| status: initial LHe transfer yesterday | |
| 0820 | MC(Cernox) = 4.8 K, Sorb/1K Pot = 8.8/6.8 K, Turbo on IVC = 1.0 nbar, G1(fridge) = 553 mbar. Main bath = 55.7% |
| we only have a half-full 100L Dewar to last the weekend. The bath will fall to 15% on Saturday at 11:00. If we fill to 92% on Saturday at 11, we should be good until late Monday. the question is do we have enough LHe now for a complete fill tomorrow? Should check again what's in the hall and consider a partial fill with one of the low Dewars. |

| 0935 | Fill LN2 cold trap full. |
| 1417 | Begin LHe transfer @ MB = 48.0% (using the last dregs of a near empty Dewar, 17.8L) |
| 1438 | End LHe transfer @ MB = 47.1%. Oh well. |
| 1636 | Fill Ln2 cold trap full. |
