Mode 26 fixed

MODE 26 has been fixed: it has been raised due to an incorrect high pass placement implemented 2/10 when we were setting up new filters. I've fixed this and it should go back to normal amplitudes and damping gain needs. Thanks operators for alerting medealing with this.

(TRY QPD INP FILT #1 had accidentally been switched from a 14.8-15.8 kHz BP filter to a 32kHz high pass. I've reverted this. OMC DCPD INP FILT #3 still has its correct 31kHz high pass.)

Three vacuum gauges mysteriously turned off at EX

And now three cold cathode gauges turned off at EX:  PT523, PT524, PT510. I enabled the pirani interlocks and two came back instantly. Dave B. is going out to investigate. Robert is working at EX.

Pirani pressure plots attached.

Fire dept was out there too testing fire alarms. Should not affect vacuum rack but maybe a build up of static electricity??

GDS calibration pipeline restarted with gstlal-calibration-1.1.4-2
The primary and redundant pipelines were restarted at GPS second 1171131438. This restart picked up the new package gstlal-calibration-1.1.4-2. See https://bugs.ligo.org/redmine/issues/5115 for details on the associated changes. The CPU usage has is reduced from ~80% to ~ 55%. The latency is unchanged, as expected, and the output looks normal.

The filters have not changed. For information on the filters currently in use, see

QUAD Reset All Button / Script Converted to Python
J. Kissel, T. Shaffer, D. Barker
WP #6484
FRS #4231

TJ and I have re-written the problematic PERL script,
    /opt/rtcds/userapps/release/sus/common/scripts/wdreset_all.pl
in python, and saved it to the same location, just with a .py extension,
    /opt/rtcds/userapps/release/sus/common/scripts/wdreset_all.py

In order to test the new script, we've also modified the QUAD's watchdog screen,
    /opt/rtcds/userapps/release/sus/common/medm/quad/SUS_CUST_QUAD_WD.adl
and confirmed that the script works
    - on Debian *and* Ubuntu machines
    - for several different optics (we used ETMX and ETMY).

Both of the above new script and screen modification have been committed to the userapps repo.

We will write an ECR to change this permanently for all SUS.

I attach the new version of the python code. This replaces the perl code (quoted below, because not even the aLOG supports uploading .pl files!):
    #!/usr/bin/perl -I /ligo/cdscfg

    use strict; use warnings;
    use stdenv;
    INIT_ENV($ENV{IFO});
    use lib $ENV{USERAPPS_DIR} . '/guardian';
    use CaTools;

    # This script attempts to reset the watchdog, then the DACKILL.
    # If successful, returns with 0 status.
    # If fails, tries to print a reason, exits with status 1.
    # Accepts 1 argument: the subsystem name

    # Usage: ./wdreset_all H1:SUS-ETMX

    my $SubSys = uc(shift);

    caPut("${SubSys}_WD_RESET", 1);
    sleep(1);
    caPut("${SubSys}_DACKILL_RESET", 1);

Also, ECR has been filed: E1700056

PT310a interlock disabled

PT310b cold cathode gauge when out this morning. Found the pirani interlock disabled. Pirani pressure trend shows a spike in pressure. No known Beckhoff activity at MX this morning.

We saw PT245b go out last week. Minute trend shows no spike in pressure.

Confirmation of SUS Watchdog Reset Problems on Debian Machines
J. Kissel, D. Barker

This morning I was able to confirm what had given Corey trouble on Sunday night regarding the inability to reset SUS watchdogs on the new Debian work stations (see LHO aLOG 34084). The problem arises from a bug that has continually been re-identified over the past years (see FRS Ticket 4231, LHO aLOG 24950, LLO aLOG 24156, FRS ticket 4180 etc.): the "reset all" button is actually a PERL script, 
     /opt/rtcds/userapps/release/sus/common/scripts/wdreset_all.pl
which calls a depricated PERL module / library, 
     /opt/rtcds/userapps/release/guardian/CaTools.pm

I will work with TJ and Dave today to create a python version of the two-line script and update the MEDM call.

Jitter measurements

Here are some old measurements of the jitter coupling I measured by exciting the IMC PZT and measuring noise in DARM and IM4 trans.  

While T0900142 doesn't directly have transfer functions to compare these measurements to, but Kiwamu has been working on simulations that we can use directly.  Based on the strain given at the top of page 2 of T0900142, including a factor of 10 safety, the requirement is that the jitter signal should be less than 1.2e-21 m/rtHz at 100 Hz.  These measurements show a coupling of around 5e-13 m/fractional amplitude at IM4. If we used these measurements to make a requirement, it would be about 2e-9 fractional amplitude in the 01 or 10 mode at IM4 per rt Hz at 100 Hz, or about 50 times more stringent than the requirement shown in figure 1 of T0900142.  It looks like the couplings in the requirements document are either flat above 100 Hz or decreasing, where our measured coupling continues to increase as f at higher frequencies. 

Based on the accousitc injections in Anamaria's log, the LLO coupling at 100 Hz is similarly worse than what is calculated in the requirements document.
