| 1040 | Fill LN2 coldtrap full. |
| 1055 | Commence tests on mixture with Nader. Initially mixing chamber temperature at 135.0 mK, G1 at 101.6 mbar, G2 at 87.5 mbar, P1 at 0.11 mbar, and P2 at 18.0 mbar. We have limited amount of time before we must perform a LHe transfer as the LHe level=2.7% and 1K Pot temperature at 1.634 K. Still at 4.24 kΩ (1.19 K), and cold plate at 6.66 kΩ (317.2 mK). Begin a singleshot test by opening V9 and closing V13A. After 5-10 minutes G1 has dropped to 40 mbar and continues dropping fast, suggesting that a buildup is not the problem. At this time G2=99.6 mbar and is rising, and mixing chamber temperature is at 112.2 mK and dropping. |
| 1130 | The mixing chamber temperature has stopped dropping quickly and has begun to stabilize at 77.35 mK, with P1=0.035 mbar, G1=9.0 mbar, and G2=130 mbar. Close V9 and open V13A. |
| 1140 | Current mixing chamber temperature at 86 mK, Still temperature at 1.05 K, and cold plate temperature at 346 mK. The cold plate is currently much too hot. We want it to be closer to 130 mK. |
| 1145 | Still heater turned on and increase to 1.5 mW. Mixing chamber temperature drops. |
| 1154 | Still heater increase to 2.0 mW. |
| 1203 | Close V13A. |
| 1210 | Currently mixing chamber temperature at 57.2 mK with G1=20 mbar, G2=224 mbar, P1=0.065 mbar. 1KPot temperature at 1.496 K. We should do a transfer soon. |
| 1222 | Mixing chamber temperature at 44.58 mK with G1=11 mbar, G2=370 mbar, and P1=0.060 mbar. 1KPot temperature at 1.497 K. Open V9 until G2 reads 180 mbar, then close V9. Close the manual cold trap 1 valve, then open V13A. Slowly open manual cold trap valve. After it has been opened, G1=128 mbar, and G2= 119 mbar. Mixing chamber temperature begins to rise, as expected. |
| 1232 | Mixing chamber temperature peaks around 81 mK and begins to drop. However, the fridge will soon begin to warm up unless a LHe transfer is performed. |
| 1300 | Commence LHe transfer (0%). |
| 1352 | Finished LHe transfer (91.5%). |
| 1541 | Mixing chamber temperature has settled down and stabilized to 77.6 mK with G1=87.3 mbar, G2=76.3 mbar, and P1=0.10 mbar. |
| 1745 | Fill LN2 cold trap full. |
| | Open condenser line speedivalve and gate valve. With dump pressure of 671 mbar, start manual condensation process through cold trap 1. Current 1 K Pot temperature 1.81 K. |
| 1810 | Removed 350 mbar of mixture from the dump. |
