Ops Day Shift Summary

TITLE: 06/01 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: Very busy day with lots of visitors on site! Essentially everything was recovered following the weekend power outage, doors on HAM7 were removed and SQZ work in the chamber started after the ISI was locked, QOSEM work continued on the BBSS, the ISI was balanced on the test stand, prep began for the ITM cage baffle installation, GV7 was cycled and left closed for venting of the X-manifold, more beam alignment went on in HAMs 2 and 3, turbopumps at EY and MY were tested, FARO surveying began in HAM3, CRS building continued, and SPI work in the optics lab is ongoing. The EDC is still showing several disconnected channels, some of which relate to EY dust monitors.
