Apollo got the doors off HAM2 and I followed with locking the ISI--no difficulties.
I took a few photos, mainly focused on the cabling coming off Stage0 to the electrical feedthrus.  Lot's of work to do in this department; the NW corner is pretty good but the others, not so much.  The last image is from the East (right) side and shows the PR mirror's dummy masses that will need to be removed.

Minor administrative changes to hpi pump controller h1hpipumpctrll0, configured resolv.conf to allow other computers on network to be found by name, and started the ntp daemon to keep the time up to date.  Time was reset to current time (it was off by a few minutes).

There were no unacknowledged alarms ringing this morning.  Channels that were in alarm status were the following:

• H!SUSB123-SUS-ITMY-CPU-MAX (yellow)
• H!SUSB6-SUS-ETMY-CPU-MAX (yellow)
• H1:IOP-SUS_B123_ITMY_WD_OSEM5_LPOUT (yellow)
• H1:IOP-SUS_B123_ITMY_WD_OSEM6_RMSOUT (yellow)
• H1:PSL-OSC_XCHILALARM (red)

After a restart of the alarm handler, the two CPU-MAX alarms and the two IOP-SUS_B123 alarms returned (yellow).

As part of WP3715 I added a DAC output part to h1pemmx and restarted the model. This removed the "DAC not in use" flag but added in the "18bit DAC does not have an AI chassis connected" flag. Since the DAQ status went to 0x2000 (ini file change) I reverted the model back to the original for now rather than restart the DAQ. We will install the AI chassis for the PEM to green-up these systems.

Not a show stopper, but darn unfortunate for a variety of reasons.  After installing the glass PR3, I noted that you cannot easily adjust the middle mass AOSEM  positions.  After a call to LLO to confer, I discovered that they reworked the brackets just before installation of their PR3!  Fortunately they made 1 set extra, so it was overnighted our way.  The unfortunate part is that I need to remove 8 silver plated screws from the awkward position on the inside of the cage over the optic, rework the bracket assemblies, and then reinstall them.  The attached picture shows the "old" brackets - a circle indicates the captured adjutment screw.

Go the Last two Corners Leveled today with help from Mitchell and Ed.  I'll report tomorrow on position changes.  HAM1 HEPI has now been relocked.  I also spent a lot of time securing the electronics cabling.  After one round of cleaning and bolt loosening, I found several of the L4C cables unplugged.  They had not been secured, my fault, so I dressed and secured them much better than they had been.

Attached PR2 and MC2 power spectra for a safety check. Ran after some installation work on HAM2, where the ISI table have been incidentally moved and the optics might have touched the earthquake stops. 

Richard fixed a short on the HEPI pump controller.
The fire department was testing smoke detectors in the OSB and at end X. Dust counts in the optics labs were elevated as a result of tests in these rooms.
Hugh worked on HEPI L4C leveling at HAM1.
Dale took a group of college students from WSU on a tour, including into the LVEA.
Apollo removed the rigid section of spool BE-3A. Hugo took pictures of HAM3 from the north side.
Michael R. tested turning of an AC unit in the H1 PSL enclosure.
Greg worked at HAM5.

I did a quick temperature test of the PSL room today, shutting off one AC unit (ACN) and seeing if the other unit could hold the temperature of the room steady. It could not. I turned the other unit back on after about an hour and the room temperature as returned to normal. The spike in the attached plot shows the temperature excursion.

We removed the rigid section of spool BE-3A and placed hard covers on each end and placed on pallets. We laid both of these sections down for safe storage. Hard covers were placed on the flanges of bsc 2 and ham 3 as well. We loosened all of the door bolts on ham 2 after a 1st cleaning and plan on removing those doors tomorrow.

We pulled the soft cover off the North side of HAM3, and took a series of pictues in the chamber. 

These pictures will be used to asses the state of the ISI payload when we measured the ISI transfer functions for the Viton Pads Efficiency Investigation.

Attached phase 2b power spectra for PR3.
The two first pdfs show a comparison of the power spectra between L1-PR3 (June 2012),X1-PR3 (June 2012) and H1-PR3 (Feb 2013) respectively damping off and damping on.
The three others show the effect of damping for the top, middle and lower masses of PR3

New power spectra will be taken tomorrow since Betsy has to change some of the OSEMs.

Betsy wanted to set the M2 OSEMs on the beamsplitter so we logged the open light voltages and calculated the gains and offsets.

The Mid-Y entry bay is now full up with TCS optical enclosure equipment. Thanks to Rodney and Ski for helping me get it all moved in. 

Betsy and Deepak put the PRM and PR3 M2 and M3 OSEMs into the OL condition and I logged them. The values with corresponding gains and offsets are as follows:

Deepak and Bubba report they're done for the day, so commencing Matlab TFs on PR3.
