Active control was left off to avoid perturbating the investigation of a large unexplained offset whitnessed on MC1.

I turned the active control back on this morning, on both HAM2 and HAM3 ISI to help locking the IMC, and assess performance. Active control is the same as it was for the IMC test:

• Damping loops
• Ryan DeRosa's Blend Filters
• ISOlation loops Level 2 (UGF ~25Hz)

Recent performance spectra can be found here.

On Monday, Andres and I removed the ETMx all-metal lower structure from the staging building test stand and boxed it in prep for a move to Ex for it's monolithic re-build.

The IMC WFS loop were successfully closed.

We left the the IMC locked with the WFS loops ON to see how they work overnight. Some details will be posted later.

Attached are plots of dust counts requested from 5 PM June 3 to 5 PM June 4.

Both the dust monitor at location 14 in the LVEA (H2 PSL enclosure) and the dust monitor at location 16 in the LVEA (H1 PSL anteroom) are indicating calibration failures.

Arm locking achieved! 

As of 18:00 local time, we're getting lock to 00 at a level of 10000 cts on H1: ALS-Y_REFL_B_LF_OUT, out of a maximum of about 22000 cts. This is about a 50% drop. 

We've touched up the pitch and yaw to improve locking characteristics. The current positions in pitch/yaw are 

ETM: (-142.7, 197.0)

ITM: (247.5, -271.5)

The current gain on CMB-B input 1 is -18 dB. 

per WP 3937, GregG moved the HEPI Actuators on BSC2 to run mode.  We've been bleeding this chamber for 3 weeks, better not be much air left.  Tomorrow we'll think about releasing the locks and doing some commissioning.

We continue working away at the long list of items that need to be completed prior to PCal-CPB-ACB-ETMX install. Today, the ISI was moved from the Staging Building to X End VEA using a slow-moving Big Red. The CPB jigs were flown over the LVEA beamtube, loaded onto the trailer, transported to X End and placed in the VEA. See updated list below.

The h1pemmx models died 12:22:42 UTC June 2.  

At Mid X, found that portable power supply supplying the +24V to the I/O chassis had died, along with a mouse that was laying next to it.  Replaced the portable supply with a Sorenson from the EE Lab (given to us by Filiberto).

Power cycled the timing system hoping to get rid of the 1/2 second time difference that appears on the MEDM screens.  This did not have any visible effect on the timing, so we suspect we may have to wait until we get a known good pair of fibers for timing to the mid station identified before this is cleared up.

Powered up the I/O chassis and front-end computer, the h1pemmx model is now running.

Patrick T., Sheila D.

Since it was swapped in for troubleshooting, this chassis had been sitting on top of the corner station 2 chassis in the rack in the H1 electronics room. We added brackets to it and mounted it in the rack. There is now space below it for airflow for the corner station 2 chassis.

This work falls under permit 3936.

For all the dust monitors (except for the one in the H1 PSL diode room (h1dustdr) which was started yesterday with the latest code version) I moved the driver support code from met_one_227b-1.0.0 to met_one_227b-1.0.1 and the IOC code from dust_met_one_227b-1.0.2 to dust_met_one_227b-1.0.4.

There is no real change in the driver support code, just an update to the default EPICS base directory.
The IOC code also updates the default EPICS base directory and the path to the driver support code (to version 1.0.1). It also adds the IOC boot directory and database substitution files for the dust monitor in the H1 PSL diode room.

I restarted all of the dust monitors.

I created an autoBurt.req file for h1dustdr and added the channels to the alarm handler configuration file. I had already added a medm screen to the sitemap earlier. Jim B. added the channels to the DAQ.

A new tool called WD_Plots was created by SEI at Stanford (Charles, Brian and I). It allows plotting the timeseries for a given set of sensors/actuators at the time of the latest WD trip, by simply using a button on an ISI's Watchdog MEDM screen.

This tool was installed at LHO. Minor tweeks had to be made to stddir.py, which Jim Batch took care of. I tested it this morning (GPS time:1054403768) on HAM2-ISI.

To do so, I tripped the ISI, on the CPSs with a 20,000cts ramp on V1. Produced plots are attached (ACT, CPS, GS13). They were compared to data retreived with Dataviewer (ACT, CPS, GS13). Channel routing appears to be correct. So is lookup time.

I also picked a tripped BSC (H1:ISI-BS) and tried producing the plots from its WD screens. Time series could be displayed for each sensor/actuator set (1, 2).

WD_Plots works at LHO. It may now be used by the operators to diagnose when an ISI trips. 

I attached a pdf that shows how to use it from the ISI overview screens.

This is a first version that we are hoping to improve. Next, we plan on adding a vertical line to display the trip time on those plots.Further improvements could be done and operator feedback is welcome 

Note:
The scripts used are commont to all ISIs. They are under revision control at: 
opt/rtcds/userapps/release/isi/common/scripts/wd_plots/
The svn update performed on those scripts was covered by WP3903. Script were not changed since.

Attached are plots for the dust monitor placed in the cleaned 'dirty' clean room over the spool piece at end X. These are taken from 4 PM PDT May 31, 2013 to 7 AM PDT June 3, 2013.

According to the logbook at the door, no one entered the VEA at end X over the weekend.

I have made a configuration change in the core switch to allow DHCP requests to be forwarded between subnets; this is to allow us to use a single pair of DHCP servers for all of the CDS subnets.  Since we have been using (abusing?) the same configuration method to forward AWGTP discovery broadcasts to the Front End network, an ACL has been added to the OPS VLAN interface to filter out DHCP client requests from being forwarded to the FE network.  Server replies are not filtered as these need to propagate to the networks that request them.

Added H1ECATC1_PLC2.ini, H1ECATY1_PLC1.ini, H1ECATY1_PLC2.ini, H1ECATY1_PLC3.ini to master file, removed H1EDCU_ECATC1.ini.  Also edited H1EDCU_DUST.ini to include H1 diode room dust monitor channels.  Restarted data concentrator, but data concentrator could not parse the H1ECATC1_PLC2.ini file.  Error message "failed to locate first section in ...H1ECATC1_PLC2.ini"  

Edited the new H1ECAT* files, found "units=" missing actual units. Corrected, but the data concentrator still failed with the same error.  Changed slope from 1 to 1.0, removed ^M from the end of the lines, no change, data concentrator still failed.

Finally commented out the H1ECAT*.ini files to restart the data concentrator, as 20 minutes had passed.

Examined the H1ECATC1_PLC2.ini file with "od -c", found 2 unprintable characters at the beginning of the file (octal 377, 376) at the beginning of the file, and each "normal" character has a trailing 000 (byte of value 0) after...

0000000 377 376   [  000   d  000   e  000   f  000   a  000   u  000   l  000

Compare with a working .ini file:

0000000   [   d   e   f   a   u   l   t   ]  

The script that generated the H1ECAT*.ini files needs some repair.
