Second cleaning of spool and the cleanroom over it. Spool was NOT removed today. Garbing/staging cleanroom cleaned. Meeting to discuss what needs to happen to prepare for cartridge build-up and get the cryo-pump baffle installed in a timely manner. Bubba will move one more cleanroom from the LVEA to the end station.

Last week, Gerardo successfully bonded the ears onto ETM08, destined for the monolithic QUAD suspension for H1-ETMx. We will wait 1 month from May 17th before welding and hanging this optic.
Chris, sheila We made a temporary script, C:SlowControls Target H1ECATC1 PLC1 opcIocShells_startWithoutTiming.ps1 (for whatever reason, as soon as I try to post this the backslashes disappear, so I've put spaces where there should be a backslash) that starts only some of the opcIoc shells for PLC1 (most timing channels are not started) it starts: PLC1.in.001.db PLC1.in.012.db PLC1.in.013.db PLC1.in.014.db PLC1.io.001.db PLC1.io.002.db If we use the installation scripts to update, compile and active and run both PLCs, then select only PLC2 to use the restart database script, then go to the target area and run this power shell script, we should be able to use both the picomotors and everything on PLC2 (IMC common mode board, ect) without being extremely slow.
HAMs 1, 3, 5, 6 and BSCs 1, 2, 3 are in flushing configuration now. HAM 2 is in the operational configuration. Fluid was added to the reservoir on Tuesday as it was tripping for low level. Adding HAMs 5 and 6 has made a large difference in the max pressure we've seen from the pumps. Most likely we've cut out the low resistance flow areas now. Once HAM 4 is set to purge there should be another large pressure jump if this guess is right.
We are currently at 52.5 psi from a 1970 pump speed.
P.S. Switching off Servo Control caused a situation where 3 motors tripped out and only 1 motor was being driven from the remote. The other 3 pump controllers needed to be reset and put into run mode to operate normally again.
The fluid level in the reservoir was looking very low and the level switch could not be lowered any further. Re WP 3909, I ramped the pressure down slowly but the ISI still tripped. Fluid was added to the reservoir and the level switch adjusted accordingly. Ramped the motor speed back up, slowly, to ~80psi. Pump driven at 15.2hz; the servo is in manual. We have been unable to get this to drive the VFD; still working on this.
The BSC-ISI models (ITMX, BS, ITMY, ETMY) were modified and recompiled to accommodate the sensor correction path. The test model h1isitst was also recompiled.
The convention for the STS-2s in the seismic model is:
- STS2 - A - Input arm - plugged on BSC1
- STS2 - B - Beer garden - plugged on BSC2
- STS2 - C - Output arm - plugged on BSC3
with A, B, C, the letters used to define the different STS-2s in the simulink models.
At the end stations, STS-2s will be plugged on the B inputs.
The seitst computer (former seib8) was fixed by the CDS group. BSC3 testing on the teststand (without payload) can start.

MC2 transmission QPD (HAM3) was centered using picomotors.
Couldn't center IM4 (HAM2) transmission, picomotors didn't move. Turns out that the cable was not routed from the chamber to IOT2L. Right now a seemingly incorrect cable (SUS something something) is connected to the pico feedthrough (D4-3C2).
After the correct cable was connected in the morning, I was able to move IM4 trans picos to center the beam.
A much-delayed alog: I completed DC and RF calibration checks on both IMC WFS using the 980 nm AM laser. The conclusion is that the WFS work, by and large. For two segments of WFS_B, the readout is about 15% lower than expected. And for both WFS, segments (1, 2, 3, 4) in the DC outputs apparently correspond to segments (4, 3, 2, 1) in the RF outputs. Details below. Devices tested WFS_A: head S1300267 / demod S1001018 WFS_B: head S1300268 / demod S1001034 WFS interface chassis S1200441 AM laser source 4 mW nominal output 0.1 Vpp RF drive at 24.078473 MHz RF input calibration is 13 mW/V => RF power is 1.3 mW Calibration factors WFS PD responsivity at 980 nm is in the range 0.5-0.6 mA/mW WFS PD DC transimpedance is 1 V/mA WFS_A PD RF transimpedance is (0.38, 0.43, 0.37, 0.38) V/mA for segments (4, 3, 2, 1) WFS_B PD RF transimpedance is (0.46, 0.47, 0.40, 0.46) V/mA for segments (4, 3, 2, 1) WFS interface DC gain is 1 (gain setting = LOW) Gain through demod board is 5 V(dc)/V(rf) (front panel) or 10 V(dc)/V(rf) (differential output to ADC) ADC conversion is 1638 ct/V Results Colored as follows: up to 5% deviation 5-10% deviation 10-15% deviation)

Betsy reported that the ITMx ETMx assembly team in the staging building were near the point of needing the X1 quad test stand but that it had lost its settings, so I took a look. It turned out that there was no safe.snap file in /opt/rtcds/tst/x1/target/x1susquad/x1susquadepics/burt , so I created a symlink to /opt/rtcds/userapps/trunk/sus/x1/burtfiles/x1susquad_safe.snap which existed from 11/18/11. It also turned out that /opt/rtcds/tst/x1/userapps/release/cds/x1/medm/X1SITEMAP.adl , was pointing to .../userapps/release/sus/common/medm/quad/SUS_CUST_QUAD_OVERVIEW.adl , which was way too new, so I redirected it to .../userapps/release/sus/x1/medm/quad/SUS_CUST_QUAD_OVERVIEW.adl/SUS_CUST_QUAD_OVERVIEW.adl . The preferred commands for getting the sitemap are now sitemap1 for the quad (login as controls) and sitemap2 for the triple (login as controls3).
Actually, it's ETMx.
On Wed/Thu 5/22-23 I did some more tweaking:
* I redirected the R0 overview screen link on the main screen to .../userapps/release/sus/x1/medm/quad/ .
* I tested the Matlab scripts switch_align.m, switch_comm.m, switch_damp.m, switch_dampin.m, switch_lock.m, switch_lockin.m, switch_master.m, switch_test.m, and switch_testin.m (from ^/trunk/Common/MatlabTools), fixed a few bugs and removed the warning about being untested on X1.
* I tested the Matlab script ^/trunk/Common/MatlabTools/SchroderPhaseTools/Matlab_TFs.m, and fixed a few issues. In particular, it was trying to write the AWG output to a temp file in a directory owned by controls3, so I had Jim Batch set that directory group writable. Also it was trying to log channels X1:SUS-L1_WIT_LMON etc that didn't have _DQ versions, so I commented them out for now.
The Y end system manager has a few times stopped receiving values from the bridge terminal, causing a communications error. going into the system manager, generating mappings and activating the configuration solves the problem, even though the configuration was already activated and other beckhoff modules were already receiving signals.
I did not make this entry.
Sorry, it was me.
