| 0920 | P1=280 ubar, G1=26 mbar, G2=668 mbar. Fill LN2 cold trap. Open V9, V5, V12A, V12B and cold trap speedivalves to pump out any remaining mixture. |
| 0947 | When G1=0.0 mbar, P1=16 ubar and G2=666 mbar, close all valves on the IGH. Then pull LN2 cold traps from bath and open to P2 (scroll pump speedivalve closed). Allow to warm up. |
| 1028 | P2=85 mbar. Open scroll pump valve to pump on cold traps. |
| 1045 | Finish first round of cold trap cleaning. |
| 1120 | Finish second round of cold trap cleaning. |
| 1142 | Isolate LN2 cold traps, and place back into bath. Fill LN2 cold trap bath full. |
| 1150 | Commence cryocleaning through cold trap 2. |
| 1250 | Cease cryocleaning and pump mixture to dump. |
| 1320 | All mixture in dump, G2=669 mbar, G1<1 mbar, P1=6 ubar, mixing chamber at 16.7 K, Sorb at 17.0 K. Isolate dump, close all valves on IGH. Pull cold trap 2 from LN2 bath and open to P2 (scroll pump speedivalve closed). |
| 1355 | P2=14 mbar. Pump out with scroll pump for a moment, then isolate cold trap 2 (to be cleaned later). |
| 1400 | Open gate and condenser line speedivalves, P1 rising from 9 ubar to 20 ubar. G2=667 mbar. Temperatures of still and mixing chamber are the same as 1320. Commence throughput test. Allow mixture to flow through cold trap 1 to G1 and P1 until G1 stabilizes at 515 mbar. Close V12A, cold trap 1 speedivalve and V3, open V1 until. G1 drops to 151 mbar before rising. Flowrate of 85 mbar/min found. Pump mixture to the dump. |
| 1420 | G2=668 mbar. Commence throughput test. Allow mixture to flow through cold trap 1 to G1 and P1 until G1 stabilizes at 510 mbar. Close V12A, cold trap 1 speedivalve and V3, open V1 until. G1 drops to 150 mbar before rising. Flowrate of 90 mbar/min found. Pump mixture to the dump. |
| 1440 | Cold trap 2 has been out of bath and warming. Open cold trap 2 to P2 (scroll pump speedivalve closed). P2 rises to 2.5 mbar after a few minutes. Open scroll pump speedivalve to pump out. Isolate cold trap 2 after a few minutes. |
| 1445 | Start 1K Pot. Mixing chamber temperature at 16.6 K, Sorb temperature at 4 K, 1K Pot temperature at 1.74 K, G2=668 mbar, G1=1.8 mbar, P1=17 ubar, P2=24 mbar. Commence condensation procedure through V1 ans V3. |
| 1533 | Open 12A all the way. Mixing chamber temperature 2.2 K, G1=121 mbar, G2=182 mbar, and P1=1000 mbar. |
| 1542 | G1=75 mbar, G2=83 mbar. Start circulation procedure. |
| 1633 | After several hours or turbo pumping on LHe transfer stick vacuum jacket, isolate transfer stick. |
| 1635 | Open V6 fully. |
| 1715 | With P1=600 ubar, close V14. |
| 1735 | Mixing chamber temperature at 398.2 mK, 1K 1.737 K P1=200 ubar, G1=124.8 mbar G2=133.3 mbar, P2=34 mbar. Perform single shot test. |
| | Performing single shot test resulted in steep rise in mixing chamber temperature and a fall of P1 to a somewhat stable value of 22 ubar. |
| 1752 | Stop 1K Pot and commence pumping mixture to dump from both sides of fridge. |
| 1958 | Mixing chamber at 16.5 K, G1= 0.3 mbar, G2=669 mbar, P1=9 ubar. All mixture has been collected from the fridge lines. Close gate valve and condenser speedivalve. Turn off mixing chamber heater. Close V6. |
| 2011 | Close all valves on IGH and cold trap 1 speedivalve. Mixing chamber at 16.2 K and dropping. |
