SWWD update at the end stations

Following the DACKILL naming decision yesterday, I installed the latest SWWD version of the IOP models at both end stations. The new models are: h1iopsusex, h1iopsusey, h1iopseiex and h1iopseiey. All user models were restarted as part of this install. The h1iopsusey model has test oscillators which sum with the SIDE OSEM signal. I was able to use the oscillator to test the SUS-to-SEI trip and verify SEI DACs are killed after 10 minute have elapsed. At EY I tested the system by PANIC crashing SUS which started the SEI countdown.

To support the HWWD and SWWD install/tests the DAQ was restarted. Note, the corner station IOP models were make/make-installed but not restarted today, which is why their DAQ status is now 0x2000. This will be remedied when these models are restarted at a later date.

Alignment of ITMx complete

J. Oberling, A. Pele, myself

Alignment of both M0 and R0 of ITMx have been completed, at least until someone tells us otherwise. Pitch adjusters have been locked down and all levels of OSEMs tuned to medium-fine. Stay tuned for alignment values and TF results.

Testing of the HWWD and SWWD at EY

Rolf, Jeff, Jim, Dave

This afternoon we tested the HWWD and new SWWD side-by-side at EY.

HWWD: the HWWD unit is connected in monitor only mode. Its front two monitor ports are cabled to the main-top OSEM satellite amps for ETMY. Its binary in and out cables are connected to ports 24-31 on the binary input and binary output chassis for ETMY. 3 of the 4 front panel BNC ports are connected to spare BNC ports on h1iscey's PEM AA chassis. The back RMS monitor BNC port is also connected to a spare BNC port on the h1iscey PEM AA chassis. We configured the system with a trip point of 110mV and a trip time of 2.0minutes.

SWWD: the h1iopsusey model was built this morning with the latest SWWD parts using RCG2.8.4. The hard-coded RMS trip point is 110mV.

h1susey: the h1susey model was modified to include a HWWD part to communicate with the unit via binary in/out. This required h1susetmy to be compiled against RCG-branch-2.8 to use the new part.

Jeff excited BSC10 at EY using the HEPI actuators. He will post the details in a separate entry. We were able to transition both the HWWD and SWWD to their count-down-to-trip state within the same second. In the attached dataviewer plot. Top Left: the analog voltage from the HWWD back RMS port (being read by h1iscey). Lower Left: is the EPICS channel from the HWWD part in the h1susey model. Top Right: F1 RMS EPICS channel from the SWWD model. Lower Right: output of the SWWD RMS port.

Within the same second, the HWWD turned on its PD front panel led and the SWWD transistioned its output from 1 (good) to 0 (bad). The HWWD RMS value was about 95 at the transition (950 on the plot but the h1iscey PEM AA chassis has an internal gain of x10).

arnaud.pele@LIGO.ORG - 15:46, Friday 27 June 2014 (12520)

Transfer functions ran yesterday in the staging building are showing clear sources of rubbing especially in the pitch/length/yaw degrees of freedom for the reaction chain. Main chain has large unexpected cross couplings in pitch.

arnaud.pele@LIGO.ORG - 12:36, Tuesday 01 July 2014 (12570)

Andres and Jeff realized the cover was on during that measurement, which is why results were bad. We started them again Friday overnight.

install of RCG tag 2.8.4, building and testing IOP models against this

Rolf release RCG tag 2.8.4 today. I have installed it on h1build, and compiled/installed all SWWD IOP models against this. I also compiled h1lsc model but did not install, just to check the compile.

I am testing the new SWWD models and MEDM on the EY SUS and SEI systems at the moment.

All release pointers have been set to RCG-2.8.4, please keep this in mind if you build FE models.

new features in cdsutils

I forgot to mention yesterday that the new cdsutils install includes a couple of new userful features:

New library:

pydv: this is a simple library for plotting time series of NDS channels. It is what is used by the "lockloss" utility we put together at LLO.

New cdsutils commands:

dv: simple time series plotting, like a very basic dataviewer with a much better plot window/gui:

cdsutils dv H1:SUS-ITMX_M0_OSEMINF_{F1,F2,F3,LF,RT,SD}_INMON

audio: rockifo replacement. play an NDS channel over the local computer speakers:

cdsutils audio H1:LSC-DARM_OUT

I removed the rockifo script, which has now been deprecated.

ITMx Alignment

IAS: J. Oberling

SEI: H. Radkins

Measured the position and yaw of ITMx yesterday after the HEPI actuator install. Position/yaw errors are as follows:

Longitudinal: -0.3 mm (South)
- Tolerance: ±3 mm
Lateral: +0.2 mm (West)
- Tolerance: ±1.0 mm
Vertical: 0.0 mm
- Tolerance: ±1.0 mm
Yaw: 7 µrad CCW
- Target: 0 µrad
- Tolerance: ±50 µrad

As Hugh mentioned in his alog here we used the HEPI RZ position loop to align the yaw to it's current value. Today we will begin work on ITMx pitch and CPx pitch/yaw.

- SUS needs to do pitch work on ITMX

- Higher dust counts recorded on ITMX (~1000's) than HAM chambers (~10's), this is due to too many volumes open at the same time in the LVEA.

- ISS work on going in HAM2, beam was blocked at MC1 and MC3 for redundant protection.

- Sheila and Kiwamu are preparing for beam splitter install at HAM3

- Jason is going to do a shot and prepare for HWS alignment from the ITMX spool

Particle Counts BSC3

Particle Counts were taken in BSC3 before and during work activity on the ITM quad.

Counts were very high, see below. Work continued because the ITM will be cleaned again before close and because of pressing needs from other groups.
Refer to LIGO-T1400024-v4 (https://dcc.ligo.org/LIGO-T1400024) for guidance on particle counts. Would like to see push and draw cross-flow system setup at BSC3.

On Thursday 26th June (following these counts being raised at the morning LHO meeting Bubba et al set up the draw fan on the BSC3 door (opening) as per the attached picture, DSCN0367.jpg. Following the installation of the draw fan I went back to take readings in and around WBSC3. The readings were as follows: - 1) In clean-room outside WBSC3/1 (in middle of room). 0.3 um 50 1.0 um 20 2) In clean-room outside WBSC3/1 (adjacent to draw fan). 0.3 um 10 1.0 um 0 3) In clean-room (in front of draw fan). 0.3 um 150 1.0 um 30 4) In WBSC3 (at opening). 0.3 um 80 1.0 um 10 5) In WBSC3 (just inside chamber). 0.3 um 170 1.0 um 40 6) In WBSC3 (above open flooring, below ITM). 0.3 um 260 1.0 um 70 Clearly the installation of the draw fan has made a marked improvement. However, more measurements are required to confirm this in the longer term. Refer to alog entry https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=12529 for follow up reading taken on the 30th June 2014. ACTION - At next opportunity i.e. when optic can be protected by lens cap the floor (of the chamber) and the flooring should be wiped and vacuumed. Jeff Bartlett has this on his to do list.

ITMx rebuild/install work

Because the Hartman WFS alignment was going to need the ITMx optics free of FirstContact, we pulled it yesterday. However, we first re-re-removed the QUAD sleeve structure and the 4 vibration absorbers which are in the way of the pitch alignment due to take place today. Also prior to removing the FC, we also found high particle counts in the ITMx chamber. Hugh played around with purge (again) and we closed up the small IAS window at the spool. This seemed to improve things a bit. After taking data on particle counts for a while, we proceeded to pull the FC anyways knowing that we'll have to reclean the optic befor chamber close up.

guardian core upgraded; all nodes restarted

This afternoon I upgraded the guardian core to r1020, and cdsutils to r250. There are a couple important new guardian features that I wanted to pull in:

There is a new NONE pseudo-state request. When the request is NONE, guardian does not calculate a path away from the current state, or change states one the current state is complete. Jump transitions are honored, though. This could also be considered a "follow" mode of operation, where jump transitions can be used to track the state of the system without controlling it. This is also now the new default REQUEST state on startup.
More robust handling and recovery from loss of channels. If, during the course of state execution, there is a channel access error (connection or write), the guardian will go into a "connection error" mode. This will show up in the node as an error (red background) but it will continue to attempt to execute the current state method until the error clears. This allows guardian to ride out front end or subordinate node restarts and recover somewhat gracefully.
Other minor improvements and bug fixes.

I then restarted all nodes with "guardctrl restart --all". All SUS nodes had been shut down for the moment, and all SEI nodes are in watchdog trip states, so this didn't do too much. Some nodes that don't specify initial request states came up with the new NONE request. I set manually reset the requests for those nodes back to what they were before the restart. No major issues:
