TITLE: 03/05 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
OUTGOING OPERATOR: None
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 8mph Gusts, 6mph 5min avg
Primary useism: 0.01 μm/s
Secondary useism: 0.11 μm/s
QUICK SUMMARY:
Since Lunch time the control room has been enthralled with trying to relock H1 for the first time since Jan16th!
FIlter Tube Cavity is still closed.
LOCKING Notes:
TMS Alignment was tampered with before we realized that the Shutters were closed.
Using Camilla's alog with instructions on dithering alog 62024.
ALS Trouble Shooting before running TMS ITM and ETM Baffle Scripts.
ITMY Baffle PD4 was "Broken?"
Got light onto ETMY Baffle 1 and turned OFF the offsets to bring the light back to center then realigned ETMY via Guardian.
TMSX Baffle align script worked fine.
ITMX Baffle align Script failed to find any light.
But we didn't notice this and continued onto ETMX Baffle Align which found light.
Unfortunately this was NOT ALS light that we saw on ETMX. Sheila and I decided to Shutter ALS and the light we found on ETMX Baffle 1 did not go away when shuttering ALS shutter on X arm.
Troubleshooting ALS X some more: We then used the Oplevs from January to find a good spot to take ETMX.
First Light on ASLX 22:44 UTC
TroubleShooting PLL Problems that are making the X arm hard to lock. Eventually I got the ALSX beam spot looking as good as I could and then paused while Ryan S checked out the PLL.
Ryan S found out that the Beckhoff reboot turned off ALSX fiber Servo compensation. Checking out the SDF there was a dead give away that the problem was caused by a Beckhoff reboot. The date of the Change was Sun Dec 31 16:00:00 1989 which was the big clue.
DigiVideo3 Needed to be rebooted again.
Technical Notes:
ETMX Oplev positions AFTER we have good ALSX beam Spot:
H1:SUS-ETMX_L3_OPLEV_PIT_OUTPUT = -5
H1:SUS-ETMX_L3_OPLEV_YAW_OUTPUT = -12
ITMX Oplev positions AFTER we have good ALSX beam Spot:
H1:SUS-ITMX_L3_OPLEV_PIT_OUTPUT = -7
H1:SUS-ITMX_L3_OPLEV_YAW_OUTPUT = -1
ETMY Oplev positions AFTER we have good ALSY beam Spot:
H1:SUS-ETMY_L3_OPLEV_PIT_OUTPUT = -16
H1:SUS-ETMY_L3_OPLEV_YAW_OUTPUT = -13
ITMY Oplev positions AFTER we have good ALSY beam Spot:
H1:SUS-ITMY_L3_OPLEV_PIT_OUTPUT = -13
H1:SUS-ITMY_L3_OPLEV_YAW_OUTPUT = 9
Comm Beat note: 1.5
Diff beatnote : -14
The Beam splitter was touched up as well.
BeamSplitter Oplevs as they currently Stand:
H1:SUS-BS_M3_OPLEV_PIT_OUTPUT = 7
H1:SUS-BS_M3_OPLEV_YAW_OUTPUT = -9
Dark offsets by hand , for AS_C.
PR2 and IM4 were just touched up and then did Dark Offsets by hand for POP 45.
PR2 Witness sensors positions:
H1:SUS-PR2_M3_WIT_LMON = -29
H1:SUS-PR2_M3_WIT_PMON = 614
IM4 Witness Sensors postions:
H1:SUS-IM4_M1_DAMP_L_INMON = -41
H1:SUS-IM4_M1_DAMP_P_INMON =-2803
X ARM Sensor Correction has been turned off the Entire time due to Jim's BRS being rung up by him working on it.
