HAM4 Closed out

Betsy, Travis, bit of Kissel, Bubba/Tyler/Mark

 

Already eluded to in previous alogs, but HAM4 has been closed.  The usual steps were taken:

- ~9:30am  Lay/mount 3' witness wafers

- Wipe table and ISI reachable surfaces

- Pull FC previous painted on SR2 and HWS DCBSx and DCBSy

- Unlock SR2 SUS and lock down nuts

- Checklist E1201035 checked throughout this to check for tools, dust counts, etc.

10:50am  Dust counts at S door during this activity with Travis and I near the door were:

0.3u  80

0.5u  40

0.7u   0

1.0u  30

- Run quick 6 DOFs of SUS (some troubleshooting needed - cables recheck by Fil OK, BIO state needed switching, vertical stops needed resetting since apparently rattled down during 5mm slide, TFs finally pass)

- Unlock ISI

- SEI discuss and quick medm check ISI, pass

- Hunt down the Signoff sheet on DCC, then found it to be out of date, spent 30mins hunting people down - people either weren't the appropriate people to sign, or were on travel.  Vern is updating sheet and reprinting for future chambers.

- Doors attached ~12-1.
