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%
