81    
82    November 2006, Bari
83    
84    
85    S4 GEOMETRY UPDATED:
86    The x and y dimensions have been corrected because they were wrong.
87    A container of aluminum has been added having walls of thickness equal
88    to 0.1 cm.  
89    
90    TOF POSITIONS DEFINITELY UPDATED:
91    S2 and S1 have been positioned again, after the simulation of the top plate.
92    Before now, the positions were put by hand based on the positions given by
93    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
94    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
95    S. Ricciarini on the 20th of December 2005.. These positions were
96    lightly approximated because the thicknesses of the mylar and of the glue were
97    not considered in that document. Also the height of S3 has been modified as
98    suggested from the Naples PAMELA collaborators.
99    
100    ND GEOMETRY COMPLETED.
101    The He3 and the polyethylene (CH2) have been added to fill
102    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
103    details of these materials.
104    
105    TOP PLATE GEOMETRY ADDED.
106    The top plate geometry has been simulated as a rectangular window filled
107    with a mixture of titanium (90%), aluminum (6%) and vanadium (4%). It has been
108    put in a N2 box having the same planar dimensions of CATA. In this box there
109    are also S2 and CATA at the right positions. Then the top plate geometry has
110    been completed with other eight small volumes of titanium positioned at the
111    corners of the N2 box. Four of them are at the same height of CATA, the
112    other four are at the same height of S2. The simulated geometry of the top
113    plate is based on a simplified version of the CAD drawings.
114    
115    October 2006, Bari
116    
117    The geometry of the neutron detector has been updated. Some dimensions of some
118    volumes have been corrected and the aluminum cover and the aluminum boxes to
119    put the cables have been added. A new material, the cadmium, has been also
120    defined.
121    
122    September 2006, Bari
123    
124    SPHE and ND data card bugs fixed: the definition of the ND data card,
125    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
126    data card has been changed. Before the correction the data card:
127    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
128    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
129    
130    
131    June 2006, Bari
132    
133    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
134    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
135    nominal height as measured in PAMELA (See the document: "Main geometrical
136    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
137    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
138    of S21Y and S12X are higher than those in the cited document due to the fact
139    that in GPAMELA the thickness of the mylar has been considered while in the
140    document it has been neglected.
141    
142    
143    May 2006, Bari & Tor Vergata
144    
145    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
146    
147       Routines to simulate the gigantic resonance of gammas in Tungsten
148       have been added.  The GPGIG routine is called in GUSTEP if a gamma
149       enter the calorimeter absorber.  This is the steering routine to
150       simulate the production of neutrons from gigantic resonance.  It
151       does checks on STEP lenght. If the range is smaller than the other
152       selected for that step, it does generate the neutron and stops the
153       gamma. Please note that the neutron has now a new particle
154       number. This is to tag the gigantic resonance neutrons.

169    
170    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
171    
172       The TOF geometry has been modified. The following boxes have been
173       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
174       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
175       S1 and S2 made of aluminum. Each scintillator paddle has been put
176       in his mylar box and the other materials: air, polystyrene, and
177       aluminum have been added at their nominal positions.  According to
178       Naples people the araldite glue has been simulated has an air
179       gap. For this work two new materials: the Mylar (MYLAR) and the
180       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
181       defined as a mixture.  The positions of the three bottom
182       scintillator planes that contain respectively the S12X, S22Y and
183       S32X paddles have been regulated according on their official
184       positions in PAMELA.
