| | Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50 |
| | Taking Cf data overnight with MIDAS. Last flash at 0648. Charge biases now at zero - flash-and-take now does this at the end of the sequence. |
| 0745 | Small temperature spike to 33.5mK. Returned to base temperature after several minutes. |
| 0900 | Main bath = 6.0%. G1/G2: 109.6/107.5. P1: 100ubar, P2: 5.5mbar, 1KPot temperature: 1.595K, Tower temperature: 32.1mK. Close needle valve of 1K pot. Pump mixture to dump. P1 rises to 0.28mbar, then begins falling. |
| | Fill LN2 cold trap full. |
| 0905 | 1K Pot temperature drops to 1.404K, P2: 0.85mbar. Close 1K Pot speedivalve. Temperature rises to 1.6K. |
| 0910 | Tower temperature: 241mK. Turn on mixing chamber heater to 20mW. Turn the yellow valve on the He4 Pump exhaust from Recovery to Exhaust. |
| 0915 | P1 rises to 9.0mbar before dropping quickly back below 1mbar. Open V12A and Cold Trap 1 speedivalve to pump to dump whatever remaining mixture may still be in there. |
| 0917 | G2 shows 335mbar of mixture collected so far. Tower temperature at 1.38K, Mixing Chamber temperature at 1.489K. |
| 0927 | Turn off He4 Pump. |
| 0937 | Tower temperature at 1.29K. G2 shows 459mbar of mixture collected in dump. |
| 1130 | Tower temperature at 11.7K. G2 shows 799mbar of mixture collected in dump. |
| 1255 | Mixing Chamber temperature at 9.8K. Sorb temperature at 5.4K. Isolate Turbopump to measure pressure in line leading up to IVC: 8.6E-6mbar. Open IVC. Pressure at 1.2E-5mbar. Open turbopump to IVC and pressure begins dropping. |
| 1300 | G2 shows 798mbar of mixture collected in dump. G1 is below 1mbar. P1: 16ubar. Close V1 and V6 with Mixing Chamber heater still on. |
| 1305 | P1 doesn't rise from 16ubar. All mixture must be recovered from fridge. Open V1 and V6. Close Condensor Line Speedivalve and Gate Valve. Then close V1 and V6 again. |
| | Main Bath = -0.1%. Close He Recovery valves, but leave Main Bath isolated from atmosphere. |
| | Close V12A, V12B, and both Cold Trap Speedivalves. Remove cold traps from LN2 bath and open V11A, V11B, V7, V2A, and V5A to connect Cold Traps to P2. |
| 1310 | V6 closed all the way. Close V9 to isolate dump. Close manual valves on dump to further isolate mixture over break. |
| | Turn off He3 pump. |
| 1400 | Traps are warm, and P2 reads 26mbar. Turn on He4 pump and commence pumping out traps. |
| 1405 | MC temperature = 7.5K. |
