| 0910 | Fill LN2 cold trap full. |
| 0934 | take out 133Ba source and put near fridge |
| 0957 | overall rate down to 51 Hz about 24 hours after PuBe activation using 12 50ms samples of DCRC1 PhA |
| 1006 | Start sequence of 3 one-hour data series of 0V data 133Ba source in, with Frontend Gain = 5/2/5, OG = 8/3/8, with 1000 beginning randoms, with no flashing in between series, trigger on DCRC3 PhD which is PFS1 at 70 sample threshold |
| 1205 | Returned empty He dewar from a few transfers ago, with 2.5L of LHe remaining. Two dewars for long weekend have not yet arrived, but Bill has filled a few dewars in hallway ~60 L full. |

| 1623 | Fill LN2 cold trap full. |
| 1627 | Put Ba source in safe. |
| 1629 | Start sequence of 43 one-hour data series of 0V data with Frontend Gain = 5/2/5, OG = 8/3/8, with 1000 beginning randoms, with no flashing in between series, trigger on DCRC3 PhD which is PFS1 at 70 sample threshold |
