70    November 2006, Bari
71    
72    TOF POSITIONS DEFINITELY UPDATED:
73    S2 and S1 have been positioned again, after the simulation of the top plate.
74    Before now, the positions were put ad hoc based on the positions given by
75    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
76    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
77    S. Ricciarini on the 20th of December 2005.. These positions were
78    lightly approximated.
79    
80    ND GEOMETRY COMPLETED.
81    The He3 and the polyethylene (CH2) have been added to fill
82    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
83    details of these materials.
84    
85    TOP PLATE GEOMETRY ADDED.
86    The top plate geometry has been simulated as a N2 box that has the same
87    dimensions of CATA. Inside it, at the right positions, there are S2 and CATA.
88    The real top plate is a rectangular window having a thickness of 0.5 cm
89    (volume TPTL emptied by the volume TPCV). This volume is filled with a mixture
90    of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium
91    are the four volumes TPTU, which are positioned at the corners of TPTL at the
92    same height of CATA, and the four volumes TPTM, which are positioned at the
93    corners of TPTL, at the same height of S2.
94    The geometry  of the top plate is based on a simplified version of the CAD
95    drawings.
96    
97    October 2006, Bari
98    
99    The geometry of the neutron detector has been updated. Some dimensions of some
100    volumes have been corrected and the aluminum cover and the aluminum boxes to
101    put the cables have been added. A new material, the cadmium, has been also
102    defined.
103    
104    September 2006, Bari
105    
106    SPHE and ND data card bugs fixed: the definition of the ND data card,
107    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
108    data card has been changed. Before the correction the data card:
109    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
110    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
111    
112    
113    June 2006, Bari
114    
115    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
116    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
117    nominal height as measured in PAMELA (See the document: "Main geometrical
118    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
119    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
120    of S21Y and S12X are higher than those in the cited document due to the fact
121    that in GPAMELA the thickness of the mylar has been considered while in the
122    document it has been neglected.
123    
124    
125    May 2006, Bari & Tor Vergata
126    
127    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
128    
129       Routines to simulate the gigantic resonance of gammas in Tungsten
130       have been added.  The GPGIG routine is called in GUSTEP if a gamma
131       enter the calorimeter absorber.  This is the steering routine to
132       simulate the production of neutrons from gigantic resonance.  It
133       does checks on STEP lenght. If the range is smaller than the other
134       selected for that step, it does generate the neutron and stops the
135       gamma. Please note that the neutron has now a new particle
136       number. This is to tag the gigantic resonance neutrons.
137    
138    
139    May 2006, Bari & Florence
140    
141    CAL HIT STRUCTURE BUGS FIXED
142    
143       The maximum number of hit is now different for the two hit
144       structures: CALST and CALI. Vectors inizialization and HBOOK
145       ntple booking have been updated. The GPDCAL routine has been fixed
146       so to handle the case in wich hits stored are more than the maximum
147       number of hit.
148       In this case in the ntple up to the maximum number of hits will be stored.
149    
150    April 2006, Bari
151    
152    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
153    
154       The TOF geometry has been modified. The following boxes have been
155       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
156       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
157       S1 and S2 made of aluminum. Each scintillator paddle has been put
158       in his mylar box and the other materials: air, polystyrene, and
159       aluminum have been added at their nominal positions.  According to
160       Naples people the araldite glue has been simulated has an air
161       gap. For this work two new materials: the Mylar (MYLAR) and the
162       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
163       defined as a mixture.  The positions of the three bottom
164       scintillator planes that contain respectively the S12X, S22Y and
165       S32X paddles have been regulated according on their official
166       positions in PAMELA.
167    
168    Mar 2006, Bari
169    
170    GEN DATA CARD UPDATED
171    
172       To enable generation on a surface perpendicular to the XY plane,
173       GEN gata card has been updated addingh a new parameter: ZDGEN. This is
174       the dimension, along Z axis , of the generation surface. The Z
175       position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER +
176       ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3).
