| 0000 | Pressure in P2 at 0.04 mbar. Switch off He-4 pump. |
| 0015 | Pressure in P2 rises to 0.07 mbar. The line has been evacuated. |
| 0045 | Cold traps are cool enough to place back into the LN2 bath. |
| 0100 | Fill N2 cold trap full. |
| | Pressure in IVC is 0.34 mbar. Evacuate IVC overnight. |
| 0230 | Cryoclean mixture. Valve 6 open 13.6%. |
| | Fill N2 cold trap full. |
| 1125 | Fill N2 cold trap full. |
| 1225 | Stop cryocleaning. Pump mixture into dump. |
| 1455 | Open valve 8 to pump mixture out of cold traps. Pressure of P1 rises from 0.012 mbar to 0.016 mbar. |
| 1600 | Pressure of P1 has dropped to 0.014 mbar; good enough. Extract cold traps from LN2 bath. |
| | P2 rises slowly compared with yesterday, but still saturates. Mixture might still be dirty. |
| | G1 rises as cold traps warm up. This is probably due to the leak in valve 12A. |
| | G2 reads 672 mbar, 10 mbar higher than yesterday. The different readings may be due to variation in the measurement gauge. This has been seen before. |
| 1630 | Expose cold traps to heat gun. |
| 1730 | Pressure of G1 oscillates between 0.0 mbar and 1.0 mbar. Try opening valve 2 to pump out line, but G1 refuses to drop. This might be a result of the relatively narrow diameter of the tubes, and this impedance makes it difficult to evacuate the line. |
| 1800 | Place cold traps back in LN2 bath and leave to cool. Stop pumping on traps and close valve 2. G1 rises to 1.0-1.3 mbar. |
| 1830 | Fill N2 cold trap full. Wait for cold traps to reach 77 K. |
| 2000 | Cryoclean mixture overnight. |
