| 1435 | Filled LN2 cold trap. |
|---|
| 1505 | Power off two DCRC's. |
|---|---|
| Begin LHe transfer (10.4%) | |
| 1545 | End LHe transfer (96.1%) |
| 1858 | Power up two DCRC's. We didn't see the low energy events in the previous 12 hour -10V Ba-133 data set. Maybe the the detector was not biased long enough. Will try to take a longer data set. |
| Temperature fluctuates after helium transfer. |
| 1922 | Still resistance 4.46kOhm. P1=0.065mbar, G1=45mbar, G2=44mbar. |
|---|---|
| 1935 | 07111210_1935: -10V Ba-133 data long run. We'll run this until we can get the low energy events if tower temperature and DAQ permit. |
| 1937 | Timing link was not set in 07111210_1935. Restart the run 07111210_1937 |
