Took a look at the ETMx this morning to asses the alignment after the HEPI actuator install was completed.  As a reminder the large X axis positional error has been signed off by SYS, no correction will be performed.

• X axis Position: 3,999,485.0 mm
  • Target: 3,999,498.0 mm
  • Error: -13.0 mm
  • Tolerance: ±3.0 mm
• Y axis Position: -200.34 mm
  • Target: -200.0 mm
  • Error: -0.34 mm
  • Tolerance: ±1.0 mm
• Z axis Position: -79.8 mm
  • Target: -80.0 mm
  • Error: +0.02 mm
  • Tolerance: ±1.0 mm
• Pitch: -608 µrad (down)
  • Target: -360 µrad (down) -- [8 µrad ETMx pitch + 352 µrad FC correction]
  • Error: -248 µrad (down)
  • Tolerance: ±50 µrad
• Yaw: -30 µrad (CW)
  • Target: 0 µrad
  • Error: -30 µrad (CW)
  • Tolerance: ±50 µrad

IAS is now moving full time to the ITMx in WBSC3.  We will have to return to the ETMx to fine align the optic pitch and align the ETMx ACB.

This morning, I locked the BSC3 ISI and Greg went into the chamber and installed the corner cube. I'm not sure what state the ACB is normally in when the cube is attached, but it is in the lowered position right now, which made install of the cube precarious. Greg was able to do it, but it didn't look easy. Otherwise, we are ready for IAS to start working.

HAM's2 and 3 ISI's were locked this morning. Originally went out just for HAM2, but I saw that Apollo had just finished pulling the last door at HAM3, so I took advantage. I think immediate activities are planned only at HAM2, so if HAM3 needs to be released for some reason, let me know.

Because the DAQ was needed this morning for measurements, we didn't resurrect the dead h1sus56 computer until the afternoon. That meant I didn't get nearly as far as I'd hoped before leaving. My apologies. The current status is reported below, and will most likely remain as such until I get back from vacation on Tuesday.
 
Status:
- Mods to the HSTS_MASTER and HLTS_MASTER library parts (and all the library parts they use) are complete -- the HSTS required a little extra thinking, unfortunately
- The MC_MASTER remains unchanged, didn't get to it
- The top-level HLTS models' (H1SUSPR3, H1SUSSR3) mods are complete, and they compile successfully
- The newly compiled front end code for H1SUSSR3 has been installed, and is now running; PR3's has not yet been installed
- Of the HSTS', only H1SUSMC1's top level model has been completed and successfully compiled. The remaining HSTS models must be reconnected as h1susmc1's has in order to compile. They are guaranteed to fail compiliation for the time being.
- None of the necessary MEDM screen modifications have been made for the HLTS or HSTS.

Because I do not commit to the repository until I have a complete package for Stuart, the outstanding svn status I reported yesterday remains.

Transfer functions running on ETMX ISI, starting now. Should end by 8 AM. Running on opsws6.

The LVEA test stands (h1susquadtst, h1susbstst, h1seitst) have been powered off, removed from the DAQ, and removed from the dolphin configuration.  All equipment has been left in place for future use.

We got all the Actuators connected.  The last one, V3, took a while as we swapped out the suspect parker valve noted by Jim earlier.  The first one we swapped in L170 also appeared to do the same pull down Jim noted.  But this may have been a ringer.  We had not bled the actuator yet as we wanted to compare the performance and then we learned this valve had been removed from WHAM6.  However, we thought we were in trouble as the swap at WHAM6 was possibly unneeded because the problem there was that the Supply & Return hose were miss plumbed.  Still, we pulled L170 and swapped in L206 and bled the Actuator for 1.5+hours.  After we put the Actuator back in run mode, the Actuator drove back to a near center position so we deemed the valve problem addressed and attached this final Actuator.  Dial Indicators suggested we had tilted the table a few tenths, C2/4, so we followed with some tweeks of the big HEPI Springs to bring that back to start position.  Have alerted IAS/Jason that we are ready for a post Actuator look--he may be looking now.

On caveat here: since the ISI was floating we couldn't attach the corner cube to get an accurate longitudinal measurement.  The total station can use a "Sheet Refelctor" mode to measure the distance to the optic from the HR face directly, but this introduces more error in the measurement.  For the purpose of calculating the lateral and vertical errors a few mm of error in the longitudinal measurement means almost nothing at this distance (>33 m; a 5 mm shift in the longitudinal direction only imparts a change of <1 µm in the lateral/vertical error calculation), but I would not use this longitudinal measurement as a basis for the actual optic position (and adjust HEPI when it might not be necessary).  When the ISI is locked down we will attach the corner cube and get an accurate measurement of the longitudinal position error of the ITMx (and make any decisions about HEPI adjustments at that point).

These are still running the test code.

I changed the sample time to 20 seconds and the hold time to 280 seconds for the dust monitors in the optics lab, vacuum prep lab and bake oven room. These were set through the 'expert' medm screen for each.

I made PSL model changes this week to add channels to the science frame. Pre-empting next week's upgrade to matlab2012b, I modified all the mdl models used to build the code using 2012b (in some cases just adding an SVN $Id$ tag in order to make a change).

Today I tried to open the psl models using matlab2010a. I had no problems with h1psliss and h1pslfss, but h1pslpmc crashed 2010a. There are no problems opening this with 2012b. Presumably PMC uses some matlab parts with are not backwardly compatible with 2010a.

When I made the transition, the original 2010a versioned file was save by matlab with a 2010a prefix. We should always do this.

The Apollo crew and I started clean-up around HAM6 this morning. Randy and Eddy moved the squeezer table legs under the mezzanine stairs, which is an excellent long-term storage place for them. The pallets containing SEI masses and hardware were moved to less problematic spots. I located a rack for hanging garb, a shelving unit to hold dispensers and bins, and a short bench that we can use for the garbing cleanroom. I will try to round up dispensers and staging tables tomorrow.

Yesterday Keita had Alexa and I mount some optics in tip tilts to prepare for HAM6 work. 

For OM1 we mounted an optic E1201104 SN3 in tip tilt serial number 2

For OM2 we mounted E1100056-1 serial number 12 in tip tilt serial number 4.  

Both of these were pitched downward after installing the optic.  We tried to balance them by turning the bolt that is on the bottom of the mirror holder, but found that for each of them we had to turn the bolt until it was hitting the tip tilt mount.  This is similar to the situation Kiwamu described in https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=7897

We replaced the silvered, 1and 1/2" 8-83 bolts with 1 inch stainless bolts, which is what is called for in D1001396.  I then thought we should try the same thing for the tip tilt assmebly that had been rejected durring the HAM1 work (serial number 9).  With the optic installed and the 1 inch bolt, the mirror was pitched up, we would have needed to add a longer screw to correct it.  I didn't realize that Joe had reclamped the wire in a effort to solve the large pitch seen in HAM1.  

As I tried to remove the optic I chipped it, Alexa has taken photos, one is attached. 

The small pice that is used to put some tension on the mirror (D1001648, the tip tilt nudge) sticks out somewhat into the mirror holder even when the bolt is loose, meaning that we put a lot of pressure on the optics to get them in.  This creates small scraches along the barrel of the optic where the other two contact points are as we push the optic in, and this is where the optic chipped.  This optic had no serial number and an unpolished barrel.  

We have another optic and will clean it this afternoon. 

The chamber was cleaned this morning but the cleaning crew reported that it was quite clean. Bubba and the Apollo crew waited for a go ahead from Cheryl and Mark Barton (HAM Aux TFs?). One door was off before lunch and the second door was taken off right after lunch.

Cheryl asked if we could get TFs for IM2, IM3 and IM4 to complete the IM1 set from 8287 before the HAM door is removed, so I set them going in parallel in three Matlab sessions on opsws7. They should be done by about 11:30 am.
