Modification to external piping recently completed by Apollo -> Entire annulus volume (including gate annulus) had been vented to facilitate this mod -> Gate annulus volume is temporarily combined with rest of annulus volume being pumped by aux. cart -> 1.5" all-metal isolation angle valve to be closed after a few days to re-isolate gate annulus volume (i.e. restore nominal configuration).

The concrete floor at the spool was covered with CPStat after the PEM fence was removed. The CPB jigs were moved to the far side of the beam tube by Apollo and then the tech cleaners removed Sharpie and other egregious "stuff" from them.The ISI storage container top was removed from the VEA and taken to X-Mid. The E-module and spiral staircase were moved down to the end and then the E Module was moved into the VEA. 

A small piece of vinyl was torn up by the big pallet jack used for the ISI. Since the tear is in the Test Stand area, John is contacting the vendor to get a repair taken care of before the ISI is in place.

Morning Alarms:
- CDS all are CPU Max and IOP watchdogs - no action necessary 
- Dust alarms are all due to working people - no action necessary

Morning work:
- forklift work near test stands in LVEA

Currently:
- Filiberto in LVEA fixing cables on the CM servo board.

Reboot EY Ethercat System

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.

9.	Move E-module and Spiral Staircase into VEA (Apollo)
10.	Remove door from BSC9 for PCal install (Apollo)-Put hard cover in place until door is needed by PCal?
11.	Place lower Garbing/Staging CR (Apollo)
12.	Assemble and place E-module including upper garbing/staging cleanroom (Apollo)
13.	Place Test Stand (Apollo/IAS)
14.	Clean Test Stand and cleanrooms: CPB, Test Stand, Work Space and lower G/S (Tech Cleaners)
15.	Fly ISI to Test Stand (SEI/Apollo)
16.	Move Test Stand CR over ISI (Apollo)
17.	Get ISI Storage Pallet out of VEA (Apollo)

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.

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.
