Optical Lever Work (WP 5296)

J. Oberling, E. Merilh

We swapped the oplev laser for ETMx; power cycling the laser did not improve its behavior.  Old laser SN 197, new laser SN 106-1.  The old laser will be bench tested to see if we can find out what's wrong and if there's anything we can do about it here (possible return to MicroLaser)

We installed the 50lb lead vibration absorbers on the ITMx and ITMy oplev receiver piers.  The ITMx oplev did not need to be realigned after the installation; we did however realign the ITMy oplev after installation.  All lead vibration absorbers are now installed at LHO (ETMx, ETMy, ITMx, ITMy).
