10:34 Detector Bias a leakage currents all ok. (Attachments 1 and 2)
Temperatures all ok (Attachment 3)
All system wide checks ok other than clock status see attachment 4
DAQ continues to run ok (R124) (No stop at 6:30am)
DAQ running at about 14MB/s to disc which is faster than before.
Most likely due to the increased rate in detector 1 which is represented at FEEs 17, 20, 22 and 23 in
attachment 5.
Also attached are the spectra for layouts 1-4 & 7-8 as attachments 6-11
When looking at the pulser spectrum in layouts 3 and 4 (attachments 9 and 10) we see that the pulser peaks
relating to this detector is broader shown by
the decreased peak height.
Comparing the waveforms in attachments 11 and 12 to those taken on Monday 31st Oct we see that the noise
in nnaida 5 and 6 has been greatly reduced.
On the others however there appears to be an increase in the amplitude of the noise.
11:25 The second putty window for leakage currents was found to have been frozen for the past 24 hours.
Was reloaded and updated leakage currents are in attachment 13 and 14
12.15 Analysis of R124_291 shows ADC & disc data synchronised - see attachment 15
Analysis of data file - see attachment 16
18:26 DAQ stopped, presumably during LN2 fill cycle.
Restarted the merger and tried "Stop" on the DAQ control page. ~50% of nnaida now show "error."
R124 closed 18.29
Could not regain control of the system. Jorge switched BRIKEN to its internal clock and FEEs power cycled @
19.20.
23.35 DAQ started (R126 - no storage mode)
DSSSD bias & leakage currents OK - see attachment |
