TITLE: 04/07 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY:

HAM1 +y door removed (installed, thanks Betsy!) in the morning and Corner venting has begun (continues tomorrow).  h1seih7 was fixed and there was a daq restart for all the model changes from yesterday/today.  With the CDS work, guardian reboots, and other work which took SEI/SUS to non-standard states, everything looks mostly green on the OPS OVERVIEW for SUS & SEI.

1830-1920:  I stepped away to give a tour for kids on spring break and staff members of the Yakama Nation (Many thanks to RyanC for covering the chair in my stead).

• .2000 BSC2 & HAM6 in-rack work continued (fil)
• 2027 PCal Lab work (tony)
• 2028 Rebooting h1guardian1 for quarterly maintenance (tj)
  • ~2122  Jennie noticed on OPS OVERVIEW that we had 2W for JAC INPUT POWER.  This also probably restored 2W for input power.  Jennie took it to 0W
• 2045-2245 Vent prep & venting (travis, jordan)
  • 2123 Jordan brought in the checklist to address HIGH VOLTAGE items to address before venting:
    • Can't remember the verbiage, but there was mention of confirming "HEPI is safe".  Not clear what this meant, so I phoned Jim and he said take SEI Guardians to ISI_DAMPED_HEPI_OFFLINE. This was done for all Corner station SEIs.
    • For High Voltage, Jordan had this checklist document:  M1300464  (HEPIs are not listed in this document, btw):
      • Picomotors:  most of these were already disabled.
        • There were some which were enabled (1. SQZT0 and 2. HAM7 + SQZT7 ), these were disabled.
      • Ring Heaters---VAC team takes care of these on the floor.
      • SQZ OPO Tec:  SQZ OVERVIEW / TECs (blue button) / OPO from drop down ---> Servo already disabled.
        • Document (M1300464) mentioned this which was a little confusing:  go to the SQZ Overview & open the OPO dropdown (it's actually the TEC dropdown).
      • HAM1's already vented, but after Jordan chatted with Fil, decided to kill the PZT at HAM1 (for JAC?)
• ~2120-2150 ISCT1 was rolled back near HAM1---to clear up space for a garb room (ibrahim, randy)
• 2135 viewport inspection in optics lab(camilla, madi)....then off to CHeTA with Sophie...
• 2233 CHeTA lab work, local laser hazard (sophie, camilla, madi)
