| 1255 | MC temperature 16.5 K, dropping slowly. Perhaps exchange gas was pumped out too soon. Check to see what situation is like in an hour. |
| | LHe level 63.8%. Might need to perform LHe transfer later today. Not sure if we have enough LHe for this weekend. It would be best to perform this transfer tomorrow morning. Check to see what situation is like in 6 hours. |
| | Pressure in IVC 4.6E-7 mbar. Most of the exchange gas has been pumped out. |
| 1315 | Fill N2 cold trap full. |
| 1800 | Start 1 K pot. We will fill the mixing chamber with mixture to act as exchange gas. Tower temperature is currently 14 K. |
| | Due to leak in valve 12A, mixture enters condenser line when valve 13A is opened. Therefore, we need to regulate with valve 9. |
| 2100 | Mixture is taking a long time to condense. Could this be evidence of the possible blockage witnessed during the throughput tests? |
| 2330 | Valve 12A fully open. Pressure in condenser line G1 = 125 mbar. Mixture still condensing. Leave to condense overnight. |
| | Fill N2 cold trap full. |
