DAQ restart, new dust monitors and safety channel renaming

Jeff B, Patrick, Dave:

14:06 PDT: DAQ restart primarily to add LVEA dust monitors 3,4,5,30 to the frame (a new H1EDCU_DUST.ini). We also installed a new H0EDCU_SAFETY.ini in which channels named IOT2R were renamed SQZT6.

h1nds1 did not restart cleanly, monit reported it was not being monitored. I manually restarted it via monit.

I renamed the second trend files which contained the DAQ restart  (H-H1_T-1189890000-600.gwf) so that second trends which span this time do not return invalid data.

OpLev at EY failed at Recent Power Glitch

It was just discovered and brought to my attention that this Oplev failed to recover after the glitch.

Today's in-chamber vent report

This morning, the door crew was at it early and had the doors off of HAM2 (E and W) by 9:30am.  Hugh and Jeff B started the entry contamination control, Hugh locked the ISI, and I locked the 4 large SUS (PRM, PR3, MC1, MC3) in order to put the face caps on for protection over the first few days of ISI work.  (The optics are the only masses locked, and somewhat lightly in order to just support the addition of the caps on.)  WHile there, Hugh and I also removed the 2 MC free-standing arc baffles which are going to be replaced, and the OPLEV 2" mirror/mount which is going to be replaced.

Hugh started the HAM2 ISI damper work mid morning, which is expected to run the next couple of days with Jim.

Since they were all geared up and ahead of schedule, Bubba and crew went ahead and pulled the BSC3 W door in the biergarten.

 

I also unplugged the power supply adapter box for HAM3 Optical Lever Transceiver to get an open power port to power the B&K setup.

For pictures of today's work, check out 38716.
I attach the two money shots I got here though, 'cause they're great.

For future reference, it's Betsy and Hugh in garb.

h1brsey computer power cycled

Jim and Dave:

as part of EY BRS code issues, I power cycled the h1brsey computer. This was a full power down, using the rocker switch on the rear of the unit after the windows operating system had shut the machine down.

replaced broken DC power connector on EY IRIG-B fanout unit

Fil and Dave:

We replaced the 12V DC power connector on the EY IRIG-B unit. The original connector had a bent locking screw which made powering the unit down difficult. The new connector has a thumb screw and does not need a screwdriver to disconnect.

All the models at EY were stopped for the duration of the repair, and restarted at 11:20 PDT. The front end computers were not power cycled.

An improved design would have an ON/OFF breaker on those units.

WHAM3 H2 CPS Noisy again but only after recovery from Power Glitch

The attached plot shows 10 days of the HAM2 Corner2 Horizontal CPS.  There is about 24 hours of low noise condition after I power cycled the CPS section of the Interface Chassis.  The Saturday power glitch is obvious as is the noise level after front end recovery.  I'll do the power cycle again but it is weird to power cycle to correct a problem originating from by a power cycle.

corner station vented

SLOOW vent accomplished. HAM 1 took about 8 hrs, HAM 6 about 7 hrs, and vertex about 9.5 hrs.

All piranis need to be calibrated at atmospheric pressure; they were all over the place. PT180 flat lined at 750 Torr. PT120 drifted to 1150 Torr (known issue and will be replaced). The third gauge on vertex, PT170, plateaued at 607 Torr. PT100 on HAM1 plateaued at 753 Torr, and PT110 on HAM6 at 620 Torr. Note that PT110, 170, 180 are the new style full range gauges:  pirani+hot cathode all-in-one.

Closed all three purge air valves to chambers/volumes.

GV5 AIP high pressure

GV5's annulus ion pump went out of range during the vent today. Known inner o-ring leak somewhere not on beam tube side. Turned AIP controller OFF and also valved out the pump.

H1EDCU_DUST.ini modified to add new dust monitors, will go in on next DAQ restart

Jeff B, Dave B,

I have modified H1EDCU_DUST.ini to add the four new LVEA dust monitors (numbers 3,4,5,30). This will go in on the next DAQ restart.

HEPI Pump Pressure 45 Day Trends

See attached screenshot.  Things I noted were:

• There is a glitch in both the EX and EY pump pressure on August 22 which likely corresponds to a HEPI trip described in alog 38313. 
• There is a large spike starting around August 12 that trends back to ~nominal which is likely due to HEPI being locked (aLog 38618).  The signal flatlines thereafter. Was the CS pump station turned off after all HEPIs were locked??  I failed to locate an aLog if this is the case.
• There is another glitch in both the EX and EY pump pressures Sept. 17, which is likely due to Hugh restarting the HEPI pump (?, no aLog yet although it was discussed in the morning meeting) after the Sept. 16 power outage (aLog 38675). 

PSL Weekly Report - 10 Day Trends FAMIS #6166

PSL is undergoing quite a bit of maintenance. Power down of the system is quite evident indicating the NPRO replacement and the ensuing power fluctuations during alignment. The Chiller manifold was also replaced and ensuing leaks were mitigated over the following few days.

Times switching from TX/RX PCAL channels for calibration

For the purpose of injecting PCAL lines, there are two channels that can be used: H1:CAL-PCALY_RX_PD_OUT_DQ (for reflected light) and H1:CAL-PCALY_TX_PD_OUT_DQ (for transmitted light). At various points during O2, we switched off between these two channels in C00 and C01 data at Livingston to account for things like PCAL clipping in the RX channel. The exact dates of each change are listed below, as documented on the filter configurations wiki page.

Version C00
Used RX from 116440990 (2016 Sep 14, 16:43:07 UTC) -- 1182618646 (2017 Jun 27, 17:10:28 UTC)
Used TX from 1182618646 (2017 Jun 27, 17:10:28 UTC) -- now

Version C01
Used RX from 1163173888 (2016 Nov 14, 15:51:11 UTC) -- 1181941760 (2017 Jun 19, 21:09:02 UTC)
Used TX from 1181941760 (2017 Jun 19, 21:09:02 UTC) -- now

The corresponding record over at Livingston is in aLOG 35948.

CDS computing recovery from Sat power glitch continues

EX timing was reporting error with 4th Duotone slave, and h1iopiscex was in error. I found that the timing slave on h1iscex's IO Chassis was still trying to sync up (flashing LED). This system has a separate DC power supply for the timing slave, part of a past noise study. I power cycled both the timing slave and the IO Chassis, and now the code is running correctly and the timing error has been resolved.
