| | overnight: Stopped circulation for the weekend due to unstable 1K pot. |
| 1101 | Tower = 1.56 K, G1/G2 = 25/23 mbar, MB=39.6% |
| 1110 | Start LHe transfer, MB=39.6%. Due to He shortage, don't precool transfer stick. Instead of waiting for the plume, only waited ~10s so all air could flow from transfer stick. This was a much more violent start than normal, the recovery meter went crazy for about 3 minutes. Wait until it settles down to a normal rate to pressurize the dewar. |
| 1115 | Fill LN2 cold trap full. |
| 1155 | Cease LHe transfer, MB=92.8%. |
