In this page the relation between Layer 3 strips (strip-X, strip-V) and electronics channels (FEB_label and GEMROC-TIGER) is shown. This is the mapping matching the convention used in CGEMBOSS.

Mapping overview[edit | edit source]

Layer 3 has 1664 strip-X (0-1663) and 2790 strip-V (0-2789). It is divided into two sheets so strips are divided into two equal parts:

Sheet 0: strip-X (0-831), strip-V (0-1394)
Sheet 1: strip-X (832-1663), strip-V (1395-2789)

All Layer 3 FEBs channels follow the same order, according to the pinout shown here: L3 FEB pinout

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

chip 1 reads 14 strip-X and 48 strip-V
chip 2 reads 32 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=52, chip 1 --> ch. 61, 40, 52, 50 (V-strip, last FEB of 1st anode foil, IN side)
FEB_label=61, chip 1 --> ch. 61, 40, 52, 50 (V-strip, last FEB of 2nd anode foil, IN side)
FEB_label=70, chip 1 --> ch. 61, 40, 52, 50, 45 (V-strip, last FEB of 2nd anode foil, OUT side)
FEB_label=79, chip 1 --> ch. 61, 40, 52, 50, 45 (V-strip, last FEB of 2nd anode foil, OUT side)

Strip-X[edit | edit source]

Sheet 0: strip-X (0-831)
Sheet 1: strip-X (832-1663)

Sheet 0[edit | edit source]

Strips FEB label GEMROC TIGER Strips_sheet

Sheet 1[edit | edit source]

Strips FEB label GEMROC TIGER Strips_sheet

Strip-V[edit | edit source]

Sheet 0: strip-V (0-1394)
Sheet 1: strip-V (1395-2789)

Sheet 0[edit | edit source]

Strips FEB label GEMROC TIGER Strips_sheet

The connector with one less strip is marked in bold

Sheet 1[edit | edit source]

Strips FEB label GEMROC TIGER Strips_sheet

The connector with one less strip is marked in bold
