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.
