| 0850 | Status: pumping on IVC with turbo pump. MB in pit. Cf source in lead&poly castle activating detector since 2015/11/25. |
| 0855 | Put Cf source back in safe. |
| 0900 | IVC pressure pumping / with pump valved out = 5.4 / 340 e-6 mbar |
| 1035 | Place LN2 cold trap 1 back in bath and fill. |
| 1045 | Vacuum inside dewar and raise dewar. |
| 1055 | G1/G2/P1 = 121.8/560.5/2.6 mbar with all valves closed and pump off. Open V9 and turn on 3He pump, G2 rises to 777.8 mbar. |
| 1100 | Open V5 and V3 to pump P1 and G1 volumes to dump. |
| 1135 | G1: 0.6mbar, G2: 787.3mbar, P1: 15ubar. |
| 1145 | Commence cryocleaning mixture through Cold Trap 1. V1 open to 12.9% |
| 1200 | Adjust V1 to 13.1% |
| 1300 | Finish attaching Main Bath, all screws tightened |
| 1310 | Turn on He4 Rotary Pump and pump out Dewar. |
| 1350 | Open leak checker to IVC, get background leak rate of ~3-4 pbarL/s. Commence filling the main bath full of He. Leak rate increases slowly over next few minutes until main bath is full and leak rate is at ~10-13 pbarL/s. No sign of leak. |
| 1356 | Pump out 1K Pot. |
| 1400 | Add 4.6 mbar of He exchange gas to IVC. |
| 1405 | Commence LN2 transfer. |
| 1425 | Cernox MC thermometer = 295 K (down about 2 K) |
| 1440 | MC = 284 K, IVC = 4.0 mbar |
| 1500 | MC = 259 K, IVC = 3.4 mbar |
| 1555 | LN2 storage Dewar runs empty. Level resistor reads only 1.030 Ω when lowered into bath (0.985 Ω at room temperature). Need to refill storage Dewar. |
| 1600 | MC = 174 K, IVC = 2.2 mbar |
| 1605 | Cease cryocleaning mixture. Pump mix from Trap 1 to dump through valves 12a, 3, 6(100%), 9. |
| 1615 | Trap 1 down to G1/P1 = 0.6/0.085 mbar. Close V3 to isolate trap (monitoring its pressure on G1) and remove trap from LN2 to warm up. |
| 1625 | G2 (dump) reads 795.4 mbar. Close V6 and V9 and turn off 3He pump |
| 1645 | MC = 152 K, IVC = 2.2 mbar. Sorb hasn't changed, still reading 150 K |
| 1650 | G1 (Trap 1) has risen to 38.7 mbar, no longer frosty but still warming |
