GPDCAL routine has been fixed
173       so to handle the case in wich hits stored are more than the maximum
174       number of hit.
175       In this case in the ntple up to the maximum number of hits will be stored.
176    
177    April 2006, Bari
178    
179    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
180    
181       The TOF geometry has been modified. The following boxes have been
182       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
183       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
184       S1 and S2 made of aluminum. Each scintillator paddle has been put
185       in his mylar box and the other materials: air, polystyrene, and
186       aluminum have been added at their nominal positions.  According to
187       Naples people the araldite glue has been simulated has an air
188       gap. For this work two new materials: the Mylar (MYLAR) and the
189       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
190       defined as a mixture.  The positions of the three bottom
191       scintillator planes that contain respectively the S12X, S22Y and
192       S32X paddles have been regulated according on their official
193       positions in PAMELA.
194    
195    Mar 2006, Bari
196    
197    GEN DATA CARD UPDATED
198    
199       To enable generation on a surface perpendicular to the XY plane,
200       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
201       the dimension, along Z axis , of the generation surface. The Z
202       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
203       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).
204    
205    Nov 2005, Bari
206    
207    GUHADR AND GUPHAD UPDATED
208    
209       To use GCALOR package the hadronic routines have been updated. The
210       inizialization routine call CALSIG, while the other calls GCALOR.
211    
212    NEW GPKEY ADDED: GPCALOR
213    
214       This logical has been added to enable the GCALOR package. This flag
215       is set to true in GPDAT if the data card: HPAK, is set to
216       'GCAL'. The gpkey.inc has been update accordingly.
217    
218    
219    NEUTRON DETECTOR ADDED. NEW DIR: GPND
220    
221       The neutron detector has been added. At the moment it is just the
222       geometry. The directory structure of the repository has been
223       updated as well. Dimensions has been taken from picture and
224       literature. A full upgrade to the drawing is needed.
225    
226    GCALOR PACKAGE ADDED. NEW DIRs: GPCALOR, GPCALORDES
227    
228       GCALOR package contins the CALOR simulation code and an interface
229       to use it in GEANT. The important feature for us is the usage of
230       the MICAP code. This is facused on the low energy neutron
231       simulation. for details see:
232       http://www.staff.uni-mainz.de/zeitnitz/Gcalor/gcalor.html
233       This package should be distributed with the GEANT library but is
234       not up to date. I did download the latest release and stored into
235       gpcalor directory of the gpamela tree.
236       Then I did clean up the code substituting the explicit inclusion of
237       the commons with a #include cpp directive. In parallel I did
238       extract the commons to include files having the same common name. I
239       did store the include files into a newly created directory:
240       gpcalordes.
241       The Makefile has been updated accordingly.
242       Please note that to avoid conflict with CRENLIB distribution the gcalor source file has been named gpcalor.F
243       NOTE: There are still problem due to different common sizes. In
244       particular the common MICFIL is maller in the geant library
245       libgeant.a . There the subroutines: gmorin, gmxsec, gmplxs, are
246       present and linked using a wrong version of the common. This still needs to be debuged.
247       NOTE2: The auxiliary files with the cross sections: chetc.dat.gz
248       and xsneut.dat.gz, have been added to the aux directory and moved
249       to the working directory, i.e. GPAMELA_BIN. The GCALOR routine will
250       look for CERN_ROOT environment variable. If found files are
251       searched there at first, then in the working directory. A fool
252       proof policy has to be implemented to avoid problem with
253       synchronization fo these files.
254    
255    
256    The GCALOR package
257    
258    June 2005, Bari
259    
260    TOF SCINTILLATOR PADDLES UPDATED
261    
262       The dimensions and the number of the scintillator paddles for each
263       TOF planes have been updated.
264    
265    May 2005, Bari
266    
267    Some updates on the latest modification done in the past year.
268    
269    NEW DATA CARD ADDED: HFSF
270    
271       To define a policy for the random number initial seeds
272       definition. Using this card is possible to override GEANT seeds
273       defined via NRDM card. The policy is selected according to the
274       values:
275    
276       - 1: The seeds are initialized to the initial values found in a user
277            defined file or the default file: INPUTSEED.DAT
278    
279       - 2: The seeds are initialized to the final values found in a user defined
280            file or the default file: INPUTSEED.DAT
281    
282       The case 1 must be used in case the user needs to reproduce the
283       random chain of a previous run. In this case the user can save the
284       initial seeds, used in the run he would like to reproduce, in a
285       binary file and pass the filename to the program using the *FLSF
286       data card. In case the user file is not specified the default
287       INPUTSEED.DAT will be used.
288    
289       The case 2 must be used in case the user needs to chain several
290       GPAMELA run and likes to be sure he is starting the random
291       generator using the right sequence. In this case the user must
292       specify an input binary file using the *FLSF data card, otherwise
293       the INPUTSEED.DAT file will be used.
294    
295    NEW DATA CARD ADDED: *FSFI
296    
297       Using this card the user can specify the logical unit and name of
298       the file storing the initial seeds to be used to initialize the
299       random number generator. This file must be a FORTRAN binary one
300       storing four integer numbers. The first two are the number to be
301       used in the case: HFSF=1, the other two will be used in the case:
302       HFSF=2. This file can be one created by GPAMELA or by the user
303       filled with his own seeds. For this purpose an utility program:
304       writeseeds.f, has been added in the aux directory.  In case the
305       *FSFI card is not specified the default values: 24 and INPUTSEEDS.DAT, will
306       be used as LUN and file name respectively.
307    
308    NEW DATA CARD ADDED: *LSFI
309    
310       Using this card the user can specify the logical unit and name of
311       the file storing the first and last seeds used in the GPAMELA
312       run. This file is a FORTRAN binary one. This file can be used as
313       input one specifying it in the *FSFI data card of the next GPAMELA
314       run.  In case the *LSFI card is not specified the default values: 26
315       and HBOOKFILENAME.DAT (as sepified in *HFI), will be used as LUN
316       and file name respectively.
317    
318    NEW UTILITY PROGRAMS ADDED: writeseeds.f, readseeds.f
319    
320       These new programs have been added in the aux directory. Using these a
321       user defined seed file can be created and re-read.
322    
323    NEW VOLUMES ADDED: MSHE, BSPH; PRESSURIZED CONTAINER ADDED
324    
325       Alexey Bakaldin, in MEPHI, did add the PAMELA pressurized container to
326       the simulation. He did defined new volumes filled with aluminum and
327       placed inside the mother volume. Positions have been fine tuned by
328       Marialuigia Ambriola and compared to the CAD drawings.
329       Two new volumes have been added to simulate the container:
330       - MSHE, a tube simulating the middle part of the container
331       - BSPH, the spherical bottom part of the container
332    
333       To better simulate the upper part the SHEL volume has been modified
334       into a cone. Dimentions of the top cover: TSPH, have been modified
335       accordingly.
336    
337    DETECTOR POSITIONS REVIEWED
338    
339       All detector Z positions have been reviewd to fit into the
340       simulated pressurized container.
341    
342    TRD GEOMETRY AND CALIBRATION REVIEWD
343    
344       The TRD geometry has been deeply reviewed. Using the CAD drawings
345       the carbon fiber frames have been simulated and radiator dimentions
346       corrected. For this reason the calibration done on the beam tests
347       has been revied and new sets of calibration constants calculated
348       comparing the beam test data with the GPAMELA results. The new
349       constants are about 3% larger than the previous ones.
350    
351    TRACKER GEOMETRY REVIEWED. NEW VOLUME DEFINED: THBP, TPAS, TPAI
352    
353       Thanks to Lorenzo Bonechi for the drawings and explanations. Now the
354       hybrd cards have been put into the simulation and the geometry updated
355       considering the dead zones in the silicon detectors. The hybrid zone
356       has been simulated as well. At the moment the hybrid is simulated as
357       a G10 plates. The full height of the tracker magnet has been
358       reviewed as well.
359    
360       The tracker ladder is now simulated inside a nitrogen box: TPAS,
361       placed inside an aluminum frame: TRPB. Each silicon ladder has been
362       simulated using two silicon blocks: TRSL, into each of this block a
363       smaller silicon detector: TPAI, has been placed inside the larger
364       silicon block TRSL. In this way the subdivided silicon ladder can
365       be upgraded with an indipendend roto-translation for each sensor.
366    
367       The TRPB aluminum frame has been enlarged to fit the external
368       magnet canister frame.
369    
370       The last plane has been flipped with a 180 degree rotation around
371       the X axis.
372    
373    TRACKER HIT STRUCTURE REVIEWED
374    
375       Taking into account the new version of the tracker geometry, the hit
376       structure for this detector has been revied.
377    
378    CALORIMETER GEOMETRY REVIEWED
379    
380       Marco Albi reviewed the calorimeter dimentions and positioning.
381    
382    
383    29 March 2004, Bari
384    
385    NON-REPRODUCIBILITY PROBLEM OF A GPAMELA RUN FIXED.
386       The non-reproducibility of a GPAMELA run was due to the random number
387       initialization in the GARFIELD code. In GARFIELD by default, the initial
388       seeds of the random number generators are always the same while the random
389       number generators are called a given number of times (determined by the
390       hour of the day) during the initialization phase (see init.f subroutine in
391       the GARFIELD code for details). Follows that different runs produce
392       different results without changing the initial seeds. To have identical
393       results in different runs, the GARFIELD program has to start typing the
394       noRNDM_initialisation switch. To avoid of specifying this switch
395       by the user,
396       the GARFIELD package has been upgraded with a patch. In this way the problem
397       is partially solved because, now, the initial seeds of the random generators
398       in GARFIELD will be always the same even if the RNDM GEANT data card is
399       activated by the user for changing the initial seeds in the GPAMELA program.
400       Work is in progress for a more general correction of this problem.
401       Please, use the updated GARFIELD code released with the CVS version v4r1
402       to fix this problem.
403    
404    
405    RNDM ROUTINE REPLACED BY THE GRNDM ROUTINE IN GPXTR AND NPOISS.
406       The obsolete RNDM random number generator has been replaced by the GEANT
407       GRNDN routine in the gpxtr.F subroutine and in the npoiss.F function.
408    
409    BUG FOUND AND FIXED: the set and detector calorimeter addresses (ISCAL
410       and IDCASI variables) used in GUTREV were respectively set to a fixed
411       values of 12 and 1. The correct values of these variables are stored in
412       the GPSED common when the set and the detector ZEBRA banks are filled
413       during a run. In general the values of the set and detector addresses
414       depend on the number of active detectors in a given run. ISCAL=12 and
415       IDCASI=1 are only right when all the detectors of GPAMELA are active.
416    
417    9 December 2003, Bari
418    
419       CALORIMETER SIMULATION completed! The update of the geometry and of the
420       special tracking parameters and the tuning of the calorimeter have been
421       successfully done. A great quantity of simulated data have been produced
422       in the calorimeter for different particles (muons, electrons and pions)
423       and momenta (5 and 40 GeV/c) and the output data have been analyzed. The
424       distributions of the total energy deposited in the calorimeter and the
425       total number of strips hit have been compared with the respective
426       distributions produced by the Trieste's tuned standalone Monte Carlo
427       simulation program of the PAMELA calorimeter. The accord between the
428       two simulations is excellent. Many thanks to Mirko for his collaboration.

436       The buffer size of each column of the GPAMELA Ntuple has been increased to
437       4096 and set equal to the record length, defined by a call to the HROPEN
438       routine.
439       Also the length of the common /PAWC/ (parameter NWPAW) has been increased
440       to 1.34E8, according to the rule that it has to be larger than the number
441       of columns times the buffer size.

444    
445       The variables in the HIT STRUCTURE of the CALORIMETER and their way to be
446       filled have been changed according to the electronics system of the real
447       detector. In fact, because each silicon detector (module) consists of
448       32 strips and each strip is connected to those belonging to the two detectors
449       of the same row (or column) for forming 24 cm long strips, the sum of the
450       deposited energies in the strips forming a `long strip' is now calculated for
451       each event (gpucal.F subroutine) and it is stored in a hit only at the
452       end of the event (gutrev.F subroutine).
453       The output variables of the GPAMELA en-tuple are then filled in the vectors
454       ICAPLANE(NTHCAL), ICASTRIP(NTHCAL), ENESTRIP(NTHCAL) and ICAMOD(NTHCAL),
455       by a call to the GPDCAL subroutine:
456       -ICAPLANE(i) contains the number of hit plane;
457       -ICASTRIP(i) contains the number of hit strip;
458       -ICAMOD(i) can assume different values based on the number of times and
459              positions in which a `long strip' has been hit.
460       -ENESTRIP(i) contains the deposited energy in the hit strip;
461       where i is the number of hit (1<i<4224).
462       Note that in the calorimeter each hit is filled at the end of the event and
463       that there is a hit for each `long strip' hit from
464       the particle. This use of the hit structure is different for the other
465       detectors and it has been considered to avoid a too big number of hit in the
466       calorimeter due to the showers. Follows that NTHCAL, which is the
467       max number of hit in the calorimeter, is equal to 4224, the total
468       number of `long strips'. So, for each event, the real number of hit will
469       be less or equal to 4224.
470       ICAMOD(i) is an additional information that does not exist in the real
471       detector: if the strip i (i=1,32) of the module 1 or 2 or 3
472       is hit, the value of ICAMOD(i) is respectively incremented of 1, 100, 10000.
473       Analogously it is done, if it is the strip j (j=33,64) of the modules 4, 5
474       and 6 or if it is the strip k (k=65,96) of the modules 7, 8 and 9.
475       For example if we consider the hit 1 of an event, we could read:
476       ICASTRIP(1)=30, ICAPLANE(1)=21, ENESTRIP(1)=0.5E-03 and ICAMOD(1)=10001.
477       It means that the hit 1 contains the information that in the strip 30 of the
478       plane 21 has been deposited a total energy of 0.5E-03 GeV. In addition the
479       `long strip 30' has been hit two times, one in the first module and the
480       other in the third one.
481    
482       The energy deposited in the calorimeter is calculated in GeV.
483    
484       To store the hits in the calorimeter the subroutine GSAHIT is used instead of
485       GSCHIT.
486    
487       To retrieve the hit structure the call to the routine GPRHIT is done instead
488       of a call to the GFHITS subroutine.
