01:02 Briken and BigRIPS daq stops

01:03 Briken Starts run 8
      BigRIPS starts run 3008

01:40 Phong noticed a significant difference in the noise in the (raw) low energy spectra a few of the FEEs when
      comparing the runs right before and right after the power-cycle  (See Attachment 12) required to recover 
      the DAQ crash last afternoon (June 5th). 
      NNAIDA 22, 21, 14, and 13 had a much higher count rate after the power cycle, and what seems like a lower
      threshold. We can't observe the pulser peak in any of those.
      NNAIDA 13 has the highest count rate, and the waveforms show what looks like noise with a regular
      frequency (attachments 4 - 7)

      For reference, we include the waveform of other positive FEEs 8-11

06:16 Analysis of R5_270 - attachment 22
      Three MBS errors

06:34 130Cd decay curve - attachments 22 and 23
      Despite the large amounts of noise in the detectors it is still possible to observe decay curves. They are
cleaned up a lot
      by applying a multiplicity cut (attachment 22 with attachment 23 without. Further cuts and vetos could be
applied to clean up further.
      The fit in attachment 22 gives a half life of 182ms which is not quite the expected 162ms but a reasonable
first fit.

07.14 Layout - 1.8.W waveforms - see attachments 24-27
      No significant change in intrinsic/extrinsic noise cf. previous screenshots
