Ok to Globtop FEB Validation Tests • Evaluation of FEB´s performance: • CharacterizationandQuantification of the mean pedestal (baseline) and the ASIC Noise (pedestal RMS) • Looking for deadandnoisy ASIC channels
ASIC 1 Good Results ! ClearPEM Sonic FEBs – Test Results ASIC 0
ClearPEM Sonic FEBs – Test Results P36 Bad Results ! P31 P10
FEB Validation Tests 1st Batch 2nd Batch - 22 FEBs CERN (C1, C2,…, C22) -> OK: 12/22 - 10 FEBs Photochemie (P1, P2,…, P10) -> OK: 8/10 - 40 FEBs Photochemie (P11, P12,…, P50) -> OK: 33/38
