86    
87    BUG FIXED
88    
89       For some reason there was a conflict using FLUKA and the GARFILD
90       interface for the TRD. The file TRD_ATT.TXT was treated as flukaerr
91       file by the compiler. It is not clear why. The code was correct,
92       the logical units and names were not inconflict, but the compiler
93       assigned to them the same internal number. It may be a problem
94       related to the optimization phase. I did close the file just after
95       the read-out in GPDAT.F and commented out the closing in UGLAST.F
96

100    
101    
102    S4 GEOMETRY UPDATED:
103    The x and y dimensions have been corrected because they were wrong.
104    A container of aluminum has been added having walls of thickness equal
105    to 0.1 cm.  
106    
107    TOF POSITIONS DEFINITELY UPDATED:
108    S2 and S1 have been positioned again, after the simulation of the top plate.
109    Before now, the positions were put by hand based on the positions given by
110    Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA
111    sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and
112    S. Ricciarini on the 20th of December 2005.. These positions were
113    lightly approximated because the thicknesses of the mylar and of the glue were
114    not considered in that document. Also the height of S3 has been modified as
115    suggested from the Naples PAMELA collaborators.
116    
117    ND GEOMETRY COMPLETED.
118    The He3 and the polyethylene (CH2) have been added to fill
119    the volumes NDTI and NDPB in the neutron detector. Leonov gave us the
120    details of these materials.
121    
122    TOP PLATE GEOMETRY ADDED.
123    The top plate geometry has been simulated as a rectangular window filled
124    with a mixture of titanium (90%), aluminum (6%) and vanadium (4%). It has been
125    put in a N2 box having the same planar dimensions of CATA. In this box there
126    are also S2 and CATA at the right positions. Then the top plate geometry has
127    been completed with other eight small volumes of titanium positioned at the
128    corners of the N2 box. Four of them are at the same height of CATA, the
129    other four are at the same height of S2. The simulated geometry of the top
130    plate is based on a simplified version of the CAD drawings.
131    
132    October 2006, Bari
133    
134    The geometry of the neutron detector has been updated. Some dimensions of some
135    volumes have been corrected and the aluminum cover and the aluminum boxes to
136    put the cables have been added. A new material, the cadmium, has been also
137    defined.
138    
139    September 2006, Bari
140    
141    SPHE and ND data card bugs fixed: the definition of the ND data card,
142    missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE
143    data card has been changed. Before the correction the data card:
144    NDET 'SPHE' was used to delete the spherical top shell to substitute it with
145    a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA.
146    
147    
148    June 2006, Bari
149    
150    The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc)
151    and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the
152    nominal height as measured in PAMELA (See the document: "Main geometrical
153    parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi,
154    E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions
155    of S21Y and S12X are higher than those in the cited document due to the fact
156    that in GPAMELA the thickness of the mylar has been considered while in the
157    document it has been neglected.
158    
159    
160    May 2006, Bari & Tor Vergata
161    
162    GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED
163    
164       Routines to simulate the gigantic resonance of gammas in Tungsten
165       have been added.  The GPGIG routine is called in GUSTEP if a gamma
166       enter the calorimeter absorber.  This is the steering routine to
167       simulate the production of neutrons from gigantic resonance.  It
168       does checks on STEP lenght. If the range is smaller than the other
169       selected for that step, it does generate the neutron and stops the
170       gamma. Please note that the neutron has now a new particle
171       number. This is to tag the gigantic resonance neutrons.

186    
187    TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED
188    
189       The TOF geometry has been modified. The following boxes have been
190       added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M,
191       S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and
192       S1 and S2 made of aluminum. Each scintillator paddle has been put
193       in his mylar box and the other materials: air, polystyrene, and
194       aluminum have been added at their nominal positions.  According to
195       Naples people the araldite glue has been simulated has an air
196       gap. For this work two new materials: the Mylar (MYLAR) and the
197       polystyrene (POLYSTYRENE) with a density of 35 g/l have been
198       defined as a mixture.  The positions of the three bottom
199       scintillator planes that contain respectively the S12X, S22Y and
200       S32X paddles have been regulated according on their official
201       positions in PAMELA.
