This morning I went into BSC1 to re-resume work on the ITMy SUS.  Particle counts taken this morning are as follows:

0.5um  40

1.0um  20

In BSC3 near flooring, after wiping flooring and walking around a few minutes

0.3um  540

0.3um  270

0.5um  100

1.0um  80

I had to repair the false CR wall around the BSC3 door this morning because I found it had falled down sometime since last Wed.  Note, if doing this type of false wall in the future, tape needs to be added perpendicular to the joint tape, to make reinforcing "stitches" across the sheet joints.

Dave noticed that the IOP software watchdog for EY was not active. We found that the watchdog had been tripped since ~11am last wednesday (7/2/14). The IO chassis had been restarted at that time but the IOP watchdog had not.

No visitors expected this week.

only h1fw0 restarts, there were 31 of them.

only h1fw0 restarts. 38 in total, see attached text file.

h1fw0 is unstable, but provided h1fw1 continues to be stable there is no data loss. LDAS are automatically archiving h1fw1's frames when they are unavailable from h1fw0. The default NDS is h1nds1 (which reads h1fw1's frames) so there is no discontinuity of data for NDS clients. The current uptime of h1fw0's full frames is 85%.

We aligned the in-chamber HAM4 HWS optics using the IAS beam this afternoon.

1. Matt adjusted the alignment of SR3 to center the IAS beam on SR2.

2. I confirmed the beam was centered on HWSY STEER M1 (the transmission through SR2).

3. I adjusted HWSY STEER M1 to center the beam on HWSY STEER M2

4. Matt adjusted HWSY STEER M2 to center the beam on HWSY STEER M3

5. Matt adjusted HWSY STEER M3 to center the beam on the HWSY VAC LENS. This also centered the red beam on the installed viewport emulator.

6. Matt adjusted the HWSY DCBS by M2 such that the reflection off this optic, which will be 1064nm leakage, was captured by the HWSY scraper baffle (in the crook of the baffle on the -Y side of it). He also confirmed that the beam was centered on that DCBS. There were two reflections from the DCBS that were horizontally separated. 

7. I adjusted HWSX STEER M1 to center the beam on HWSX STEER M2. 

8. Matt adjusted HWSX STEER M2 and M3 to center the beam on M3 and on the viewport emulator (without HWSX VAC LENS installed)

9. Matt installed HWSX VAC LENS to return the beam to the same point on the viewport emulator

10. Matt adjusted HWSX DCBS to put the reflection of the red beam off that optic into the crook of the HWSX scraper baffle in the -Y direction. There were two reflections from the DCBS - one was at the same height as the incoming beam and the other was angled down and in the -Y direction. 

11. Since I'd forgotten this step to start with, I moved HWSX STEER M1 ~5mm parallel to its surface to make sure the beam was centered on the aperture of that optic. The distance of the beam from the edge of the aperture is shown in the attached PDF. We also placed a target far downstream of this optic, noted the position of the beam before the optic was moved and returned the beam to that position after the optic was moved to ensure the alignment was not affected.

Photos of the optics are attached. We took several shots of HWSX STEER M1 and HWSX STEER M2 as these optics were moved from what is shown in the H1 HAM4 assembly drawing.

This is a summary of the state of the HAM4 and HAM 5 chambers:

HAM5

• The ISI is half locked. The lockers on the south side are locked, but on the north side free.
• SR3 all stages are locked...however the optic is locked in such a way that it sends the HeNe from the SR3 optic onto the centre (ish) of the SR2 optic (still needs investigation into whats going on with SR3 pitch)
• SRM is unlocked.
• Nothing moved on HAM5 table by me/us

HAM4

• ISI is locked
• SR2 is unlocked
• HWS optic positions on table were moved so a rebalance of ISI necessary
• I noticed (the hard way), that it appears that at least 3 of the top mass weights on the 2 stack high SEI masses on the ISI are not bolted to the bottom weight and so can thus move. From memory one is by the north door, one in centre (ish) of the table and one on west side of table
• Note: I believe because of the low purge air a bug flew into the chamber and onto the table. Luckily I was able to get him and wipe in that area, but we need to be vigilant and make sure soft door covers are up when not actively working in the chamber

Aidan will write an alog regarding the alignment of the HWS optics in HAM4, this is more about the setup to do it.

We haven't been able to solve why the SR3 is pitched low and so I locked the face EQ stops of all three stages, then with Jason making sure the pointing of the HeNe of the total station was correct and that the beam splitter offsets were engaged and damping on, and Aidan standing at HAM4 directing me using the headsets, I altered the EQ stops on the optic of SR3 so as to steer the beam onto the center of SR2 optic (or as close as we could tell it was to center).

This was enough to allow the alignment of the HWS to begin. Just for curiosity we looked at how the beam was going from SR2 to SRM. Luckily we could see it and so we could steer the HeNe beam onto roughly the centre of SRM with ~1500 offset in pitch and ~1800 offset value in YAW on SR2 upper mass (note Jason seemed to think that the sign of which way the beam went up and down when he provided an offset was flipped. Maybe someone wants to look into that).  So thats a good sign.

Note: The HWS optics were aligned WITHOUT any offsets applied to SR2.

As we discovered yesterday, two HWS optics (HWSX STEER M1 and HWSX STEER M2) and the HWS scraper baffle are out of position with respect to each other. It turned out that the assembly diagram for the H1 HWSX HAM4 optics is incorrect (when compared to the actual optical coordinates, E1100463, derived from the HWSX optical solution, T1000179). Also, H1 and L1 coordinates are supposed to be the same. The following table summarizes the problem in the documentation:

So ... we have moved the offending HWS-X mirrors (HWSX STEER M1, HWSX STEER M2 and HWSX STEER M3) in HAM4 to the correct positions specified by the L1 assembly diagram. We will update the H1 assembly diagram to reflect this. Photographs will be attached ...

Alignment of the HAM4 HWS optics with the IAS laser is taking place this afternoon ..

And she's not even here today .....

Betsy located some aluminum ClassA parts yesterday that we were able to use today to improvise some strain relief for the PSL ISS PD array cables in HAM2.

Jeff and Michael were able to locate some PEEK cable ties (very handy) that we used to dress the cables to the improvised bracket (see attached photos).

Peter is doing one final set of electrical tests now, after which we will consider the ISS PD installation complete (and successful).
