0950 Start assembling G51
1002 Checked all channel to ground, no shorts found on the detector
1019 Put G51 and tower back to N2 purge. It's best to take a picture of G51 before assembling.
1102 Got an camera, resume assembling tower. Need WIP-0609 cleanroom wipes. Need to turn down N2 pressure.
1127 DIB1→Face2(ZB-5)→ZIB1-1-6, DIB2→Face5(ZB-8)→ZIB1-1-9
1135 Need a new screw for thermometer.
1318 Tower assembled and double bagged and sitting in the clean room.
