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.
