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
