| 0847 | MC X12004=83.5K, IVC pressure:0.19mbar, cryocleanning is still going |
| 0933 | Fill N2 cold trap full |
| 1328 | Pumping N2 exchange gas out, found He-3 exchange gas manifold NW16 inline valve left open, closed it, no leak found on the pumping lines, MC x12004=78.6K |
| 1336 | IVC pressure: 3.4E-5 mbar |
| 1411 | Isolate pumping station, IVC He background signal 1.4E-8cc/s, 1.6E-9cc/s with the pumping station connected. |
| 1427 | Electrical check at 78K, results. |
| 1454 | Stop cryocleanning, pumping mixture into dump |
| 1547 | Throughput test at 77K, 540mbar at still line, G1 increasing rate: 33mbar/min, no leak found at BG 6E-10cc/s with pumping station connected |
| 1601 | Start to blowing out liquid N2 |
| 1723 | G3 pressure starts to drop, liquid is out, no leak found at BG 1.25E-8 cc/s |
| 1733 | Pump the he bath |
| 1754 | see a he signal rise when fill the bath with He gas |
| 1811 | pump he gas in the bath out and see if the he signal drops |
| | The he signal of IVC drops when pumping on the bath, there is likely a leak between the bath and the IVC |
| 1817 | P2 reaches 1mbar, fill the bath with He gas again, the he signal of IVC rise again. There is a leak between the main bath and the IVC. |
| 1838 | Fill the bath 73.4 mbar over pressured He gas, IVC he signal 4.2E-5 cc/s with pumping station isolated |
| | I'll warm the fridge up and see if the leak is still there at room temperature, if the leak is still there, then drop the dewar, find the leak, and fix it; if the leak disappeared at room temperature, then fill the bath with liquid N2 again and position the leak while blowing liquid N2 out. |
| 1858 | Put ping pong ball on the He recovery port, put in 0.5mbar N2 exchange gas into IVC. MC X12004=78.1K. I'll let it warm up |
| 1934 | Dropped the dewar to warm up the fridge faster |
