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.
