|
S4 GEOMETRY UPDATED: |
| 86 |
|
The x and y dimensions have been corrected because they were wrong. |
| 87 |
|
A container of aluminum has been added having walls of thickness equal |
| 88 |
|
to 0.1 cm. |
| 89 |
|
|
| 90 |
|
TOF POSITIONS DEFINITELY UPDATED: |
| 91 |
|
S2 and S1 have been positioned again, after the simulation of the top plate. |
| 92 |
|
Before now, the positions were put by hand based on the positions given by |
| 93 |
|
Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA |
| 94 |
|
sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and |
| 95 |
|
S. Ricciarini on the 20th of December 2005.. These positions were |
| 96 |
|
lightly approximated because the thicknesses of the mylar and of the glue were |
| 97 |
|
not considered in that document. Also the height of S3 has been modified as |
| 98 |
|
suggested from the Naples PAMELA collaborators. |
| 99 |
|
|
| 100 |
|
ND GEOMETRY COMPLETED. |
| 101 |
|
The He3 and the polyethylene (CH2) have been added to fill |
| 102 |
|
the volumes NDTI and NDPB in the neutron detector. Leonov gave us the |
| 103 |
|
details of these materials. |
| 104 |
|
|
| 105 |
|
TOP PLATE GEOMETRY ADDED. |
| 106 |
|
The top plate geometry has been simulated as a rectangular window filled |
| 107 |
|
with a mixture of titanium (90%), aluminum (6%) and vanadium (4%). It has been |
| 108 |
|
put in a N2 box having the same planar dimensions of CATA. In this box there |
| 109 |
|
are also S2 and CATA at the right positions. Then the top plate geometry has |
| 110 |
|
been completed with other eight small volumes of titanium positioned at the |
| 111 |
|
corners of the N2 box. Four of them are at the same height of CATA, the |
| 112 |
|
other four are at the same height of S2. The simulated geometry of the top |
| 113 |
|
plate is based on a simplified version of the CAD drawings. |
