| Status | End of Run 73 warmup. 1K Pot pumped out and isolated. Fridge and 4He and LN2 Trap 1 isolated, not pumped out. N2 gas in IVC. Cryostat vacuum jacket pumped out. MB lowered into pit. |
| 1000 | MC(Cernox) = 296.7 K |

| 1250 | Disconnect cables from MB, then put pit covers back on. To do this as a one-person job, I lifted the cover up on its long edge, carefully sliding it in next to the pit, between the pit edge and the fridge stand columns. After aligning it with the edges of the pit, I pivoted it on its edge lowering it down onto the pit opening - with one hand using the handle so as not to drop it hard. Lowered it down all the way so that it was still partway up on the concrete floor, with the other side resting on the pit opening lip. Did the same with the other pit cover. Then just push them in from the edge to put them completely over the pit. |
| 1305 | Assemble clean tent around IVC, connect filter hose and turn on HEPA filter. |
| 1320 | Clean inside of clean tent with methanol |
| 1335 | Check pressure in IVC: 0.33 bar on mechanical gauge. Let more N2 into IVC slowly, through the Swagelock valve on the pump manifold. |
| 1335 | Plug DCRC1 into mini-bob, then plug in ethernet to turn it on. This if for some DAQ tests - first, because IT is disabling our cdmssoft shared account and changing to spa-u-cdmssoft, so we want to make sure the DAQ works properly with the changes. And second, I want to test some modifications to the pulse viewer. |
