| 1115 | Fill LN2 cold trap full. External pressure sensor on He-3 pump exhaust reads 22 mbar. Fridge temperature at 77 K. |
| | Close all valves on IGH. |
| 1123 | Switch from turbo pump to scroll pump and commence pumping on LN2 cold trap. |
| 1135 | G1=1.3 mbar, P1=30 ubar, and G2=6.3 mbar. Let in gas to G1 and P1. G1 rises to 999.9 mbar and P1 rises to 1000 mbar. Close V3 and pump out G1 until it reads <1 mbar. Close V2, V7, and open V1. G1 initially rose to ~200 mbar before starting to rise at a more steady rate. |
| 1145 | G1 is at 313 mbar and increasing with a flow rate of 32 mbar/min. |
| 1150 | G1 is now at 453 mbar and increasing with a rate of 28 mbar/min. |
| 1155 | Close gate valve and commence pumping out G1 and fridge lines with scroll pump. |
| 1250 | With G1=2 mbar, isolate turbo pump and open gate valve. G1 steadily begins to rise, with a rate of 27 mbar/min. |
| 1310 | G1=424 mbar and has a flow rate of 19 mbar/min that appears stable. Again, the experiment has to be aborted. Close gate valve and commence pumping on fridge lines with scroll pump. Once G1 < 3 mbar, switch to turbo pump. |
| 1441 | G1=1.5 mbar, isolate turbo pump and open gate valve. Flow rate of 19 mbar/min. |
| 1451 | To make the test more similar to traditional throughput, close V1 and give gas time to flow into fridge lines. In meantime, pump out on G1 till it reads 1 mbar. Open V1, and G1 has an initial spike before reducing to a steady rate of 17 mbar/min. |
| 1505 | G1 at 348 mbar with a flow rate of 13 mbar/min. Close gate valve and open V2 to commence pumping on condenser line and fridge lines. |
| 1620 | Close V1 and V2 to isolate pump. Open V1 and G1 rises to 15 mbar and starts rising at a steady rate of 10 mbar/min. |
| 1640 | G1=187 mbar and a flow rate of 8 mbar/min. |
| 1645 | G1 was at 207 mbar. Close V1 and open V3; G1 rose to 750 mbar, with P1=1000 mbar still. Fill LN2 cold trap full. |
| 1715 | Close V1 and open V7, V2, V11A and V3 to add more gas to the system. Once G1 rises to 999.9 mbar, and P1 still at 1000 mbar, close V11A and V3. Pump out gas in LN2 cold trap 1 and G1 lines until G1=0 mbar. Isolate G1 from scroll pump and open V1. G1 initially rises to ~200 mbar. The rate of flow into G1 then slowed to roughly 22 mbar/min. |
| 1725 | G1=503 mbar with a flow rate of about 16 mbar/min. |
| 1732 | Close V1 and open V2 top pump out G1. Once G1 down to 0 mbar, close V2 and open V1; G1 rises to ~500 mbar/min and then reaches a steady flow rate of 15 mbar/min. |
| 1750 | G1=728 mbar with a flow rate of 8 mbar/min. Open V2 to commence pumping on G1 line, fridge lines and P1 lines with scroll pump. |
| 1805 | Switch to turbo pump. |
| 1840 | G1=1.3 mbar, P1= 26 ubar. Close V3, V2 and V1 to isolate lines from turbo pump. |
| 1923 | Open V7, V2, V11A and V3 to add more gas to the system. Once G1 rises to 999.9 mbar, and P1 still at 1000 mbar, close V11A and V3. Pump out gas in LN2 cold trap 1 and G1 lines until G1=0 mbar. Isolate G1 from scroll pump and open V1. G1 starts rising from 0 mbar with a flow rate of 32 mbar/min. Open V2 to commence pumping on fridge lines with scroll pump. |
| 1933 | Switch to turbo pump. |
