ODC medm screens for HPI
I updated the HPI ODC channel screens to include the bit description read-backs. I also added a bit-bar to the overview screen.

While doing this I noticed that the sitemap sets different userapps variables for HPI HAM1 vs the remaining HAMs. Look at the userapps directory name.

HAM1: SITE=LHO,site=lho,ifo=h1,IFO=H1,chamber=ham2,CHAMBER=HAM2,IOP=SEIH23,iop=seih23,DCUID=54,IOPDCUID=53,IOP_NAME=SEI_H23,USERAPPSDIR=/opt/rtcds/userapps/release
HAM2: SITE=LHO,site=lho,IFO=H1,ifo=h1,CHAMBER=HAM1,chamber=ham1,IOP=SEIH16,iop=seih16,DCU_ID=49,IOP_DCU_ID=48,IOP_NAME=SEI_H16,USERAPPS_DIR=/opt/rtcds/userapps/release

The Sitemap was updated so HAM1-HEPI would be consistant with HAM2-HEPI.

ODC medm screens added to all sus screens (except HAUX)
I added ODC channel screens, including bit label readbacks, to all SUS overview screens. The only suspensions that still don't have ODC bits are the HAUX (Ham auxiliary).

PR3 alignment is well underway

Jason and Travis set the IAS PLX in the HAM3 South spool.  After coarsely adjusting yaw and pitch of the reflected beam back into the PLX, we are now fine tuning those DOFs via the pushers and the pitch masses.

PS - Arnaud checked spectra at lunch to make sure PR3 and PRM were not rubbing for the IAS pointing measurements.  Will check again before we're finished.

betsy.weaver@LIGO.ORG - 16:01, Thursday 14 March 2013 (5800)

PPS - we also vacuumed the HAM2 East side of the table/components, and then pulled the PR3 and PRM FirstContact in order to start the IAS alignment.

MC3 Top Mass Blade EQ stops switched for shorter

Today, with the approval of the resident IO rep Chris, I swapped in the MC3 top mass blade tip EQ stops (a necessary retrofit with an ECR (has a number, yada yada).  To date, the MC1 and MC2 still need them.  Other HSTSes have the correct screw.  These are on the to-do list for next week.

DC Power Supply Installed & Internal Cable Tray Moved On IOT2L

Kiwamu had a DC Power Supply box (D1002932) he wanted installed inside the IOT2L.  After ordering a few parts, I went about installing the box; this required installing support brackets.  These support brackets required moving the entire internal cable tray a few inches toward the doors (which isn't trivial with all the cables cable-tied down).  After a bit of grief and sweat, the box is installed and ready to go. 

Pictures for IOT2L are in ResourceSpace here.

ODC MEDM screens for BSCISI and SUS QUAD
Ryan Fisher, Jeff Kissel, Stefan Ballmer

We started added the epics bit label strings to the ODC medm screen. Ultimately these strings are intended to be initialized my the front end model to keep track of long-term ODC bit assignment changes. For now we populated them by hand (see Ryan's elog).

So far we modified the medm screens for the BSCISI (BSCISI/ISI_CUST_CHAMBER_ODC.adl) and added the SUS quads (SUS_CUST_QUAD_ODC.adl). For the quads we modified the OVERVIEW screen to include a button to the ODC screen, and reduced the number of ODC bit indicators to the bits 0 to 12 that are currently used.

Many more screens need to be done: SUS triples and auxiliaries, HAMISI and HEPI.

Setting ODC EPICS Descriptive Bit Strings
Ryan Fisher, Stefan Ballmer

We have set the EPICS records for the labels that describe the ODC bits for the SUS and ISI models currently running in H1.*  The labels provide a short description of what every bit in each ODC channel represents, for each ODC channel.  The higher order bits in the ODC channels that do not have labels are currently unused, but may be used in the future.

These records were set using scripts located in /ligo/home/ryan.fisher, and attached to this entry.  

* Excluding H1:SUS-TMSY_ODC_BIT* for now.

I have now also set all of the EPICS strings that describe the bits in the ODC channels for the HPI models.  The script is attached.

I have now also set all of the EPICS strings that describe the bits in the ODC channels for the TMSY model.  The script is attached.

Note that there is a small bug in the models for these channels that currently mislabels bit4 as bit6: 
H1:SUS-TMSY_ODC_BIT6
(should be H1:SUS-TMSY_ODC_BIT4)

We will go through the process of changing this small bug in the corresponding Simulink model library part, after emailing cds_announce and sus team members.

I added scripts for setting the ODC bit labels and masks in /opt/rtcds/userapps/release/cds/h1/scripts

h1setODCbitmask:    Set ODC bit masks for HPI, ISI and SUS

Correction to scripts included above: 

The ISI-HAM ODC channels should only have 5 bits, and should not be part of the other ISI channel script.  The corrected scripts are attached, and the correct scripts are in the following location on llocds.ligo-wa.caltech.edu:

/ligo/home/ryan.fisher/EPICS_Scripts

I corrected a small typo (M2 where it should have been M1) in SUS_OMC_Labels.txt for this log book entry only.  The scripts in /ligo/home/ryan.fisher were corrected approximately a month ago.  The corrected txt file is attached.

plots of dust counts
Attached are plots of dust counts > .3 microns and > .5 microns in particles per cubic foot requested from March 13 00:00 UTC to March 14 00:00 UTC. Also attached are plots of the modes to show when they were running/acquiring data.

Data was taken from h1nds1.
T0=13-03-13-00-00-00; Length=86400 (s)
1440.0 minutes of trend displayed

'No data output' error on > .3 micron plots.

I forgot that the dust monitor at end X had been removed from the edcu, so the data has not been saved since I turned it back on this morning.

Input Optics Work
[Deepak K., Rodica M., Chris M.]

Tasks Accomplished:
* Realigned MC Refl beam through the periscopes.  It was off center on some of the baffles by 1/2 a beam diameter.
* Tweaked the alignment of the beam through the Faraday. It was reasonably well aligned already, but we made a small adjustment to IM1.
* Implemented Rodica's brilliant idea to reroute the MC Refl beam to overlap with the main beam.  We did so by using two eLIGO steering mirrors and injecting at MC3 (see pictures).  This gives us the full ~180 mW of power downstream of the IMC to align auxiliary beams.
* Installed the HWP in the rerouted MC Refl beam to correct the funky polarization.

Notes:
* The first hard aperture(HA1) needs to be recentered after the clamp issue is fixed.  (It has a large dog clamp).
* The AOEs are missing their second SiC baffles still.  Recheck the centering after the baffle is installed.  
* We removed MC3 AR Baffle and placed it in front of MC3.
* We borrowed the HWP from the main beam line to correct the polarization of the rerouted MC Refl beam.

Power Recycling Cavity Alignment Summary
A summary of the current state of the PR cavity optics alignment.  Due to the small yaw angle of each optic the directions listed in parentheses with each lateral and longitudinal position error are only approximate and should only be used as a guide to roughly visualize the direction of the error.
 
PR2
 
PR2 alignment has been completed, the positional/angular errors are:
PR3
 
PR3 positional alignment is complete.  Since the setup for PR3 and PRM positional alignments are almost identical we decided to align PRM position before doing PR3 pitch/yaw.  PR3 positional errors are:
PRM
 
An initial look at PRM position alignment was taken today; longitudinal and lateral position only.  The errors are currently:

Tomorrow we will measure the PRM vertical position error, make any shifts of the PRM that are required, and then move on to PR3 pitch/yaw alignment.
