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

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.
