00.28 all histograms & stats zero'd
      baseline counters

ASIC settings 2021Apr29-13-16-00
 *except* slow comparator 0x64 -> 0xa

BNC PB-5 pulser
 to p+n FEE64s only
  amplitude 1.0V
  attenuator x1
  decay time 1ms
  polarity +
  frequency 2Hz

all AD9252 waveform ADCs disabled

Tape Server -> no storage mode

00.36 check ASIC control all FEE64s all ASICs

all system wide checks OK

00.41 BNC PB-5 pulser rate increased from 2Hz to 22Hz per request by HA/NH - to ensure DTAS correlation checker has sufficient rate of identified pulser events

per p+n FEE64 1.8.L spectra - attachment 1
 aida01 pulser peak width 88 ch FWHM

per FEE64 rate spectra - attachment 2

adc, pause and correlation scaler data items - push, aida01 and aida02 stats - attachments 3-8

FEE64 temps OK - attachment 9

DSSSD bias & leakage current OK - attachments 10 & 11

02.28 aida05 zero adc data items, unable to halt aida05 - all other FEE64s OK

restart NewMerger -> now able to halt aida05

DAQ go OK, merge rate c. 1.4M data items/s

per FEE64 1.8.H spectra - attachments 12 & 13
 approx flat distribution to c. 10GeV

adc data items stats OK - attachments 14

FEE64 temps OK - attachment 15

DSSSD bias & leakage current OK - attachments 16 & 17

02.55 Some problems with GO4 data analysis for PID (FRS PID looks OK). 204Pt setting. Will commence writing data to disk file S505/R2_0

04.12 per FEE64 1.8.H spectra - attachments 18 & 19
      c. 9GeV peak in upstream DSSSDs (aida01, 2, 3 & 4) indicating (high energy) heavy fragments are stopping
      Low energy events near c. 200MeV lower mass, high energy, low energy loss - fission fragments?

04.20 per FEE64 stats spectra - attachment 20
      indicates implant x-y distribution - off centre (more significantly in x than in y) but DSSSDs appear to see most of distribution
      remember raw distro will have significant fraction of fission fragments - may be misleading - need to gate on high energy events to see x-y distro of ions of 
interest

adc data items stats OK - attachments 21

FEE64 temps OK - attachment 22

DSSSD bias & leakage current OK - attachments 23

06.10 per FEE64 rate spectra - attachment 24

per FEE64 1.8.H spectra - attachments 25 & 26

per FEE64 stats spectra - attachment 27
