> 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
