09.56 DAQ continues data file S100_alpha/R18_387
FRS switching settings
DSSSD bias & leakage current OK - attachments 1
FEE64 temperatures OK - attachment 2
aida02 ASIC temp - known fault
All system wide checks OK *except* as shown - attachments 3-5
WR timestamps OK - attachment 6
ADC, PAUSE, RESUME & Correlation Scaler data time stats - attachments 7-10
per FEE64 Rate spectra - attachments 11
per p+n FEE64 1.8.L spectra - attachments 12-13
aida09 pulser peak width 57 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 14
per FEE64 1.8.H spectra - attachments 15-16
per FEE64 1.8.W spectra - 20us FSR - attachments 17-18
only aida08 & aida09 currently updating - ASIC check load and/or DAQ STOP/GO required?
Merger, TapeServer etc - attachments 19-21
BNC PB-5 settings - attachment 22
10.07 data file S100_alpha/R20
new run for new FRS setting
10.08 all histograms, stats, merger stats and data link stats zero'd
10.10 ADC data item stats (beam OFF) - attachment 23
11/16 < 20k, max 129k (aida08)
10.31 analysis of data file R18_349 (closed 06.00 this morning)
max deadtime 12% (aida04)
no timewarps
HEC data item rate 1.7kHz
11.00 tuning 168dy FRS setting
ucesb - attachment 24
spill length 3.5s, extraction time 1.5s
11.30 degraders now set to implant in AIDA DSSSDs
high rates expected
per FEE64 Rate spectra - attachment 25
ADC data item stats - attachment 26
Merger etc - attachment 27
in spill rates to MBS up 30+Mb/s, 2.5M data item/s merged
DSSSD bias & leakage current - attachment 28
c. few hundred nA step in leakage current
analysis of data file R20_33 - attachment 29
max deadtime 18% (aida08)
no timewarps
HEC data item rate 4.1kHz (c. 2.4x previous FRS setting)
Correcting for spill cycle => 5.9kHz in spill (online analysis shows no HEC events observed outside spill)
assume typical HEC event multiplicity = 3 => implant rate ~ 2.0kHz in spill or 6800 implants per spill
SC42 L/R currently report c. 4.5kHz
Note that we currently see a higher fraction of events in DSSSD#2 cf. previous setting so multiplicity assumption may be low
If we assume multipicity = 6 => implant rate ~ 1.0kHz in spill or 3200 implants per spill
we are probably somewhere in between
12.50 DSSSD bias & leakage current - Grafana - attachment 30
leakage current ramping, spill micro structure observable
FEE64 temperatures OK - attachment 31
ADC data item stats - attachment 32
per FEE64 Rate spectra - attachment 33
Merger etc - attachment 34
14.56 analysis of data file R20_106 - attachment 35
max deadtime c. 18% (aida04 & aida08), c. 12% (aida03), c. 11% (aida06), c. 9% (aida02 & aida13), c. 6% (aida05), all others <2%
no timewarps
HEC data item rate 4.2kHz
15.40 DSSSD bias & leakage current - Grafana - attachments 36-37
leakage current ramping, spill micro structure observable
FEE64 temperatures OK - attachment 38
ADC data item stats - attachment 39
per FEE64 Rate spectra - attachment 40
Merger etc - attachment 41
ucesb - attachment 42
15.57 all histograms zero'd
