LIGO Laboratory Safety
Albert Lazzarini (Richard Oram, Bubba Gately)

The monthly meeting of the Safety Steering Committee was held this past Thursday. Minutes have been posted on the Laboratory Safety Web Page (access restricted).

Safety message for the week: Please take the time to report any unsafe condition that you may run across – and turn it into a Good Catch.

H1 continues to run at lower sensitivity due to Montana Earthquake from a few weeks ago & we run at a BNS Range of ~53Mpc. The cause of the range decrease is still under investigation.

H1 Commissioning

No commissioning due to O2.

H1 continues to run with higher noise than pre-earthquake with BNS range of ~55Mpc. Noise investigation continues.

Jitter coupling is there, but even after jitter subtraction, something else is hurting our performance between 20Hz and 100Hz (alog 37590).

Observing Run #2

LLO achieved a weekly uptime performance (Weds-Weds) of just over 63% @ around 95 - 100 Mpc BNS range. Main causes of time loss this week were due to commissioning, locking acquisition, and corrective maintenance.

Recall that O2 commenced 10:00 am CT Nov 30th 2016. As of Friday, (33+ weeks or 5302 hours) into O2, Overall L1 operation has achieved a cumulative uptime of around 58.9%.

L1 cumulative uptime since the start of O2 is shown in the very useful performance charts

Observing Time Loss due to HW/SW/ procedural faults

Summary of LLO Corrective Maintenance issues that have caused Observing Time Loss

We lost about 9 hours of observing time this week due to faults that required corrective maintenance.

70W Laser Amplifier

Following a field service Visit by NeoLASE the 35W Front End Laser was successfully realigned and was returned to nominal operating performance. This enabled the work on the NeoVan4s (70W) amplifier to continue. See relevant alog entry:

The FE and amplifier combo are producing 70+ Watts (actually around ~79W) and is now being continuously run in LLO Laser Test Lab for the next few weeks to verify power stability. Laser workers continue to characterize the beam quality and pointing etc.

Tuesday Maintenance Period Work Permits opened and or executed this week.

FAMIS- Preventive Maintenance

Note: LLO has shifted the maintenance period back by one hour. From now on it is scheduled from 9:00 am until 1:00 pm (local time) instead of 8:00 am until 12:00 pm.

Tuesday Work Permit Summary

LLO Tuesday Preventive Maintenance Work Orders 2017 (FAMIS)

Preventive Maintenance activities that were scheduled for execution during the month. LLO now schedules and executes over 200 preventive maintenance work orders each month. LHO now schedules and executes ~ 100 preventive maintenance work orders each month.

O2 Run

The interferometer has been running well with a BNS range that often exceeds 100 Mpc. Duty factor has been between 60% and 70% impacted mainly by commissioning and some hardware problems.

  1. Continuing squeezer hardware build. Summer Engineering Intern (Damian Lavin) continues to test the 384 channel Acromag Binary IO chassis.
  2. Luis is producing the final datasheet data for the PDH box he has produced and transitioning to working on the IO chassis upgrade.
  3. Todd has finished testing last remaining VOPO suspension Coil Drivers for Squeezer. He is now transitioning to AA board manufacture.
  4. Ordered (with help from Marie Woods) prototype electrometer circuit boards for in-vacuum electric field probe to be delivered to Rai.
  5. Working squeezer wiring library parts.
  6. Submitted in-vacuum wiring build to outside vendor for quote.
