STATE of H1: Calibration
INCOMING OPERATOR: Travis
SHIFT SUMMARY:
LOG:

• Jenne and ThomasV were moving spots when a large shelf of noise started
• the noise lasted about 5-10 minutes, and cooincides with a large bump in noise on the 3-10HZ anthropogenic noise, though no proof that that was the cause
• H1 lost lock
• last 3 hours have been realigning H1
• arms locked in green nicely, but they are no longer aligned to the IR, so X arm in IR started locking at 0.3
• I had to move ITMX and ETMX at the same time in pitch and yaw to recover the X arm in IR
• had to center ASC QPD with SR2 to get SRC to lock
• in full lock, arms in green looked good, about 1.0, but COMM and DIFF beatnotes were way off, COMM was 2.2, DIFF at 1.2
• I used PR3 to bring COMM up to 4. something
• locking ALS locked well
• find IR had the X arm at 0.7 and Y arm at 0.5, so I tweaked PR3 to bring IR are signals up to were guardian would move on
• locked PRM, it was low, aligned it
• DRMI locked and ASC engaged, so hopefully this will make it to NLN
• handing off to Travis
