Previous Day

1500 Assemble tower without detector or side coaxes for purposes of Megger testing the striplines+SQUETs+tower assembly.
1530 Install tower into fridge by attaching adapter plate to 30mK can.
1555 While installing the SQUETs, I had to remove the SQUET that was meant for DIB3 (side 6 of the tower) because I had not wound the stripline properly, which was preventing installation of the last SQUET card in DIB2 (side 5 of the tower). Upon removal, Pin (socket) 5 on side 6 of the tower, which has been loose for almost 2 years, broke away from the tower and remained mated to the pin 5 of SQUET card ZC-13. See pictures below:
Socket 5 from Tower Face 6 still attached to Pin 5 on SQUET ZC-13
Socket 5 missing from Tower Face 6
Removed SQUET ZC-13 from Stripline 20, and placed back in foil wrapping. Install SQUET ZC-70 to Stripline 27 and DIB2 (Tower Face 5), so that we have two striplines/SQUETs installed for Megger tests.
1630 Removed wire bonds from DIB1 Pin1 of G114. Attempted to make new wirebonds. Couldn't get bonds to stick. Attempted bond 1/2 powers of 460/350 and a little higher, 480/370, with the first bond to the DIB pad and the second to the wirebond pad on the detector.
