01:10 (17:10) Out of Observing 01:21 (17:21) Back into Observing Took IFO to Commissioning to adjust recycling power. Moved TMS-Y pitch from 138.4 to 136.2 and yaw from 21.4 to 21.3. POP_A_LF_OUT is now between 16160 and 16200 counts. Will monitor for continued drift and adjust as necessary.
FRS 4177, Bugzilla 960 The wmctrl package has been installed on most Ubuntu control room workstations. The workstations that have NOT had wmctrl installed are opsws6, opsws9, and operator0.
Kyle, John After first decoupling the 3/8" tubing at the top of the CP3 vacuum vessel, we fed SS wire into the obstructed 1/4" level sensing tube. We were able to feed enough wire as to think that we were within 1 foot of where the tube connects with the inner LN2 reservoir -> We then remove the wire and coupled the 3/8" line For tonight, we are leaving the two sensing lines combined at the 3-valve valve body via opening the valve which normally isolates the two.
Transition Summary:
Title: 01/11/2016, Evening Shift 00:00 – 08:00 (16:00 – 00:00) All times in UTC (PT)
State of H1: IFO locked and in Observing. Calibration work continues. The POP_A_LF signal is still drifting lower. The plan is to tweak TMS alignment as soon as current hardware injections are complete.
Outgoing Operator: Ed
TITLE: Jan 11 DAY (half) Shift 20:00-00:00UTC (12:00-16:00 PDT), all times posted in UTC
STATE Of H1: Observing
INCOMING OPERATOR: Jeff B
QUICK SUMMARY:
Ground motion is high but not too high from preventing stable locking
IFO locked in the 78Mpc range for past 3 hrs
Downward trend in recycle power will need to be addressed at the end of calibration testing at LLO
Shipment of Transformers arrived. Truck diverted to LSB where Bubba met for the offload
ACTIVITY LOG:
11:20 IFO re-locked at NLN
11:21 Intent Bit set to Observing
22:02 Truck Loaded with transformers for Bubba
22:03 Intention Bit momentarily toggled for changing of ETMY calibration lines
22:46 Kyle and John out to MY to do daily CP3 overfill
23:21 Watching recycle power decay. LLO is running calibrations. We have ≈1.5 hours until we need to re-align TMS to correct in order to save lock. This is about the same amount of time that Chris Biwer will need to complete his work at LLO
Shift Summary: Was Observing unitl an earthquake in Philippines knocked us out.
Incoming operator: Ed
Activity log:
17:03 Lockloss due to an earthquake. See alog24858.
17:12 Rick shutdown 5 kHz Pcal line at X-end.
18:59 Bubba going to mid-Y to work on the pipe under the beam tube.
20:00 Hand over the ifo to Ed.
Monday Morning Meeting Notes
- Jeff gave update on the calibraiton world (sorry I didn't really catch the content. I heard something about high frequency line and data quality flag). Tomorrow is the end of calibration period.
- PEM injection period after O1 ends.
- After tomorrow -- don't call people at night (except for Mike and Richard).
- IFO should be ready to be handed over to the comissioners by Friday.
The temporary PUM and UIM calibration lines slipped passed Rick when he was turning off the last of temporarty calibrations fromt last night. We noticed only after Chris had begun his first injection, so we waited for enough data then briefly went out of observe and turned off the lines -- out of observe at 22:01:27 and back in at 22:02:23 UTC.
FRS 4201 The OMC trans camera (h1cam20) software needed to be manually killed and restarted. Monit would not restart until the pid file had been deleted. Also restarted h1cam14 and h1cam17 since they were in the same state.
11:21UTC @ 76Mpc - Sidenote: I had to manually tweak TMSY to maximize Recycling Power.
I will be conducting some hardware injection tests at H1 and L1. This aLog will be updated as hardware injections are scheduled.
I am adding the following to the schedule file: 1136584223 1 1.0 coherentbbh20_1135136337_
We will leave observation mode briefly and Jeff will turn off two PCAL lines that were on from the PCAL tests. Hardware injections will resume afterwards.
We are back in observation mode, the PCAL lines are off and I've added the following lines to the schedule: 1136586132 1 1.0 coherentbbh21_1135136336_ 1136587232 1 1.0 coherentbbh22_1135136336_ 1136588332 1 1.0 coherentbbh23_1135136337_ 1136589432 1 1.0 coherentbbh24_1135136337_ 1136590532 1 1.0 coherentbbh25_1135136337_ 1136591632 1 1.0 coherentbbh26_1135136336_ 1136592732 1 1.0 coherentbbh27_1135136336_ 1136593832 1 1.0 coherentbbh28_1135136335_ 1136594932 1 1.0 coherentbbh29_1135136336_
These injections are now complete.
My first attempt to examine my alignment resulted in a perfect transition from PRMI to DRMI. It seems talking about it causes it! She's a very sensitive IFO.
TITLE: Jan 11 DAY Shift 20:00-00:00UTC (12:00-16:00 PDT), all times posted in UTC
STATE Of H1: Locking
OUTGOING OPERATOR: Nutsinee
QUICK SUMMARY: IFO locking. EQ bands have rung down but still not exactly nominal. The "mean" µSei seems to be right above the 90%ile with the Z-axis peaking up to 1µm/s. Winds are calm. Thank you Nutsinee for covering the morning!
EvanG, Travis, Darkhan,
Today we repeated Pcal end-station measurements at EX, the procedure is described in T1500063. Rough readings from dataviewer and GPS times are given in the attached notes.
The outer beam still show a significan drop in power between Transmitter and Receiver modules, earlier we thought that the beam was not well centered at the input port of the RxPD integrating sphere, but by looking at an outer beam spot with IR viewing card it does not look to be the case (see attached picture).
Earlier this week we took a similar set of measurements, but we suspected that WS/TX when WS is inside of received module were not taken properly and today's measurements were taken as a double-check (LHO alog 24726).
We will post a full report and some conclusions soon.
A generated report (comparison with previous measurements) was uploaded to DCC T1500129-v4.
This report gives us more confidence that our measurements taken on 2016-01-05 (LHO alog 24726) were not made properly, because
on 2016-01-05 the value of RX/WS (not optical efficiency corrected one) changed by ~ 2 %, but
on 2016-01-08 this ratio was back to it's value measured earlier in O1.
The data point for 2016-01-15 will need to be removed from future end-station measurement reports.
During Pcal end-station TxPD and RxPD measurements the ETM must be aligned.
This conlog is made to confirm that ETMX was aligned during measurement process.
Performed a run spanning the time period from 1132963217 (Dec 01 2015 00:00:00 UTC) to 1136155727 (Jan 06 2016 22:48:30 UTC)
The following parameters were used for this run:
During this time period, 12 scheduled injections were found to have occurred
Only 1 injection was found to not occur:
Of the occurring scheduled injections, only two occurred as single-IFO injections:
All other scheduled injections occurred as H1-L1 coincident injections. The only UNSCHEDULED injections were 5 CALRESETs at L1 and 1 CALRESET at H1.
The CALRESET injections have the same pattern of occurring with only certain paired combinations of the frame flags indicated by HWInjReport, as seen previously. However, all of the occurring scheduled injections have the anomaly of not occurring in the CAL-INJ channel and not having the TRANSIENT bit set to “off” to indicate the presence of a transient injection. They do occur, consistently, in the ODC-MASTER channel for HOFT, RAW, and RDS frames and the GDS-CALIB channel for HOFT frames.
Minor correction made to report. There were, in fact, 2 single-IFO injections that occurred, both in L1. I missed the second one due to an eyeball error.
As reported by Chris B. in https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=24282, the two single-IFO injections were the result of H1 losing lock.
The absence of occurrence of the injections in the CAL-INJ channel turns out to not be an anomaly but the result of a deliberate change to using the new CAL-PINJX_ODC_CHANNEL_OUT_DQ channel to record the information that was originally in CAL-INJ_ODC_CHANNEL_OUT_DQ. Currently, HWInjReport does not check the CAL-PINJX channel, however, it should not be difficult to add checking on this channel.
