11:00 Visual inspection FEE64 adaptor PCBs & cabling
aida02 ground from/to other FEE64s disconnected - re-connected
aida01, aida09, aida12 - ground cabling screws to Lemo 00.250 housings loose - tightemed
12:50 Cooling water pressure & temperature OK - attachments 1 2
12:59 relay #1 power ON
13:01 relay #2 power ON
13:07 aida06 starts - panic during startup, automatic restart following 3 minute timeout
DAQ reset, setup
Check ASIC Control - browser tab timeout
AIDA MIDAS HTTPD server console log - attachment 3
Appears to have restored ASIC settings 2024Dec13-17.02.45 saved yesterday
aida10 ASICs #1 & #2 positive input, ASICs #3 & #4 negative input
slow comparator 0xa (all p+n junction FEE64s and aida10), 0xf (n+n Ohmic FEE64s)
13:28 tar ASIC settings - attachment 4
[npg@aidas-gsi]$ cd /MIDAS/FEE_ASIC
[npg@aidas-gsi FEE_ASIC]$ tar cvf /tmp/FEE_ASIC.tar .
System wide checks
Sync ASIC clocks - attachment 5
Clock, ADC calibration, WR decoder, FPGA timestamp, PLL checks - attachments 6-11
all OK *except* aida02 WR decoder error
WR timestamps OK - attachment 12
FEE64 temps OK - attachment 13
13:45 Detector bias ON - attachment 14
BNC PB-5 pulser settings - attachment 15
Pulser connected to all p+n junction FEE64s *except* aida10
ADC, DISC, PAUSE and MBS correlation scaler stats - attachments 16-19
aida02 rate significantly lower than yesterday - https://elog.gsi.de/despec/Implantation+Stack/8
high rates observed for aida08, aida11 and aida14 - which are not connected to a DSSSD!
per FEE64 Rate spectra - attachment 20
per p+n junction FEE64 1.8.L spectra - attachment 21
aida09 pulser peak width 56 ch FWHM = 39 keV FWHM
consistent electronic noise for all p+n junction FEE64s (cabling+DSSSD)
electronic noise of p+n junction FEE64s (cabling *only*) higher and more variable cf. https://elog.gsi.de/despec/Implantation+Stack/8 attachment 5
per p+n junction FEE64 1.8.W spectra 20us FSR - attachments 22-23
per n+n Ohmic FEE64 1.8.W spectra 20us FSR - attachment 24
WR timestamps OK - attachment 25
14:43 DAQ STOP
Data transfer enabled
Select Tape Server -> Next Run
DAQ GO data file R3
Merger, Tape Server - attachments 26-27
data transfer rate c. 900k data items/s cf c. 300k data items/s yesterday https://elog.gsi.de/despec/Implantation+Stack/8
16:45 DAQ STOP
Data transfer disabled
Detector bias OFF
