Owl Shift Summary
------------------

Started shift with question about the NA Plane1 L-PMT TDCs 26 and the ADC for 
this channel because they seemed to have few hits.  Called RC, and he said not 
to worry about it for the night - will call the experts in the morning.  HV 
seems to be ok for this channel.  TDC/ADC 26 in online gui plots corresponds to 
the N1 scaler 27 according to Peter M.

00:10 - Production Run 3085 ended.

00:15 - Left Q1 tripped because of liquid level fluctuation.

Called for controlled access to reset.  

00:20 - ended Compton run 10517.

00:50 - Q1 ramped back up.  Asked MCC for 45 uA of beam.

Started taking data again at 00:53.
Began Compton Run 10518 at 00:55.

Production runs on tilted Carbon

Run 3086 - 00:53-01:36  200k events

Run 3087 - 01:36-02:17  200k events

Run 3088 - 02:18-03:04  200k events

Run 3089 - 03:05-03:49  200k events

During run 3089, current changed from 45 uA to 40 uA.

Run 3090 - 03:49-04:37  201k events

MCC called and will try to run 45 uA again.

Run 3091 - 04:38-05:37  171k events

Need to reboot ROC5 because deadtime was high (99%)  - rebooted TS2.

Compton Run 10518 - end of run failed.  Restarted coda, and started run 10519 
at 05:14.

Run 3092 - junk -> testing DAQ.

After doing data replay, of the following runs:

Run 3093 - 05:46-06:30  200k events

Run 3094 - 06:30-07:16  200k events

Run 3095 - 07:16-08:02  192k events

we noticed that the Big Bite histograms are empty.  We still have a problem 
with ROC5.  So this data is probably useless.  I'm sorry!

We are now working to fix the problem.
