STATE of H1: Lock Acquisition
INCOMING OPERATOR: Jeff
SHIFT SUMMARY: Lockloss might be from an earthquake in Japan. Still struggling to relock. After two lock losses in the CARM reduction states, moved to initial alignment. Could not get SRY to acquire in initial alignment and gave up on it to try relocking again. I moved the SEI_CONF state from USEISM to WINDY because the green arms were more stable in WINDY, but have now set it back to USEISM.

INCOMING OPERATOR: Patrick
SHIFT SUMMARY: H1 lost lock due to  local EQ, relocking had some issues, listed below, currently H1 has been in Observe for almsot an hour.
 

Relocking/Shift Highlights:

• trouble locking ALS Y
  • locked and aligned by starting in LOCKED SLOW NO WFS
• PSL power seems to have dropped, so not giving 2W at low power
  • I used the Rotation Statge calibration to get past this at low ppower
  • I set the calibration back to it's nominal value before INCREASE POWER
• ALS Y fiber polatrization went bad
  • I used the "RESTORE" feature, which brought the polarization down to 16%
• Turned off AC to fiber polarization, later than optimal, though I blelieve no change to H1
  • at 00:12:25UTC, while talking to Patrick, I realized that I had left the ALS AC power to adjust the polarization ON, so turned it off
  • did not go out of Observe, since H1 is not using ALS at the moment

Relocking LOG:

STATE of H1: Observing at 117Mpc
OUTGOING OPERATOR: Cheryl
CURRENT ENVIRONMENT:
    SEI_CONF state: USEISM
    Wind: 7mph Gusts, 5mph 5min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.76 μm/s 
QUICK SUMMARY: Microseism is still high. No other issues.

H1 knocked out of lock by a 3.6M EQ in Packwood, WA, about 140 miles from the site.

I've been damping violin modes, and the ndscopes for each mode on an optic are very helpful, and since I need to watch more than one mode.  I've updated the ndscope files for:

1. ITMX mode 13, first attachment, I added the gain to the top plot, which also has the output
2. ITMX mode 17, second attachment, I added the gain to the top plot, which also has the output
3. ETMY mode 12, third attachent, I added the gain to the top plot, which also has the output, and I added a third plot, which has ETMY modes 18 and 20.
   • my observation about mode 18  is that it suffers little to no ill efects by damping mode12
   • my observation about mode 20  is that rings up as mode12 is damped, however, the increase in RMS is slow, and typically small

• There was a small dusting of snow on Route 240 and Route 10 this morning, no impact to driving, and a bit deaper snow on our driveway, less than an inch, but still enough that when testing the road, I could get my car to slide.

13:04 Attempt #1

• Lockloss at ACQUIRE_DRMI_1F

13:15 Attempt #2

• Lockloss at ACQUIRE_DRMI_1F

13:33 Attempt #3

• Lockloss at LOCKING_ALS

13:36 Attempt #4

• Lockloss at ACQUIRE_DRMI_1F

13:43 Attempt #5

• Going to manual MICH_FRINGES and PRMI
  • Flashing looks ok to me
  • PRMI Successful
  • DRMI locked successfully
• Lockloss at CARM_OFSET_REDUCTION

14:08 Attempt #6

• Lockloss at ACQUIRE_DRMI_1F

14:23 Attempt #7

14:56 NLN

15:00 H1 Observing

So, at my last mention of Initial Alignment, a lot has transpired.

• WFS kept driving ALSY out of lock
  • DOF 2 off stoppped that and allowed me to step TMS back in pitch to the zero crossin where I re-enabled the DOF 2 WFS which just screwed it up again
  • I, then , manually locked ALSY and offloaded the green WFS in order to attempt another IA

10:04 I ran Initial Alignment

10:18 I attempted to re-lock

• 10:20 FSS trouble started
  • it became unlocked and despite my efforts I couldn't get it nor the IMC re-locked
  • 10:30 I succumbed to call Jason and he helped me to resolve the issue

10:43 back to attempting to re-lock

• IFO still in SEI_CONF = USEISM

10:57 Lockloss at TURN_ON_BS_STAGE2

11:00 Attempt #2

• Lockloss @ CARM_OFFSET_REDUCTION

11:14 Attempt #3

• made it to INCREASE_POWER . As I was investigating why the power increase wasn't happening I acidentally clicked a button on the laser power guardian. grrrrrrr

11:47 Attempt #4

• Lockloss @ CARM_OFFSET_REDUCTION
• Got rid of nagging LASER_PWR notification by executing te Search for Home on the Rotation Stage MEDM screen

CURRENT ENVIRONMENT:
    SEI_CONF state: WINDY
    Wind: 9mph Gusts, 7mph 5min avg
    Primary useism: 0.05 μm/s
    Secondary useism: 0.75 μm/s
QUICK SUMMARY:

• Microseism is a bit ridiculous hovering around 1um/s by the looks of the BLRMS
• Patrick's latest attempt at re-lock failed at the usual CARM_OFFSET_REDUCTION
• ALSY looks pretty bad so I'm going to make 1 more attempt to salvage th existing alignment under these shaky conditions
  • if my attempt fails I'll do Initial Alignment

      • gain increased to 20.0 @ 20:43:08 UTC, the drive did not increase, indicating saturation, so I went back to a gain of 15
      • gain increased to 15.0 @ 20:44:18 UTC
      • since ETMY mode 12 has had reports of being difficult to damp, I ramed up the gain very slowly
      • it's possible that the saturation with gain = 20 caused some additional noise in DARM
• final attachment shows the decrease in RMS from tonight's violin mode damping
