| Status | Run 74 in progress. Warming up a second time to fix the DIB2qI short which reappeared at around 130 K. N2 in Cryostat Vacuum Jacket, some He in IVC. Mixture in fridge and dump. |
| 1130 | MC(Cernox) = 207.1 K and rising at 3.8 K/hour. |
| | this implies a warming time constant of 23 hours assuming room temperature = 295 K. Suppose dew point is 275 K, then we'll reach this in 34.25 hours, which is 9:45 pm tomorrow night. |
| 1500 | MC(Cernox) = 219.2 K and rising at 3.2 K/hour. (Updated time to reach dew point: 10:30 pm tomorrow night) |
| 1515 | Matt enters lab |
| 1515 | Release some pressure from MB |
| 1520 | Start pumping mixture out of fridge to dump |
| 1525 | Check for DIB2qI shorts from feedback, drain, source: non seen, all less than 0.3 nS. |
| 1545 | Take side coax ST-3-8 to wirebond lab to fix open qO bias resistor.  |
| | Hard to tell which wirebond was bad even through the microscope. Had to tap them with a pointed stick - found one connection was loose, the one connecting the first to the second resistor, counting from the detector side. Remove bond with tweezers.  |
| 1600 | Replace wirebond on second attempt. Wirebond settings: power 475/475, defaults for everything else.  |
| 1605 | Replace copper foil cover on side coax. Electrical checkout on ST-3-8 charge channels: all resistors good, no shorts to chassis |
| 1610 | Stop pumping mixture to dump. Dump(G2) = 757.4 mbar. Close all IGH valves and turn off 3He pump. |
| 1615 | Matt exits lab |
