Post O2 Planned Engineering

This Friday marked the end of week Fourteen of the Planned Engineering program of projects which commenced Aug 28th 2017. See chart below for outline and progress.

LLO Post O2 Vent Plan

The main achievements related to the work plan this week are:

The 70W laser amplifier installation at LLO is now complete

Further Squeezer installation work underway in HAM6.

More baffle installation.

The main activities for next week are:

Optical inspections, contamination control and discharge of the test masses

All going well having completed this round of in-chamber work the doors will be put back on and the vacuum team will commence pumping down the Vertex ahead of the holiday break

Observatory Computerized Maintenance Management.

FRS - Corrective Maintenance

Key Performance Indicator dashboard of issues tracked in the FRS.

FAMIS- Preventive Maintenance

LLO Tuesday Preventive Maintenance Work Orders 2017 (FAMIS)

L1 Commissioning
Valery Frolov

The installation of the squeezed light injection system is nearly completed and the commissioning has started. The in vacuum OPO has been locked and the autolocker has been implemented. The alignment and mode matching of the OPO beam to the interferometer output is in progress.

Squeezer engineering:

we continue testing the LHO cavity. We improved the mode matching for both wavelengths. We Performed higher order mode separation, escape efficiency and non-linear gain measurements, and are currently processing the data. Preliminary tests results are being compiled in DCC document E1700420.
