| | Cooling down after discovering short from DIB3 QET A to chassis at 77K (again). Replaced side coax & checking for leaks. |
| 1302 | MC (Cernox) = 296.5 K, Turbo pump = 14 nbar, IVC = 0.3 ubar, G1/G2 = 2/513 mbar. P1/P2 = 0.34/30 mbar. |
| 1305 | Tighten fridge screws |
| 1320 | Put leak detector on IVC with turbo still pumping. Leak = 30 pbarL/s, turbo = 19 nbar. |
| 1322 | Try valving out turbo. Leak → 470 pbarL/s. This is a factor of 10 lower than yesterday, but still a factor of ~10 too high. |
| 1342 | He spray test showed a slight increase to ~600 pbarL/s near the top of the stripline tube, but no other leaks found. |
| 1420 | Raise main bath. |
| 1438 | Close off IVC valves. Start pumping on dewar jacket with scroll pump. |
| 1520 | Dewar jacket pressure reached 1.0e-2 mbar, start pumping on dewar jacket with turbo pump, turn off scroll pump. |
| 1526 | Turbo pump reads 1.6e-4 mbar, decreasing. |
