76    November 2006, Bari
77    
78    
79    S4 GEOMETRY UPDATED:
80    The x and y dimensions have been corrected because they were wrong.
81    A container of aluminum has been added having walls of thickness equal
82    to 0.1 cm.  
83    
84    TOF POSITIONS DEFINITELY UPDATED:
85    S2 and S1 have been positioned again, after the simulation of the top plate.
86    Before now, the positions were put ad hoc based on the positions given by
87    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
88    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
89    S. Ricciarini on the 20th of December 2005.. These positions were
90    lightly approximated.
91    
92    ND GEOMETRY COMPLETED.
93    The He3 and the polyethylene (CH2) have been added to fill
94    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
95    details of these materials.
96    
97    TOP PLATE GEOMETRY ADDED.
98    The top plate geometry has been simulated as a N2 box that has the same
99    dimensions of CATA. Inside it, at the right positions, there are S2 and CATA.
100    The real top plate is a rectangular window having a thickness of 0.5 cm
101    (volume TPTL emptied by the volume TPCV). This volume is filled with a mixture
102    of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium
103    are the four volumes TPTU, which are positioned at the corners of TPTL at the
104    same height of CATA, and the four volumes TPTM, which are positioned at the
105    corners of TPTL, at the same height of S2.
106    The geometry  of the top plate is based on a simplified version of the CAD
107    drawings.
108    
109    October 2006, Bari
110    
111    The geometry of the neutron detector has been updated. Some dimensions of some
112    volumes have been corrected and the aluminum cover and the aluminum boxes to
113    put the cables have been added. A new material, the cadmium, has been also
114    defined.
115    
116    September 2006, Bari
117    
118    SPHE and ND data card bugs fixed: the definition of the ND data card,
119    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
120    data card has been changed. Before the correction the data card:
121    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
122    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
123    
124    
125    June 2006, Bari
126    
127    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
128    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
129    nominal height as measured in PAMELA (See the document: "Main geometrical
130    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
131    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
132    of S21Y and S12X are higher than those in the cited document due to the fact
133    that in GPAMELA the thickness of the mylar has been considered while in the
134    document it has been neglected.
135    
136    
137    May 2006, Bari & Tor Vergata
138    
139    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
140    
141       Routines to simulate the gigantic resonance of gammas in Tungsten
142       have been added.  The GPGIG routine is called in GUSTEP if a gamma
143       enter the calorimeter absorber.  This is the steering routine to
144       simulate the production of neutrons from gigantic resonance.  It
145       does checks on STEP lenght. If the range is smaller than the other
146       selected for that step, it does generate the neutron and stops the
147       gamma. Please note that the neutron has now a new particle
148       number. This is to tag the gigantic resonance neutrons.
149    
150    
151    May 2006, Bari & Florence
152    
153    CAL HIT STRUCTURE BUGS FIXED
154    
155       The maximum number of hit is now different for the two hit
156       structures: CALST and CALI. Vectors inizialization and HBOOK
157       ntple booking have been updated. The GPDCAL routine has been fixed
158       so to handle the case in wich hits stored are more than the maximum
159       number of hit.
160       In this case in the ntple up to the maximum number of hits will be stored.
161    
162    April 2006, Bari
163    
164    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
165    
166       The TOF geometry has been modified. The following boxes have been
167       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
168       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
169       S1 and S2 made of aluminum. Each scintillator paddle has been put
170       in his mylar box and the other materials: air, polystyrene, and
171       aluminum have been added at their nominal positions.  According to
172       Naples people the araldite glue has been simulated has an air
173       gap. For this work two new materials: the Mylar (MYLAR) and the
174       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
175       defined as a mixture.  The positions of the three bottom
176       scintillator planes that contain respectively the S12X, S22Y and
177       S32X paddles have been regulated according on their official
178       positions in PAMELA.
179    
180    Mar 2006, Bari
181    
182    GEN DATA CARD UPDATED
183    
184       To enable generation on a surface perpendicular to the XY plane,
185       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
186       the dimension, along Z axis , of the generation surface. The Z
187       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
188       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).
