Adriani, L. Bonechi, E. Mocchiutti and +S. Ricciarini on the 20th of December 2005.. These positions were +lightly approximated. + +ND GEOMETRY COMPLETED. +The He3 and the polyethylene (CH2) have been added to fill +the volumes NDTI and NDPB in the neutron detector. Leonov gave us the +details of these materials. + +TOP PLATE GEOMETRY ADDED. +The top plate geometry has been simulated as a N2 box that has the same +dimensions of CATA. Inside it, at the right positions, there are S2 and CATA. +The real top plate is a rectangular window having a thickness of 0.5 cm +(volume TPTL emptied by the volume TPCV). This volume is filled with a mixture +of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium +are the four volumes TPTU, which are positioned at the corners of TPTL at the +same height of CATA, and the four volumes TPTM, which are positioned at the +corners of TPTL, at the same height of S2. +The geometry of the top plate is based on a simplified version of the CAD +drawings. + +October 2006, Bari + +The geometry of the neutron detector has been updated. Some dimensions of some +volumes have been corrected and the aluminum cover and the aluminum boxes to +put the cables have been added. A new material, the cadmium, has been also +defined. + +September 2006, Bari + +SPHE and ND data card bugs fixed: the definition of the ND data card, +missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE +data card has been changed. Before the correction the data card: +NDET 'SPHE' was used to delete the spherical top shell to substitute it with +a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA. + + +June 2006, Bari + +The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc) +and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the +nominal height as measured in PAMELA (See the document: "Main geometrical +parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi, +E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions +of S21Y and S12X are higher than those in the cited document due to the fact +that in GPAMELA the thickness of the mylar has been considered while in the +document it has been neglected. + + +May 2006, Bari & Tor Vergata + +GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED + + Routines to simulate the gigantic resonance of gammas in Tungsten + have been added. The GPGIG routine is called in GUSTEP if a gamma + enter the calorimeter absorber. This is the steering routine to + simulate the production of neutrons from gigantic resonance. It + does checks on STEP lenght. If the range is smaller than the other + selected for that step, it does generate the neutron and stops the + gamma. Please note that the neutron has now a new particle + number.

Vectors inizialization and HBOOK + ntple booking have been updated. The GPDCAL routine has been fixed + so to handle the case in wich hits stored are more than the maximum + number of hit. + In this case in the ntple up to the maximum number of hits will be stored. + +April 2006, Bari + +TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED + + The TOF geometry has been modified. The following boxes have been + added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M, + S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and + S1 and S2 made of aluminum. Each scintillator paddle has been put + in his mylar box and the other materials: air, polystyrene, and + aluminum have been added at their nominal positions. According to + Naples people the araldite glue has been simulated has an air + gap. For this work two new materials: the Mylar (MYLAR) and the + polystyrene (POLYSTYRENE) with a density of 35 g/l have been + defined as a mixture. The positions of the three bottom + scintillator planes that contain respectively the S12X, S22Y and + S32X paddles have been regulated according on their official + positions in PAMELA. + +Mar 2006, Bari + +GEN DATA CARD UPDATED + + To enable generation on a surface perpendicular to the XY plane, + GEN gata card has been updated addingh a new parameter: ZDGEN.
