49    GEN DATA CARD UPDATED
50    
51       To enable generation on a surface perpendicular to the XY plane,
52       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
53       the dimension, along Z axis , of the generation surface. The Z
54       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
55       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).

57    Nov 2005, Bari
58    
59    GUHADR AND GUPHAD UPDATED
60    
61       To use GCALOR package the hadronic routines have been updated. The
62       inizialization routine call CALSIG, while the other calls GCALOR.
63    
64    NEW GPKEY ADDED: GPCALOR
65    
66       This logical has been added to enable the GCALOR package. This flag
67       is set to true in GPDAT if the data card: HPAK, is set to
68       'GCAL'. The gpkey.inc has been update accordingly.
69    
70      
71    NEUTRON DETECTOR ADDED. NEW DIR: GPND
72    
73       The neutron detector has been added. At the moment it is just the
74       geometry. The directory structure of the repository has been
75       updated as well. Dimensions has been taken from picture and
76       literature. A full upgrade to the drawing is needed.
77    
78    GCALOR PACKAGE ADDED. NEW DIRs: GPCALOR, GPCALORDES
79    
80       GCALOR package contins the CALOR simulation code and an interface
81       to use it in GEANT. The important feature for us is the usage of
82       the MICAP code. This is facused on the low energy neutron
83       simulation. for details see:
84       http://www.staff.uni-mainz.de/zeitnitz/Gcalor/gcalor.html
85       This package should be distributed with the GEANT library but is
86       not up to date. I did download the latest release and stored into
87       gpcalor directory of the gpamela tree.
88       Then I did clean up the code substituting the explicit inclusion of
89       the commons with a #include cpp directive. In parallel I did
90       extract the commons to include files having the same common name. I
91       did store the include files into a newly created directory:
92       gpcalordes.
93       The Makefile has been updated accordingly.
94       Please note that to avoid conflict with CRENLIB distribution the gcalor source file has been named gpcalor.F
95       NOTE: There are still problem due to different common sizes. In
96       particular the common MICFIL is maller in the geant library
97       libgeant.a . There the subroutines: gmorin, gmxsec, gmplxs, are
98       present and linked using a wrong version of the common. This still needs to be debuged.
99       NOTE2: The auxiliary files with the cross sections: chetc.dat.gz
100       and xsneut.dat.gz, have been added to the aux directory and moved
101       to the working directory, i.e. GPAMELA_BIN. The GCALOR routine will
102       look for CERN_ROOT environment variable. If found files are
103       searched there at first, then in the working directory. A fool
104       proof policy has to be implemented to avoid problem with
105       synchronization fo these files.
106      
107    
108    The GCALOR package
109    May 2005, Bari
110    
111    Some updates on the latest modification done in the past year.
112    
113    NEW DATA CARD ADDED: HFSF
114    
115       To define a policy for the random number initial seeds
116       definition. Using this card is possible to override GEANT seeds
117       defined via NRDM card. The policy is selected according to the
118       values:
119    
120       - 1: The seeds are initialized to the initial values found in a user
121            defined file or the default file: INPUTSEED.DAT
122      
123       - 2: The seeds are initialized to the final values found in a user defined
124            file or the default file: INPUTSEED.DAT
125    
126       The case 1 must be used in case the user needs to reproduce the
127       random chain of a previous run. In this case the user can save the
128       initial seeds, used in the run he would like to reproduce, in a
129       binary file and pass the filename to the program using the *FLSF
130       data card. In case the user file is not specified the default
131       INPUTSEED.DAT will be used.
132      
133       The case 2 must be used in case the user needs to chain several
134       GPAMELA run and likes to be sure he is starting the random
135       generator using the right sequence. In this case the user must
136       specify an input binary file using the *FLSF data card, otherwise
137       the INPUTSEED.DAT file will be used.
138    
139    NEW DATA CARD ADDED: *FSFI
140    
141       Using this card the user can specify the logical unit and name of
142       the file storing the initial seeds to be used to initialize the
143       random number generator. This file must be a FORTRAN binary one
144       storing four integer numbers. The first two are the number to be
145       used in the case: HFSF=1, the other two will be used in the case:
146       HFSF=2. This file can be one created by GPAMELA or by the user
147       filled with his own seeds. For this purpose an utility program:
148       writeseeds.f, has been added in the aux directory.  In case the
149       *FSFI card is not specified the default values: 24 and INPUTSEEDS.DAT, will
150       be used as LUN and file name respectively.
151      
152    NEW DATA CARD ADDED: *LSFI
153    
154       Using this card the user can specify the logical unit and name of
155       the file storing the first and last seeds used in the GPAMELA
156       run. This file is a FORTRAN binary one. This file can be used as
157       input one specifying it in the *FSFI data card of the next GPAMELA
158       run.  In case the *LSFI card is not specified the default values: 26
159       and HBOOKFILENAME.DAT (as sepified in *HFI), will be used as LUN
160       and file name respectively.
161      
162    NEW UTILITY PROGRAMS ADDED: writeseeds.f, readseeds.f
163    
164       These new programs have been added in the aux directory. Using these a
165       user defined seed file can be created and re-read.
166    
167    NEW VOLUMES ADDED: MSHE, BSPH; PRESSURIZED CONTAINER ADDED
168    
169       Alexey Bakaldin, in MEPHI, did add the PAMELA pressurized container to
170       the simulation. He did defined new volumes filled with aluminum and
171       placed inside the mother volume. Positions have been fine tuned by
172       Marialuigia Ambriola and compared to the CAD drawings.
173       Two new volumes have been added to simulate the container:
174       - MSHE, a tube simulating the middle part of the container
175       - BSPH, the spherical bottom part of the container
176    
177       To better simulate the upper part the SHEL volume has been modified
178       into a cone. Dimentions of the top cover: TSPH, have been modified
179       accordingly.
180    
181    DETECTOR POSITIONS REVIEWED
182    
183       All detector Z positions have been reviewd to fit into the
184       simulated pressurized container.
185    
186    TRD GEOMETRY AND CALIBRATION REVIEWD
187    
188       The TRD geometry has been deeply reviewed. Using the CAD drawings
189       the carbon fiber frames have been simulated and radiator dimentions
190       corrected. For this reason the calibration done on the beam tests
191       has been revied and new sets of calibration constants calculated
192       comparing the beam test data with the GPAMELA results. The new
193       constants are about 3% larger than the previous ones.
194      
195    TRACKER GEOMETRY REVIEWED. NEW VOLUME DEFINED: THBP, TPAS, TPAI
196      
197       Thanks to Lorenzo Bonechi for the drawings and explanations. Now the
198       hybrd cards have been put into the simulation and the geometry updated
199       considering the dead zones in the silicon detectors. The hybrid zone
200       has been simulated as well. At the moment the hybrid is simulated as
201       a G10 plates. The full height of the tracker magnet has been
202       reviewed as well.
203    
204       The tracker ladder is now simulated inside a nitrogen box: TPAS,
205       placed inside an aluminum frame: TRPB. Each silicon ladder has been
206       simulated using two silicon blocks: TRSL, into each of this block a
207       smaller silicon detector: TPAI, has been placed inside the larger
208       silicon block TRSL. In this way the subdivided silicon ladder can
209       be upgraded with an indipendend roto-translation for each sensor.
210      
211       The TRPB aluminum frame has been enlarged to fit the external
212       magnet canister frame.
213      
214       The last plane has been flipped with a 180 degree rotation around
215       the X axis.
216      
217    TRACKER HIT STRUCTURE REVIEWED
218    
219       Taking into account the new version of the tracker geometry, the hit
220       structure for this detector has been revied.
221    
222    CALORIMETER GEOMETRY REVIEWED
223    
224       Marco Albi reviewed the calorimeter dimentions and positioning.
