FRS 10543
Verified ALS and PCAL lasers were keyed off.
~9am - Kyle, Gerardo, Chris Removed last 4 WBSC10 door bolts and removed the door
~9:20am - In-air, prior to anyone entering chamber, Fil performed HiPOT testing - ALL 5 ESD connections PASSED the 1kV test
~9:30am - Travis and Betsy entered chamber, locked the PUM mass, removed the CC horizontal witness wafer from under the QUAD
Test for continuity of all 5 ESD connections with Fil from the feed-through to the solder joints at the AERM (copper wire grounded to QUAD structure leg) - ALL 5 PASSED
~9:45am - Decided to repair LR connector anyway due to questionable hardware in the connector (incorrect sized inner pins)
ISI and Suspensions unlocked (except PUM carefully)
Disconnected connector after removed from PUM clamp
Wiggle test of pins and receptacles of the ESD connector - all seemed good, strong, not pushed in...
Cut off LR and performed retermination with all new parts per E1800147-v3, including new center pins, and proper crimping. Half of the work was performed wth my right and Travis' left hand since the short pigtail off of the AERM out the back of the QUAD had very little working room.
NOTE - Although there looked to be some crimping, Fil could easily pull off the outer sleeve PN-100909 from the receptacle. We did not see any other short symptoms such as wire fragments, over crimping, etc. (And, it passed today.)
~11:10am Finished retermination of LR and reassembly of connector, remounted in clamp, unclamped PUM, freeing ETMY reaction chain fully
~11:20am Rechecked continuity in same manor as above - ALL 5 ESD connections PASSED, Rechecked HiPOT at 1kV - ALL 5 ESD PASSED
~11:30am Gave the ETMy a quick N2 blow (barrel, gap, HR, AR as best we could without ACB swing back, etc. Saw the "typical" amount of particulate and features.
~12pm - Decided with Daniel to not "fix" remaining 4 connectors because 1) it was taking much longer to do with everything floating and 2) they aren't broken
Started transfer functions of ETMy Main and Reaction, and TMSy - all look ok
~1:30pm Hunted for chamber closeout signouts from cog engineers.
~2pm Door going on
