Electronics mapping (rawdata) row: carrier level, 0-3. column: daughter card slot, 0-3. channel: channel on ASIC, 0-7. row 0 row 1 row 2 row 3 col 3col 2col 1col channel This mapping is checked by using test pulse on front-back board. (For all modules.) SCROD bottom. x y z Coordinate of Belle II
Electronics mapping (Belle II) pmt ch pmt = row/2 x 16 – col + mod x ch = 1 (if channel = 7), 2 (if channel = 5), … (mod = module ID 0-3) (Example for module 0.) SCROD bottom. x y z Coordinate of Belle II
Electronics mapping (beam test ’11) pmt ch (Example for module 0.) pmt = row/2 x 12 – col + mod x ch = 1 (if channel = 7), 2 (if channel = 5), … (mod = module ID 0-3) SCROD bottom. x y z Coordinate of Belle II
