11.00 Detector biases and leakage currents - see attachments 1-2 FEE64 temperatures - see attachment 3 DAQ ran overnight without problem - statistics - attachments 4-8 Plan for today 1) Develop AIDA external trigger output for fast LEC/MEC discriminator threshold 0x4, or lower 2) Replace non-rev B MACB with rev B MACB in master timestamp chain (NIM module #2) 16.15 Non-rev B MACB in master timestamp chain replaced with rev B MACB module FEE64s power cycled and rebooted. System ReSYNC'd successfully System-wide tests clock states 24/24 pass adc calibration 24/24 pass ASIC clock timestamp check 23/24 pass, nnaida19 fails SYNC errors not counting 23/24 pass, nnaida19 fails N.B. We obtained the same nnaida19 errors before rpelacing non-rev B MACB and with FEE64 previously installed as nnaida19 Module timestamps - see attachment 9 Master timestamp module nnaida6 - all clocks locked Fitted ground jumpers to front and rear field plate connections on all four adaptor PCBs for each of DSSSD#2 - #5, i.e. DSSSD#1 - #6 now have field plate ground jumpers fitted. See attachments 10 & 11 showing discriminator rates before and after fitting these additional ground jumpers (LEC/MEC fast discriminator threshold 0x4 or 0x5) 18.25 NP1306 R58 207Bi + 60Co LEC/MEC disc threshold test ASIC settings 2016Jun03-21.03.42 21.05 End R58 21.30 Moved extant data acquisition server options files to /MIDAS/DB/EXPERIMENT/AIDA/nnaida?/CONTENTS.BAK-030616 Saved options for all data acquisition servers with TS_SYNC_PHASE = 0x3 MACB_TRIG_MODE = 0x4 ASIC Settings DB key 2016Jun03-21.03.42 (all LEC/MEC fast disc settings 0x5 except nnaida5 & nnaida6 = 0x20) Encoding: HTML ELCode plain Suppress Email notification
