0903	DAQ is still running but the event rate is < 1Hz. It's not collecting data. Stop the DAQ. A few series before the current one also have the same problem. The connections to DCRCs are still OK. The readout vi can still readout data without problem. Don't know what happened.

Data collected in the last run

13G     ./07110719_2024
11G     ./07110719_2255
3.4G    ./07110720_0122
1.9G    ./07110720_0342
1.3G    ./07110720_0602
400M    ./07110720_0822

The first two series look OK. The series that follow went bad. They are not worth the time to process and analyze. I'll just delete them.

0911	Test run 07110720_0911_F0001 to check the DAQ. The timing link seem to be lost. Tried to reset it, it didn't work.
2220	Start to take data 07110720_2220. -2.5V on DIB1 DCRC33, 2.5V on DIB2 DCRC30. Trace length 3.2768ms, lookback time 400us. trigger on phonon channels. Ba-133 source.
