| 0958 | Fed Cricket 3 pellets. |
| 1015 | Filled LN2 cold trap. |
| 1325 | Helium in main bath has run out. Mixing chamber temperature 1.0 K. Pump mixture into dump. |
| 1410 | Stop 1 K pot. |
| 1600 | Removed Poly-lead shield. |
| 1640 | Fed Cricket 4 pellets. |
| 1850 | Turn on mixing chamber heater, power 10.0 mW, to aid extraction of mixture. |
| 2005 | Mixing chamber temperature 7.9 K, dump pressure 711 mbar. Switch off mixing chamber heater. |
| 2130 | Mixing chamber temperature 7.6 K. Helium leak rate in pipes leading to IVC 7.1E-10 mbar l/s. Open up IVC and helium leak rate jumps to 2.2E-5 mbar l/s: and order of magnitude higher than expected. Is it possible that there is indeed a superfluid leak and we did not leave the mixture in for long enough to actually see it in our previous tests? Let's see what the leak rate is at a higher temperature. |
