Subject*:

10:13 all system wide checks OK *except* nnaida7 fails ADC calibration

FEE64 temperatures OK - see attachment 1
      good event statistics OK - see attachments 2

detector biases & leakage currents OK - see attachment 3

Temperature + deg 24.7C dew point +8.6 deg C RH 35.0%

Merger and TapeServer ok

10:30 DAQ, merger, TapeServer stop

Alpha run stopped at AIDA file TapeData/May19/R2_5

slow comparator threshold lowered to 10 keV (0xa)

DAQ start, not writing to file

good event statistics after lowering threshold, ok (attachment 4)

10:49 1.8.W spectra 20ms FSR - attachments 5 & 6

11:25 started writing to file R3 (sync test)
      low threshold run at 5mb/s

11:33 DAQ stop (R3)

slow comparator threshold raised to 100 kev (0x64)

DAQ start, alpha run

Writing to file TapeData/May19/R4

18.49 alpha background

ASIC settings 2018Oct03-13.26.58
      *except* slow comparator 0xa -> 0x64

BNC PB-4 Pulser OFF

FEE64 temperatures OK - see attachment 7
      good event statistics - see attachments 8 - nnaida1 405k & nnaida17 368k, all other FEE64s c. 380Hz as
expected
      ASIC check for *all* ASICs & FEE64s restored all FEE64 rates to expected c. 380Hz - see attachment 13

detector biases & leakage currents OK - see attachments 9 & 10

Merger OK - no error messages - see attachment 11
      TapeServer OK - see attachment 12

all system wide checks OK *except* nnaida7 fails ADC calibration *and* Check Sync errors not counted Since
Baseline - see attachment 14

DAQ stopped May19/R4_3
