The morning meeting days will change to 08:30 on Monday, Wednesday, and Friday. Monday's meeting will address review of weekend activities and work permits for Tuesday's maintenance. The Wednesday's will be a planning session. The Friday meeting will focus on FRS topics and weekend work.
  
   There is grouting still going on in the HAM2 area and at End-Y. Should be finished today.

   Vacuum is still pumping down in LVEA. Will be on Turbo pumps and annulus pumping for several days to weeks.
   
   Higher power operation of the PSL is planned for the week 04/04. 

   Tuesday Maintenance:
Reboot End-X vacuum computers for Beckhoff. 
POPX and WFS
BRS at End-Y
PI Boot   

Attached are 45 day trends of the various PSL power monitors.

The degradation of the power matches the decline of the front
end laser pump diodes.

Transition Summary:

Title:  03/21/2016, Day Shift 15:00 – 23:00 (08:00 – 16:00) All times in UTC (PT)
State of H1: IFO unlocked. Planned Engineering
Commissioning: 
Outgoing Operator: N/A
 
   Environmental conditions are favorable for relocking. Will see what the plans for the day are at the 08:30 meeting.  

After realigning the IFO, I lost lock a couple of times during ASC_PART1, due to PRC2_Y engaging.

Going slow the next time, it first looked like the IFO was more happy with the PRC2_Y input matrix of RF9I=0, RF45I=-1 .

But after about 15min the the input matrix from the guardian script - RF9I=0.7, RF45I=-1 , seemed to work just fine.

In the attached plot, notice that the RMS in all signals shrank significantly over about 15min.

So far so good. 

Hang, Stefan

We went through the whole initial alignment today. The hickups along the way were:

- Because the green cameras are off-line, we turned off the ITM green camera centering loops: all four  H1:ALS-[X|Y]_CAM_ITM_[PIT|YAW]_ERR OUTPUT OFF

- This meant that the best reference on the ITM was the baffle-pointing from the TMS - we found arm alignments that correspond to those TMS pointing positions.

- Input alingment and PRM alignment were simple.

- Next we had trouble locking both MICH_DARK and the SRY cavity - we tracked it down to large electronic offsets on the AS 45 diode. We set the dark offsets on all LSC and ASC RF photodiodes.

- Then ALS DIFF wouldn't lock. Also took a while to track it down to an ESD that was switched off.

- Next we tried to lock DRMI, but ALS got kicked during locking transients. We first suspected the BS OPLEVs, but they were fine. Turns out the SRCL FF was left on - so SCRL kicked the ITMs. We updated the down script to turn FF off.

- After all that the alignment had drifted enought than we needed to realign the corner, which then was enough to lock DRMI.

- Next DRMI always lost lock on ASC engaging. Turns out the input matrix element for MICH_P was not properly set up (two lines of code were commented out)

- With that we reached DRMI_LOCKED, and continued all the way to DARM_OFFSET.

- Finally ENGAGE_ASC_PART1 failed, due to a run away PR3 YAW loop.

That's there we left it for the day.

1/2 open LLCV bypass valve, and the exhaust bypass valve fully open.

Flow was noted after 1 minute and 10 seconds, closed LLCV valve, and 3 minutes later the exhaust bypass valve was closed.

Next over-fill on Monday, March 21st before 23:00 utc.

Activity Log: All Times in UTC (PT)

22:30 (15:30) Take over from Ed
22:51 (15:51) ITMX & ETMX ISI and SUS TMSX WDs tripped due to a mag 5.2 EQ near Vancouver Island, CA.
23:44 (16:44) Started working on initial alignment.

End of Shift Summary:

Title: 03/18/2016, Evening Shift 23:00 – 07:00 (16:00 – 00:00) All times in UTC (PT)
Support: N/A               
Incoming Operator: N/A

Shift Detail Summary:  Working with Stefan & Hang to relock the IFO. Had the TMS(s) realigned and the X-Arm green. While working on Y-Arm green, took a mag 6.2 EQ off Atka Alaska, which rang everything back up, tripping the ITMY ISI WD several times. Decided to call it a night and try again tomorrow.  

Hang, Jeff, Stefan

After all the grouting we had to do a rough manual arm alignment to see the transmitted beam.

After that we ran the baffle alignment script:

/opt/rtcds/userapps/release/asc/h1/scripts/ditherAlign.py

We also had to adjust H1:AOS-xxxx_BAFFLEPD_x_NOMINAL for thje script to catch the baffles (for some reason they were changed after O1).

That all went fine until the next double earthquake hit - Atka, Ak, Magtnitude 5.0 & 6.2. The attached alignment should at bleast let the green arms flash.

Lost power to the Y-End station Instrument air compressor.

Initial inspection revealed the circuit breaker had tripped.

Found main lead wires shorted against a stud.

Wires were replaced and power restored to Y-End station Instrument air compressor.

CP7 went into alarm due to the lack of air, but is now recuperating, it reached a low of 81.3% full, as of now is at 86.2% and green.

Late entry from Thursday, I installed the new Newtonian Noise model on h1oaf0, it is called h1ngn. At the same time Hugh and I restarted the BSC ISI models (except for itmy which had been done previously). We did a single DAQ restart to sync these changes.

The DAQ restarted with no problems, but later in the evening h1fw0 went unstable and restarted 7 times between 20:42 and 23:42 PDT and then became stable again.

GV 1,2,5,7 are now open. GV 5&7 opened with 40 psi air.

Gate annuli valves were opened and closed again. Values of the annulus IPs:

GV-1: 5 mA
GV-2: 7 mA
GV-5: 2 mA
GV-7: 2 mA

Turbo pumping stations' 10" valve closed on X & Y and shut down completely. IPs are open to spools.

Turbo on diagonal is backed by local scroll only. QDP80s are OFF. Kolbelco is OFF. Chilled water line is still open in mech. room for diagonal turbo pump.

Current pressures:

X: 2.6e-8 Torr
Y: 2.5e-8 Torr
Diag: 6.0e-6 Torr

WHAM6 completed this afternoon.  Note--Swapped out old Capacitive Position Regulator Board D1001474-v1 for a v3 model.  This was on the CPS2 Satellite Chassis.  The platform Isolated with no issue.

So now all the LHO CPSs are on the 71 MHz timing sync.  WP 5773, FRS 4554 aka II 1058, ECR E1500244, D1400363

After the weekend of quiet, I'll compare befores and afters.

John, Gerardo, Chandra

Opened the diagonal volume to the turbo pumping station at 10:00 local time (PDT) at 0.8 Torr. 

Current pressure is below pirani range but cold cathode won't turn on yet.

Gerardo, John, Chandra

Leak checked:

Full range gauge conflat on BSC7
Full range gauge conflat on BSC8
Two viewports on X spool
Two viewports on Y spool

No leaks found!

Background on X was 1.0e-9 Torr-l/s
Background on Y was <1e-11 Torr-l/s

Sprayed each flange with helium for 20 sec. 

Re WP 5774 FR 4694 (PKA II 1193)

To offload the ISI witness point motion calculation from the SUS to the ISI which runs slower and has more computation headroom.  See 25913 for original update to ISIs--the SUSPOINT being the important thing.  Looked at comparing the calibration of the ISI motion in the SUS 16k machine vs the 4k ISI machine in LHO aLog 25993--Jeff & I may look more closely at this but we think all the differences are explainable.   The original updated library parts were modified to capture the data in frames--see 26128.  After restarting the ITMY model to test these changes and adapting the implementation for ISIs which have multiple suspensions (See Attached) earlier this week, yesterday, 17 March, the remainder of the BSC ISI were restarted.  All restarted fine--26117.

This morning, the Calibration filters have been loaded and following JK's aLog 4553, I've populated all the new BSC ISI CARTESIAN to EULER matrices.

I believe this means that DetChar can repoint the detchar plots from the SUS model to the ISI models.  Once there and we are happy, the SUS calcs can be removed.

The new channels are H1:ISI-{isi}_SUSPOINT_{sus}_EUL_{euler dof}MON where

isi = ITMY BS ITMX ETMX ETMY

sus = ITMY BS ITMX ETMX ETMY TMSX TMSY  [The TMS projection matrices are identical to the ETM's so there is no new info there at the moment.]

euler dof = L T V R P V

Ah ha!  I see that the TMS matrices on the SUS do have values distinct from the ETMs.   I will update the database

/opt/rtcds/userapps/release/isc/common/projections/ISI2SUS_projection_file.mat

to include the TMSs and correct the ISI CART2EUL TMS values shortly.

h1conlog1-master has still not connected to 1736 channels since the maintenance work yesterday (alog 26112). I checked the unmonitored channel list and with the exception of two, they are all of the channels that are not read-only in /opt/rtcds/lho/h1/target/h1ecatc1/h1ecatc1plc1epics/autoBurt.req, that is h1ecatc1 PLC1. The two other channels are H1:PEM-CS_DUST_LAB1_ENABLE and H1:PEM-CS_DUST_LAB2_ENABLE, which I confirmed do not respond to a caget. I can do a caget from h1conlog1-master on the couple of unmonitored channels on h1ecatc1 PLC1 that I tried. It is also worth noting that conlog-test-master has the same issue with the same channels. I tried restarting conlog-test-master and it still does not connect to these channels.
