  1. Belle II numbering y y x x z z

  2. Electronics mapping (rawdata) col 2 col 1 col 0 col3 • row: carrier level, 0-3. • column: daughter card slot, 0-3. • channel: channel on ASIC, 0-7. row 3 row 2 row 1 6420 row 0 7 5 31 6420 7531 channel (For all modules.) y z x SCROD bottom. Coordinate of Belle II This mapping is checked by using test pulse on front-back board.

  3. Electronics mapping (Belle II) • pmt = row/2 x 16 – col + mod x 4 + 4. • ch = 1 (if channel = 7), 2 (if channel = 5), … • (mod = module ID 0-3) 17 18 19 20 1314 15 16 910 11 12 1 2 3 4 5 6 7 8 pmt 1234 ch (Example for module 0.) y z x SCROD bottom. Coordinate of Belle II

  4. Electronics mapping (beam test ’11) • pmt = row/2 x 12 – col + mod x 4 + 4. • ch = 1 (if channel = 7), 2 (if channel = 5), … • (mod = module ID 0-3) 13 14 15 16 1314 15 16 910 11 12 1 2 3 4 5 6 7 8 pmt 1234 ch (Example for module 0.) y z x SCROD bottom. Coordinate of Belle II
