Detailed Infos About TAS Ladders

The Tracker Ladders realized with not-refractive windows for the alignment system are 40. After the Tracker modifications for the AMS-02 PM Configuration, 5 of this ladders are no longer used in the TAS. Here there is the list of the 35 TAS ladders used.

The TAS ladders are acquired without any compression. In order to get a manageable event size only a small set of strips around the laser crossing position on the illuminated ladder are read. Here there is the list of the active regions:

Ladder type p-side windows n-side windows
0 None None
1 64-255 640-703, 960-1023
2 64-255 704-831
