After the SEI guys locked up the HAM4 ISI I went in and locked up the face stops of the intermediate and bottom mass of SR2. Like in HAM5, I noticed a lot of EQ stops were pulled back a long way and so using an inspection mirror/flashlight combination I have set EQ stops closer (where appropriate) and locked the EQ stops nuts into position (as best I could). Thus to lock and unlock the suspension  from now until closeout should only require locking and unlocking the face EQ stops of the intermediate and bottom mass.

To enable FC'ing of the mirror to happen I marked the position of the TCS mirror in front of SR2 with dog clamps and removed the mirror (see pics below)

SR2 should now be ready for FC'ing

Following the connection of the SEI control signals out of the HWWD chassis to the ISI Coil Drivers, we changed the HWWD settings to nominal:

We also changed these settings in the h1susetmy_safe.snap file and committed to SVN (r8402)

After the SEI guys let me know HAM5 ISI was locked back up I went in and locked the face stops of the intermediate and bottom mass of the SRM and SR3 suspensions. I then used dog clamps upside down to mark the position of the baffle in front of SR3 and removed it so that the SR3 optic can be first contacted.

I then had a look around both suspensions and noticed that a lot of EQ stops were a long way back. I have gone around both suspensions using an inspection mirror/light and moved EQ stops closer and locked (as best I could) the EQ stop nuts so that the EQ stops should not move. This includes moving three of the 4 EQ stops underneath the intermediate mass of SR3 closer (I couldnt get an an angle to adjust the fourth one closer, but I could do up the nut). When it comes to unlocking and locking the suspensions from now until closeup should only require moving the face stops of the intermediate and lower mass.

The suspensions should now be ready for first contact to be applied

I also whilst in the chamber wiped out the inside of the bellows, etc. If you asked me if it was necessary, see the pic for an example of the sort of stuff was getting on wipes when wiping out the bellows

we added a 2Hz low pass filter on the RFPD filter module within the FSS model and turned it on. I moved the H1PSLFSS.txt file to the userapps area and checked it into SVN (r8401).

Rebalanced the ISI and ended up removing 0.8lbs and moving other.  Not too bad and a well within spec lock/unlock with worst shift of ~400counts (1600 spec.)

The ISI is unlocked and SUS has now unlocked the SUSes and we'll set up for TFs tonight.

Attached are the spectra from last night TFs from HAM4.  SR2 as well was undamped and the extra wiggles are right where the SUS resonances are positioned (VC-APele.)  Otherwise these look about as clean as has ever been seen for HAM4.

The ISI is now locked for First Contact.

The following cables at HAM2 were checked:

ISC_243 PSL SM2 QPD. Feedthru D4-3C2
ISC_244 Picomotors. Feedthru D6-F10

ISC_243 was checked at IOT2L cable end. Cable is currently disconnected since table is temporarily moved.
ISC_244 was checked at IS_R4 rack. The QPD Amp chassis was powered down before disconnecting cable at rack side. 

All cables checked out. All cables were reconnected and electronics powered on.

As part of the flurry of activities yesterday, I took TF's on the HAM5 ISI. They look messy, but I realized when I got in this morning that some of the suspensions were not damped, so I think I understand why my data looks bad. There are extra peaks that look like suspension resonances, but the responses look kind of like L1 HAM5, if you squint and ignore some detail.I've attached images for my TF last night (first 2 pdfs), and my best guess at the equivalent at LLO (second 2).

Additionally, we had an actuator that was plugged in backwards ages ago, that we had fixed by adding a gain of -1. Somehow this electronic fix had disappeared, so one of the actuators shows a -180 phase. The plan was for Fil and I to go in, take the plug apart and fix this at the chamber wall, because accessing the cable on the actuator is almost impossible. But, it turns out that the planned fix involved cutting the cable, and we don't have length to spare on this one cable, it barely reaches the flange uncut. So, I went in and unplugged the cable and replugged it correctly, completely blind. Only took about an hour. 

Did continuity test on TCS RTD (Resistance Temperature Detector) for HAM 4 and 5:

HAM4 Flange D6-3C1 (air side)
HAM4 Flange D3-3C1 (air side)

The following pins at each connector are tied together:

Pins 1&2
Pins 14&15
Pins 11& 12
Pins 24 & 25

Read ~110ohms across:

Pins 1&14
Pins 11&24

All within spec.

Both HAM3 suspensions are locked. The wafer for mobility experiment placed back into position. Vertical wafer holder (no wafer) placed into position. 1" optic placed on the side of the MC2 cage. Optic still has FC on it. ISI now ready for balancing

Changed out ISI coil drivers in SEI rack C1 with modified chassis with SUS Watchdog Interface and connected coil drivers to watchdogs.

Replaced 
S1103301 U6 with S1103303
S1103316 U4 with S1103309
S1103361 U2 with S1103356

Pcal transmitter module was delivered and installed on top of the pylon at the EndX station.
Pcal receiver module parts were delivered to the EndX station. The module was assembled and installed into the pylon, but not yet aligned.

Port (window) shutter was installed on the receiver side.

Enclosure of the receiver module is currently not installed. Proximity sensors for receiver module enclosure have been tested, but were removed for additional tests.

We noticed that the h1iopsusey ADC bit (3rd bit) in the STATE_WORD has been coming on since wednesday evening. The IOP model was upgraded to RCG2.9 at noon on wednesday. We downgraded the IOP model to RCG2.8.4 this morning, and took the opportunity to also downgrade the h1susetmy and h1sustmsy models. No DAQ restart was required.

It looks like the data from the ETMY STS is not getting saved to the frames correctly. If you look at the attached plot, it shows an ASD of the ETMY STS. I've plotted  both the data (5 minutes of data starting at 17 July 00:00 UTC) from the SENSCOR channels (H1:ISI-ETMY_ST1_SENSCOR_GND_STS_X/Y/Z_FIR_IN1_DQ) and ISI-GND channels (H1:ISI-GND_STS_ETMY_X/Y/Z_DQ) - no filters have been applied, this is just the raw data. The SENSCOR channel looks fine so we do not think the sensor is broken, but the data isn't being saved correctly to the H1:ISI-GND_STS_ETMY_X/Y/Z_DQ channels. 

Summary - Data is not being saved correctly to the H1:ISI-GND_STS_ETMY_X/Y/Z_DQ channels.
