ISCT1 Bellows Back on, all LVEA lasers back on.

TJ, Camilla WP 12605WP 12593

As HAM1 is now low enough in pressure, we removed the HAM1 +Y yellow VP covers, re-attached bellows and removed guillotines. ISCT1 was moved back into place on Friday 84850.

After TJ transitioned to Laser Hazard, we opened the ALS and PSL light pipes and turned back on the SQZ, CO2s and HWSs lasers.  

After okay from VAC, IMC locked without issue, PRC and MICH alignments look good enough on AS AIR camera and we will begin realigning ISCT1 soon.
