| Status | Run 77 in progress |
| Setup | Cable 2/1/3 → diverter/nothing/nothing → DCRC50(3)/DCRC55(1)/DCRCX(4) |
| 1050 | Fill LN2 cold trap dewar |
| 1118 | Switched the DCRCs to Run 76 order Cable 2/1/3 → diverter/nothing/nothing → DCRC 1/3/4 |
| 1135 | DCRC1 on Cable 2. PA and PD not responding to Signal Generator/ show any traces. Changed SQUID bias/QET bias and lockpoint. |
| 1140 | DCRC3 on Cable 1. No channels responding. |
| 1145 | DCRC4 on Cable 3. o channels responding. |
| | Begin another warm up and pump out |
| 1151 | Close V6 to stop circulation. |
| 1156 | V6 is now fully closed (light is off on IGH, Still pressure is rising, Condenser pressure falling). Turn off 3He pump |
| 1158 | Close IVC valves on top of the fridge, I do this so that when we are at 10K we can check the contents of the IVC. |
| 1200 | Close 1K Pot needle valve |
| 1200 | Open V3 to let mixture from Condenser side into Still side. |
| 1205 | MC = 0.43 K |
| 1206 | Turn off DAQ programs and unplug DCRCs 1&3 |
| 1208 | Turn on Still and MC heaters to 20 mW each |
| 1210 | Close 1K Pot speedivalve, V4a, 4He pump inlet valve. Turn off 4He pump. Close recovery valve to 4He pump outlet. NOTE: remember to open recovery valve when the pump is turned back on. |
| 1230 | MC(H35)/1KPot = 3.90/3.86 K |
| 1230 | G1(fridge) = 780 mbar. Open V9 to release mixture into dump |
| 1243 | MC temp starts to rise more quickly |
| 1245 | MC(H35)/1KPot = 4.78/4.33. Temperatures are relatively flat now. |
| 1250 | Check pressure in IVC: 0.54 ubar. |
| 1325 | Run the leak checked on the IVC, leak checker base = 0.2 pbar*L/s, leak checker on IVC peaked at 6.3 ubar*L/s |
| 1328 | Pump out IVC with the turbo pump, mc temp starts to rise again |
| 1607 | MC = 10.0 K. Turn off MC and Still heaters |
