Layer 2 (CGEMBOSS 2024)

In this page the relation between Layer 2 strips (strip-X, strip-V) and electronics channels (FEB_label and GEMROC-TIGER) is shown. This is the new mapping matching the convention used in CGEMBOSS (April 2020) and also fixing FEB_label order (Nov 2023), i.e. first strip-X on first FEB (FEB_label=16).

Re-mapping (Nov 2023)

Mapping overview

Layer 2 has 1260 strip-X (0-1259) and 2154 strip-V (0-2153). It is divided into two sheets so strips are divided into two equal parts:

Sheet 0: strip-X (0-629), strip-V (0-1076)
Sheet 1: strip-X (630-1259), strip-V (1077-2153)

All Layer 2 FEBs channels follow the same order, according to the pinout shown here: L2 FEB pinout

Only channels 0-60 of each chip are connected to a strip (ch. 61-62-63 are disconnected):

chip 1 reads 14 strip-X and 47 strip-V
chip 2 reads 31 strip-X and 30 strip-V

The following channels are not connected to any strip because the correspondent FEB is connected to the last connector of the anode foil:

FEB_label=36, chip 1 --> ch. 57 (V-strip, last FEB of 1st anode foil) - OLD MAPPING
FEB_label=43, chip 1 --> ch. 57 (V-strip, last FEB of 2nd anode foil) - OLD MAPPING

After Nov. 2023 re-mapping:

FEB_label=36 becomes FEB_label=30, chip 1 --> ch. 57 (V-strip, last FEB of 1st anode foil)
FEB_label=43 becomes FEB_label=37, chip 1 --> ch. 57 (V-strip, last FEB of 2nd anode foil)
