All is well. Bag up tower and bring to clean tent for installation.
| 1130 | Tower successfully installed to 30mK can. DIB1 is facing East, DIB 2 is facing West. |
|---|---|
| 1245 | Thermometer wire connected and taped. 100mK rings and heat-sinks connected. |
| 1458 | During installation, noticed Stripline 19 cold end diverter board had a bent pin 7. Pin bent back into place before proceeding. Pictures below. |
| 1605 | Install SQUETs, with ZC-39 on DIB 1/Stripline 19 and ZC-13 on DIB2/Stripline 27, and conduct electrical check. Everything looks alright. Continue with installation. |
|---|---|
| 1730 | Close check valve. Seal up IVC and begin pumping on IVC with scroll pump. Turn on turbo pump. |
| 1845 | At IVC pressure of 4.6E-2 mbar, switch to turbo pump. Pump out IVC overnight. |
