TITLE: 08/25 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:
Very Busy Maintenance Day at the End Stations and the Corner Station. The biggest update is that ALSY now reliably works with WFS Converging! As such, PRMI has been locked consistently with some instability in the BBSS. Commissioners Elenna and Louis are working on improving it in various ways.
Broken down by station
EX:
PCAL Measurement - Tony and Caroline (PCAL)
- Start Time: 9:55
- End Time: 12:35
- Details: Needs EX Hazard, ETMX Aligned
- Summary: Success!
- Links: WP 13545,
ETMX BOSEM Measurements and Troubleshooting - Oli, Fil, Betsy (SUS, EE)
- Start Time: 10:15
- End Time: None
- Details: HEALTH_CHECK state needed for EX Transfer Functions.
- Summary: The TFs taken seem to indicate rubbing in the transfer functions, but OSEM trends seem to imply otherwise. We are still somewhat confused as to what is exactly going on here. This problem has grown to a larger issue that will involve many alogs - will try and update this Alog with these when they come in.

EY:
UPS Access System Replacement - Fil (EE)
- Start: 9:50
- End: 11:40
- Summary: Success!
- Links: WP 13544
Beckhoff Chassis Swap, Repair ALSY WFS Demod RF Level Monitor - Marc (EE)
- Start: 8:40, back out at 11:05 with new ideas
- End: 10:40
- Details: Put SUS_ETMY in SAFE and ETMY ISI in DAMPED as a precaution. Readbacks for two channels are malfunctioning for power in the local oscillator. Troubleshooting pointed to Beckhoff, but a chassis swap seems that this did not fix the problem. Marc has a hunch that he will potentially chase.
- Summary: Success - faulty connector.

Corner:
Gate Valve, Leak Check and Output Tube Gauge Work (Gerardo, Jordan, Travis)
- Start: 8:40, 11:30 (leak checks HAM7)
- End: 10:45 (For Gate Valve and Output Tube Gauge work), 12:00 (Leak Checks HAM7)
- Summary: Success
- Links: WP 13549,
TCS Line Inspection and TCS Inventory Work (TJ, Christina, Camilla)
- Start: 9:20
- End: ~11
- Details:
- TCS lines need to be inspected. TJ found glycol dripping along one of the lines that go back to the chiller from the mechanical room. He and Jim are working on removal.
- There are old parts and pieces, including an old TCS chiller in the LVEA. These need to be disposed of and inventoried.
- Summary: Success
- Link: Alog 91675, Alog 91674
ITMY Optical Lever Relocated for CHETA:
CDS:
Work stations rebooted
Control Room Screens:
- Control room screens had various issues but these were fixed by Erik and Jonathan
- NUC 28 had a full disk preventing operator control and crashing the computer
- NUC 20 did not come back after the work station reboot and had to be turned on and manually set up
- NUC 30 had to be reset
- NUC 5 plots froze for a bit but a refresh is all it took
Vacuum Electronics Work (Patrick, Jordan, Gerardo, Travis)
- Start: 8:00
- End: 12:40
- Details: Update the configuration and PLC code on H0vaclx to change the BSC8 PT180 gauge from a BSG 450 to a BSC552. This takes the LX Vac readback down for a period of time. DAQ Restart Required After
- It got delayed, with cooperation with the Vacuum team needed to troubleshoot PT110 (HAM6).
- Links: WP 13532, Alog 91676
- Summary: Success. Only 1 DAQ restart was needed, which was taken care of by Dave and CDS as part of their restart.
CDS DAQ Restart (Dave):
- Start: 12:35
- End: 12:45
- Details: Remove the decommissioned h1daqscript0's CDS LOAD MON channels from the EDC. DAQ+EDC restart needed on a target-of-opportunity. If they can time it with Patrick’s Vacuum Electronics work, then there would only be one restart needed. However, since VAC EE took time, they couldn’t do the restart and by the time they wanted to do their own restart, Tony and Caroline were in the middle of their PCAL measurement at EX. Thus, they are planning to do the restart at around noon, when PCAL is expected to be done. Requires BBSS in SAFE
- Summary: Success!
- Links: WP 13542, Alog 91671
IOC Container Host Cluster Update (Jonathan):
Commissioning/Ctrl Room Work - Started at 12:40 (approx.)
- ISCT1 POP Power Measurement - Alog 91657
- BBSS Damping Loop Lowpass Changes - Alog 91656
- ALSY Locking with WFS - Works!
- ALSX gameplan following ETMX findings of rubbing - Alogs coming soon because this rabbit hole turned into a mole network. - Alog 91678
- PRMI Locking - Works but commissioners are improving it
