10:18 Leakage and bias ok - Attachment 1
FEE temperatures ok - Attachment 2
Statistics - Attachment 3
DAQ continues ok
10:23 DAQ stopped on R7_10
Alpha run through night
10:28 MIDAS Sort spectra from the alpha run
Ep versus En - Attachment 4
x versus y 2D hit pattern - Attachment 5
Front versus back multiplicity - Attachment 6
2D Hit pattern indicates detection of alphas in all 4 regions of each of the 6 detectors
indicates cabling is ok
11:55 FEEs turned off after being unable to recover after crash
13:49 FEEs powered on again
Pi monitor indicates panic on nnaida22 the FEE that crashed
ReSync done on setup except for 23 and 24
Master ReSync done succesfully
ASIC settings loaded default to 2017Mar27
Restoring 2017Oct22
System wide checks ok
Leakage and bias ok - Attachment 7
FEE temperatures crashed - Attachment 8
Upon reboot all rates across the FEEs appear lower
In particular 13 and 14. Thresholds have been reduced back to 0xa for all ASICs on both FEEs
Layout 1 linear common y of 2000 - Attachment 9
Layout 1 log common y of 10 - Attachment 10
All front side FEE64 1.8.W waveforms - 20us range - Attachment 11
All back side FEE64 1.8.W waveforms - 20us range - Attachment 12
All front side FEE64 1.8.W waveforms - 2ms range - Attachment 13
All back side FEE64 1.8.W waveforms - 2m range - Attachment 14
FEE64 nnaida13 1.*.W waveforms - Ibias LF 0xf - 2ms range - Attachment 15
Statistics after switch and thresholds lowered - Attachment 16
Pulser widths measured. On boards changed 10 out of 12 FEEs show greater than 10% improvements
11 out of 24 total show greater than 10%
FEE stats post pulser width - Attachment 17
New ASIC settings DB key: 2017Oct23-14.38.03
Slow comparator 0xa for all FEE64s and all ASICs
IBias LF feedback at 0xf for all front side FEEs except nnaida 2 which is at 0xc
IBias LF feedback at 0xb for all back side FEEs
ASIC settings DB file checked OK
Ambient temperature +23.3 deg C, D.P +7.1 deg C, R.H. 35.2%
Julabo FL11006 set point +20.0 deg C, water le
