09.56 DAQ continues data file S100_alpha/R18_122
FRS setting 162Eu
DSSSD bias & leakage current OK - attachments 1-2
FEE64 temperatures OK - attachment 3
aida02 ASIC temp - known fault
All system wide checks OK *except* as shown - attachments 4-6
WR timestamps OK - attachment 7
ASIC settings aida01 & aida02 - attachments 8-9
ADC, DISC, PAUSE, RESUME, WR & Correlation Scaler data time stats - attachments 10-15
per FEE64 Rate spectra - attachments 16-18
unusually can observe HEC Rates esp. in DSSSD #1
per p+n FEE64 1.8.L spectra - attachments 19-21
aida09 pulser peak width 61 ch FWHM
common x/y scale => peak height proxy for width => all p+n FEE64s similar pulser peak widths
per n+n FEE64 1.8.L spectra - attachment 22
per FEE64 1.8.H spectra - attachments 23-24
per FEE64 1.8.W spectra - 20us FSR - attachments 25-26
only aida08 & aida09 currently updating - ASIC check load and/or DAQ STOP/GO required?
Merger, TapeServer etc - attachments 27-28
ucesb - attachments 29-30
spill cycle reported as 3.5s, extraction 1.5s
10.36 All histograms & stats zero'd
BNC PB-5 settings - attachment 31
DSSSD bias & leakage current - Grafana Alerting - attachment 32
can observe bias & leakage current in greater detail
DSSSD #1 bias stable, c. 10s nA micro structure observed in leakage current
DSSSD #2 bias c. 10mV variations, micro structure observed in leakage current but smaller variations cf. DSSSD#1
10.46 analysis of data file R18_131
max dead time 12% aida04, 6% aida02, all others 0.1% or less
no timewarps
HEC data item rates 1.6kHz - correcting for spill cycle => 2.3kHz in spill (online analysis shows no HEC events observed outside spill)
assume typical HEC event multiplicity = 3 => implant rate ~ 760Hz in spill or 2700 implants per spill
SC42 L/R currently report c. 2kHz
