79    November 2006, Bari
80    
81    
82    S4 GEOMETRY UPDATED:
83    The x and y dimensions have been corrected because they were wrong.
84    A container of aluminum has been added having walls of thickness equal
85    to 0.1 cm.  
86    
87    TOF POSITIONS DEFINITELY UPDATED:
88    S2 and S1 have been positioned again, after the simulation of the top plate.
89    Before now, the positions were put by hand based on the positions given by
90    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
91    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
92    S. Ricciarini on the 20th of December 2005.. These positions were
93    lightly approximated because the thicknesses of the mylar and of the glue were
94    not considered in that document. Also the height of S3 has been modified as
95    suggested from the Naples PAMELA collaborators.
96    
97    ND GEOMETRY COMPLETED.
98    The He3 and the polyethylene (CH2) have been added to fill
99    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
100    details of these materials.
101    
102    TOP PLATE GEOMETRY ADDED.
103    The top plate geometry has been simulated as a N2 box that has the same
104    dimensions of CATA. Inside it, at the right positions, there are S2 and CATA.
105    The real top plate is a rectangular window having a thickness of 0.5 cm
106    (volume TPTL emptied by the volume TPCV). This volume is filled with a mixture
107    of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium
108    are the four volumes TPTU, which are positioned at the corners of TPTL at the
109    same height of CATA, and the four volumes TPTM, which are positioned at the
110    corners of TPTL, at the same height of S2.
111    The geometry  of the top plate is based on a simplified version of the CAD
112    drawings.
113    
114    October 2006, Bari
115    
116    The geometry of the neutron detector has been updated. Some dimensions of some
117    volumes have been corrected and the aluminum cover and the aluminum boxes to
118    put the cables have been added. A new material, the cadmium, has been also
119    defined.
120    
121    September 2006, Bari
122    
123    SPHE and ND data card bugs fixed: the definition of the ND data card,
124    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
125    data card has been changed. Before the correction the data card:
126    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
127    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
128    
129    
130    June 2006, Bari
131    
132    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
133    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
134    nominal height as measured in PAMELA (See the document: "Main geometrical
135    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
136    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
137    of S21Y and S12X are higher than those in the cited document due to the fact
138    that in GPAMELA the thickness of the mylar has been considered while in the
139    document it has been neglected.
140    
141    
142    May 2006, Bari & Tor Vergata
143    
144    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
145    
146       Routines to simulate the gigantic resonance of gammas in Tungsten
147       have been added.  The GPGIG routine is called in GUSTEP if a gamma
148       enter the calorimeter absorber.  This is the steering routine to
149       simulate the production of neutrons from gigantic resonance.  It
150       does checks on STEP lenght. If the range is smaller than the other
151       selected for that step, it does generate the neutron and stops the
152       gamma. Please note that the neutron has now a new particle
153       number. This is to tag the gigantic resonance neutrons.
154    
155    
156    May 2006, Bari & Florence
157    
158    CAL HIT STRUCTURE BUGS FIXED
159    
160       The maximum number of hit is now different for the two hit
161       structures: CALST and CALI. Vectors inizialization and HBOOK
162       ntple booking have been updated. The GPDCAL routine has been fixed
163       so to handle the case in wich hits stored are more than the maximum
164       number of hit.
165       In this case in the ntple up to the maximum number of hits will be stored.
166    
167    April 2006, Bari
168    
169    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
170    
171       The TOF geometry has been modified. The following boxes have been
172       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
173       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
174       S1 and S2 made of aluminum. Each scintillator paddle has been put
175       in his mylar box and the other materials: air, polystyrene, and
176       aluminum have been added at their nominal positions.  According to
177       Naples people the araldite glue has been simulated has an air
178       gap. For this work two new materials: the Mylar (MYLAR) and the
179       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
180       defined as a mixture.  The positions of the three bottom
181       scintillator planes that contain respectively the S12X, S22Y and
182       S32X paddles have been regulated according on their official
183       positions in PAMELA.
184    
185    Mar 2006, Bari
186    
187    GEN DATA CARD UPDATED
188    
189       To enable generation on a surface perpendicular to the XY plane,
190       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
191       the dimension, along Z axis , of the generation surface. The Z
192       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
193       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).
194    
195    Nov 2005, Bari
196    
197    GUHADR AND GUPHAD UPDATED
198    
199       To use GCALOR package the hadronic routines have been updated. The
200       inizialization routine call CALSIG, while the other calls GCALOR.
201    
202    NEW GPKEY ADDED: GPCALOR
203    
204       This logical has been added to enable the GCALOR package. This flag
205       is set to true in GPDAT if the data card: HPAK, is set to
206       'GCAL'. The gpkey.inc has been update accordingly.
207    
208      
209    NEUTRON DETECTOR ADDED. NEW DIR: GPND
210    
211       The neutron detector has been added. At the moment it is just the
212       geometry. The directory structure of the repository has been
213       updated as well. Dimensions has been taken from picture and
214       literature. A full upgrade to the drawing is needed.
215    
216    GCALOR PACKAGE ADDED. NEW DIRs: GPCALOR, GPCALORDES
217    
218       GCALOR package contins the CALOR simulation code and an interface
219       to use it in GEANT. The important feature for us is the usage of
220       the MICAP code. This is facused on the low energy neutron
221       simulation. for details see:
222       http://www.staff.uni-mainz.de/zeitnitz/Gcalor/gcalor.html
223       This package should be distributed with the GEANT library but is
224       not up to date. I did download the latest release and stored into
225       gpcalor directory of the gpamela tree.
226       Then I did clean up the code substituting the explicit inclusion of
227       the commons with a #include cpp directive. In parallel I did
228       extract the commons to include files having the same common name. I
229       did store the include files into a newly created directory:
230       gpcalordes.
231       The Makefile has been updated accordingly.
232       Please note that to avoid conflict with CRENLIB distribution the gcalor source file has been named gpcalor.F
233       NOTE: There are still problem due to different common sizes. In
234       particular the common MICFIL is maller in the geant library
235       libgeant.a . There the subroutines: gmorin, gmxsec, gmplxs, are
236       present and linked using a wrong version of the common. This still needs to be debuged.
237       NOTE2: The auxiliary files with the cross sections: chetc.dat.gz
238       and xsneut.dat.gz, have been added to the aux directory and moved
239       to the working directory, i.e. GPAMELA_BIN. The GCALOR routine will
240       look for CERN_ROOT environment variable. If found files are
241       searched there at first, then in the working directory. A fool
242       proof policy has to be implemented to avoid problem with
243       synchronization fo these files.
244      
245    
246    The GCALOR package
247    
248    June 2005, Bari
249    
250    TOF SCINTILLATOR PADDLES UPDATED
251    
252       The dimensions and the number of the scintillator paddles for each
253       TOF planes have been updated.
