      BNC PB-4 Pulser frequency switched from 250Hz to 25Hz range

09:54 ASIC Temperatures - Attachment 1
      Bias and leakage currents ok - Attachments 2 & 3
      Statistics - Attachment 4

10:19 Output of analysis of R1_291 - Attachment 5

11:02 Pulser widths measured before changing jumpers (In log book)
      DAQ stopped on Run R1_304

11:31 All field plane jumpers removed (Jumpers 1&3)
      System wide checks ok
      ASIC load check ok

11:37 DAQ started online only
      Statistics - Attachment 6
      FEE temperatures - Attachment 7

11:46 Layout 1 - Attachments 8 & 9
      Layout 2 - attachments 10

13:38 Layouts 3 - Attachment 11
      Layout 4 - Attachment 12
      Pulser widths measured using 1.8.L spectra.
      Most channels show an increase in noise with the FWHM increased by ~5-10 channels
      (Recorded in log book)

13:55 Layout 7 p-side waveforms - Attachments 13 & 14
      Layout 8 n-side waveforms - Attachments 15 & 16
      For comparison with jumpers on see yesterday's elog entry: https://elog.ph.ed.ac.uk/AIDA/674

14:02 DAQ stopped

14:23 PCB ground plane jumper removed from all adapter boards (Jumper 2)

      Bias and leakage currents ok T = 23.0 DP = +8.8 H = 38.7% - Attachment 17
      System wide checks all ok
      ASIC load check ok

      DAQ Started

14:44 FEE temperatures all ok - Attachment 18
      Statistics - Attachment 19

14:54 Layout 1 - Attachment 20 & 21
      Layout 2 - Attachment 22

15:17 Layout 3 p-side pulser - Attachment 23
      Layout 4 n-side pulser - Attachment 24

      Pulser widths measured using 1.8.L spectra

      In comparison with just having the FP jumpers removed for channels that were not noisy before they show no
      to only minor increases in noise.

      However channels that were previously noisy with all jumpers on show drastic increases in the amount of
      noise. Increases in the FWHM of up to 80ch

13:55 Layout 7 p-side waveforms - Attachments 25 & 26
      Layout 8 n-side waveforms - Attachments 27 & 28

      DAQ Stopped

16:15 Detector bias turned off as replacing the jumpers is challenging

16:55 All jumpers back on. I advise starting with all on the new boards tomorrow and removing if needed.
      Pain to put back on when mounted with cables.

16:59 System wide checks ok
      Bias back on and leakage currents ok - Attachment 29

17:09 Statistics - Attachment 30
      FEE temperatures - Attachment 31

      By putting the jumpers back the statistics appear to have recovered to a similar level to this morning

17:25 FEEs powered down to do a power cycle for Patrick

17:50 FEEs powered up

18:00 Same javascript errors as yesterday when setting up DAQ
      System wide checks all ok
      FEE Temperatures ok
      
18:06 DAQ started
      Statistics similar to before power cycle - Attachment 32
      Layout 1 looks good - Attachments 33 & 34

18:14 DAQ stopped

18:16 DAQ Started
