Looking at Niko's earlier lockloss from increase power, ( 1251472952 )and the most recent (sucsesful) power increase, it looks like in both cases the SRC1+SRC2 ASC loops aren't really keeping their error signals zero'd.  It also seems as though we might need to speed up the top mass offloading for SRM and SR2 (see attachment). 

I looked at increasing the offloading for this most recent lock, but the integrators are in the first filer module for SRM, I copied the top mass integrators for both SR2 + SRM to FM5.  I made the changes to use these later filters in the ALIGN_IFO guardian and laoded these changes.  I haven't finished by also changing ISC_LOCK because Niko made it to low noise and we are now observing. I've made but not loaded the changes in ISC_DRMI, and it looks like there are no changes needed in ISC_LOCK to move these filters (it just uses the settings set in ISC_DRMI).  The next time we are relocking we can load ISC_DRMI to move the integrators, so that we can try increasing the offloading gain.

STATE of H1: Lock Acquisition
INCOMING OPERATOR: Niko
SHIFT SUMMARY:  Currently attempting to relock.  Struggling to get much past DRMI locked. 
LOG:

13:30 Start IA due to PRMI not looking good.

14:50 OM2 WD tripped.  Cleared history for OM1 and OM2 Yaw Lock filter banks as both were railed.

No obvious casue.  Have been getting either EX or DCPD saturation alarms every hour or so, but not coincident with this lockloss.

While watching H1 relock I can see IM4 alignment chaging by around 60urad, so I searched O3, and see that in April the dirrefence was around 15urad, then in early May that drops to 5-6urad, then it's about 10urad, and by May 9th it's about 40urad.  It continues to change periodically, though remains at 40+urad, and currently the change is 60urad.  What's interesting is that the big change does not cooincide with the increase in power to 37W.   Plot shows IMC_IN and IM4 pitch, 150 days.  Chart shows changes every month, O3.

SHIFT SUMMARY: H1 in Oberve for about 4 hours, locking and relocking issues
LOG:

• first attempt at relocking after Initial Alignment - did not survive ENGAGE_SOFT_LOOPS
• second attempt made it to Observe
• third, forth attempts ended at ENGAGE_ASC_FOR_FULL_IFO
• Initial Alignment
• first and second attempts at relocking after Initial Alignment - did not survive ENGAGE_SOFT_LOOPS
• Initial Alignment
• handed off to Travis, H1 in Observe

No operator intervention required after IA completed (except for accepting SDF diffs).  Accepted IM alignment offset diffs that Cheryl changed (screenshot attached).

  • sat in ENGAGE_SOFT_LOOPS (435) for 17 minutes, until signals loked mostly flat over 140 seconds
  • then to NLN

STATE of H1: Initial Alignment

INCOMING OPERATOR: Cheryl

SHIFT SUMMARY: EQ lockloss from Observing, followed by a wind gust lockloss from Observing. Acquiring lock was having the same issues each time so decided to try and align the optics to their positions in the previous lock. Running initial alignment now.

LOG:

15:00 (08:00) Start of shift

16:06 (09:06) Going to EQ mode for 6.7 near Tonga

16:16 (09:16) Lockloss from EQ

17:00 (10:00) EQ rung down, attempting re-lock

17:41 (10:41) Lockloss from ENGAGE_SOFT_LOOPS. Looks like maybe a glitch.

18:11 (11:11) Lockloss from INCREASE_POWER. Going to try an initial alignment.

18:31 (11:31) Finished initial alignment, re-locking

19:12 (12:12) Locked at NLN, going to Observing. No SDF diffs.

20:19 (13:19) Lockloss, from a 40 mph gust of wind.

20:50 (13:50) Lockloss from ENGAGE_ASC_FOR_FULL_IFO, seems like another gust of wind.

20:51 (13:51) Running initial alignment, since I could barely get DRMI buildups above 50 last lock.

21:30 (14:30) Lockloss from ENGAGE_ASC_FOR_FULL_IFO. Going to try moving optics to their position in the previous lock and run initial alignment.

23:00 (16:00) End of shift

Lost lock at 16:16 UTC (09:16) from a 6.7 EQ near Tonga. After making it to ENGAGE_SOFT_LOOPS and INCREASE_POWER before dropping lock, I ran an initial alignment. As of 19:13 UTC (12:13), we are back in Observing.

SHIFT SUMMARY: locked all shift, 3 EQS, one was a 5.5 in Canada, and lock held
LOG: power cycled Video4, top monitor didn't power up, handing off to JeffB

The good news is that the PSL temperature is coming down.

Hugh and JeffB's alog that suggests a connection between PSL temperature and Tidal extremes, alog 51648, third plot.

The first plot shows that the Table North is sitll about 0.5F above the temperature before Thursday's work.

The second plot is from May, where the PSL AC was strategiacally turned off to put the temperature back as close as possible to the temperature before entreing into the enclosure, which was successful.

H1 in Observe, 3 EQS, and Tidal plots attached, Tidal is below 200000.
