| 0950 | Perform second room temperature electrical check. Everything appears normal, with small short to ground still apparent on DIB1. |
| 1030 | Seal up bottom of IVC. |
| 1040 | Commence pumping on IVC with scroll pump. Pumping through both stripline tube and top port. |
| 1110 | Switch to turbo pump to pump on IVC, with external pressure sensor reading 8.6E-2 mbar. |
| 1130 | Pumping pressure 7.4E-3 mbar (IVC >= 0.1 mbar with pump valved out) |
| 1200 | Pumping pressure 6.3E-3 mbar (IVC >= 0.1 mbar with pump valved out) |
| 1230 | Pumping pressure 5.4E-3 mbar (IVC >= 0.1 mbar with pump valved out). Leak background 290 E-9mbarL/s with pump valved out. |
| 1300 | Pumpout seemed low so did an initial leak check. Discovered that the valve to the check valve used for N2 backfill was not closed - oops. Closed this valve and switched back to turbo pumping. |
| 1315 | Pumping pressure 5.4E-4 mbar (IVC 2.5E-2 mbar with pump valved out) |
| 1425 | Conduct leak check on IVC and Ebox flanges, with a background leak rate of 3.0E-9 mbarL/s. No significant rise in leak rate was seen, indicating no room temperature leak. Switch back to pumping on IVC with turbo pump. |
| 1500 | Unpack G106a and perform electrical check. Elog entry here. |
| 1540 | Raise dewar. |
| 1605 | External pressure sensor reads 3.0E-4 mbar. Switch from turbo pump back to leak checker. |
| 1610 | Pump and flush main bath with He gas while conducting a leak check on IVC. Saw no rise from background leak rate of 2.1E-8 mbarL/s. Pump out 1K Pot. |
| 1615 | Start LN2 transfer. |
| 1630 | Pump fridge lines to dump |
| 1720 | MC (Cernox thermometer) 210 K (-10K/5min), Sorb 250 K, Still 210 K, IVC 1.9 mbar (4.6 mbar @ 300 K → <124 K), level resistor 1.233 kΩ (1Ω/10s) |
| 1740 | MC (Cernox thermometer) 180 K (-10K/10min), Sorb 228 K, Still 140 K, IVC 1.9 mbar (4.6 mbar @ 300 K → <124 K), level resistor 1.290 kΩ (1Ω/30s) |
| 1802 | MC (Cernox thermometer) 159 K (-10K/10min), Sorb 172 K, Still 108 K, IVC 1.6 mbar (4.6 mbar @ 300 K → <104 K), level resistor 1.320 kΩ (1Ω/60s) |
| 1810 | Finish LN2 transfer with level resistor at 1.330 kΩ and MC (Cernox thermometer) at 150 K. With G2=794 mbar and P1=15 ubar, stop pumping on fridge lines by closing gate and condenser line valves. |
