FAMIS 11527

I think I accidentally put too much water in the TCS Y chiller. I didn't see it do anything abnormal though.

TCS X
Before: 28.9
After: 30.5
Added: 150 mL

TCS Y
Before: 9.3
After: 10.8
Added: 100 mL

End-Y - Trip level was lowered to 8 10/16. The level is 8 14/16 - No change from last check.
End-X - The level is 7 14/16 - No change from last check. 
CS - The level is 6 6/16 - No change from last check. 
No new leaks were observed on any platforms.

TITLE: 01/21 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
OUTGOING OPERATOR: Cheryl
CURRENT ENVIRONMENT:
    SEI_CONF state: SC_OFF_NOBRSXY
    Wind: 5mph Gusts, 3mph 5min avg
    Primary useism: 0.04 μm/s

Maintenance Begins!

Looks like X-arm access is clear all the way to EX except for a pile right at EX (tyler/scott are on it).

STATE of H1: Preventive Maintenance
INCOMING OPERATOR: Corey
SHIFT SUMMARY: locked most of the shift, relocking took a while, H1 reached NLN and then I ran the PEM injections (cold H1)
LOG:

• 08:02:40 - airplane heard in CR
• 09:53:58 - SEI to EQ
• 10:27:41 - SEI to WINDY
• 11:54:21 - SEI to EQ
• 12:18:55 - SEI to WINDY
• 15:44:52 - NLN
• 15:45:00 - (yes, 8 seconds later) verbal alarm for PEM injections, which I started within a few seconds
• 15:51:37 - Scott and Tyler starting the big green monster and then going to MX
• 15:56:12 - PEM injections are done
• 15:58:18 - Sheila to the optics lab
• 16:00:54 - lockloss, Maintenance

locked in Observe, 2 EQs, EQ mode, damping ETMY violin mode 20

TITLE: 01/21 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 119Mpc
OUTGOING OPERATOR: Ed
CURRENT ENVIRONMENT:
    SEI_CONF state: WINDY
    Wind: 4mph Gusts, 3mph 5min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.45 μm/s
QUICK SUMMARY: H1 locked in Observe

• Last night and throughout today we've continued to have low level MY Air Handler Reheat alarms, when the temperature goes over 100F, however, plots show that the temperature returns to a reasonable level in a short amount of time, and shows that MY VEA temperature is stable at around 70F.   The alarm is intended to alert us that the chiller(s) have tripped off, but in this case the chillers are oporating as expected.  Plot attached show 20 days of AH REHEAT, VEA average temperature, and outside temperature.

TITLE: 01/21 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 116Mpc
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY:
LOG:

• Shift was relatively quiet - H1 had decent range
• 1 lockloss that required an Initial Alignment for recovery as per the Intervention protocol
  • details in Lock Acquisition data
• handing off to Cheryl

LOG:

Wasn't going to jinx myself by logging that everything was ok.....until:

04:13 Lockloss - no apparent reason - initiating recovery now

DCHILFLOW seems to be "slinkying" it's way down the "stairs". I suppose eerything else looks ok. Camila had the FSS go into oscillations on her twice during an initil alignment (during PRC align, i believe).

SHIFT SUMMARY:Spent some time struggling to get back to NLN after lockloss (not sure reason for lockloss yet), and calebration measuremnets in the afternoon.
LOG:

• 16:06 Lockloss see details and SDF diffs in alog 54597
• 18:11 Dick on site
• 19:24 Observing.
• 21:30 Starting planned Calibration measurements as described in alog 54557
• 22:45 Back to Observing

CP6 Dewar level started alarming at 15% full. We have an LN2 delivery scheduled for Wednesday now that X1 is clear of tumbleweeds, and want to avoid Dewar level falling below 10%, at which point contaminate (ice crystals) buoyancy level meets CP supply line and thus potential for ice plugs is high.

Ignore alarms for now. LN2 consumption averages 1.2% per day.

• 16:06 Lockloss
• 16:12 SEI_CONF to WINDY
• 17:09 SEI_CONF back to USEISM as lots of locklosses
• 17:10 Cleared OM1 and OM2 LOCK FILTERS histories as these were suspensions were saturating.
• 17:43 After 3 locklosses in CARM reduction states, ran initial alignment (as operator intervention thresholds suggests)
• 17:59 FFS unlocked during INITIAL ALIGNMENT in state PRC_ALIGNING (toggled auto-locker on 00 mode)
  • This happened during inital alignment in the same PRC_ALIGNING state yesterday (alog 54583 20:31 UTC)! tagging PSL
• 18:43 SEI_CONF to WINDY
• 18:45 FFS wouldn't lock (toggled auto-locker on 00 mode)
• 19:21 NLN
  • CALCS rounding errors SDF diffs accepted
  • Same ETMX_M0_TEST_P/Y_OFFSET SDF diffs as yesterday reverted - see attached (something to do with initial alignment not reverting them maybe?!)
• 19:24 Observing.

Attached is a dtt file with measured transfer functions from master outs to the newly installed noise monitors for ITMX.  I started but didn't finish making the same set of measurements for ITMY.
