>From: Bill Tyler tyler@ligo.caltech.edu

Nothing significant to report this week.

LIGO Hanford Observatory (LHO) and Interferometer Operations (Raab)

Summary of S5 Activities at LIGO Hanford Observatory  (compiled by M. Landry)

Quakes, and H2 laser troubles/ISCT10 issues kept the duty cycles a little lower than the recent weeks: H1 ran at ~14-16Mpc 88% of the time, while H2 ran at ~6-7Mpc 82% of the time.

Some highlights from the elog are below:

• summaries: Tuesday maintenance, latest range & duty cycle compilation
• H2 NPRO cooling lines were found to be obstructed, so the were replumbed and the laser noise returned to nominal levels
• Weiner filters prepared for a CIT Newtonian noise study may also be used to extract more performance out of useism/pepi feedback loops , which use DARM_CTRL as an error signal and feedback to the fine actuators
• the magnitude 8+ Indonesian quake, and subsequent aftershocks, caused the ifos to lose lock and suffer increased noise when locked

Outreach (D. Ingram)

• In a piece of new business for outreach, LHO hosted a visit from ~20 Portland-area tour operators on 9/11. The operators were in the Tri-Cities for a 2-day visit, sponsored by the Tri-Cities Visitor and Convention Bureau, to evaluate local attractions for the possibility of scheduling future tours. LIGO is a member of the TC VCB.
  

LIGO Livingston Observatory (LLO) and Interferometer Operations (Giaime)

S5 run (Igor Yakushin):

• Most of the week the range was around 15Mpc except for the last day or so when we had a lot of seismic activity (earthquakes in Indonesia, Hurricane Humberto). Despite of the nearby logging the duty cycle for this week was 73%. 3.61 Hz wobbling of yet unknown origin was observed during this week.

CDS computing (Lisa Bogue):

• Working on email masquerading problems with the wiki.
• Working on ldap.
• Still working on the t1000's
• Working on maintenance contract renewals

Commissioning vacuum prep (Tom Evans):

• We have received the first shipment of vacuum parts for the Faraday isolator for E-Ligo from UF, and are preparing to clean and bake the parts. We should receive additional Faraday isolator parts soon, and we also have seismometer pods to be baked.

40-Meter Interferometer (Weinstein)

• Rob is returning to the task of locking the full dual-recycled FP Michelson configuration in order to measure laser and RF oscillator phase- and intensity-noise couplings in both RF and DC readout.
• Tobin, Rana and Andrey were trying to lock the DRMI and they needed more RF sideband power. Using the optical spectrum analyzer, they adjusted the modulation depth for both the 33 and 166 MHz sidebands to get Gamma = 0.22.
• Tobin found and fixed a broken cable that prevented us from reading the N2 pressure. Now it reads correctly, and under-pressure will trigger a vacuum interlock. Steve tested this and it worked perfectly. IN the process, we rebooted the c1vac1 processor for the first time since Feb 2006. Rebooting has no ill effect on the vacuum controls.
• More computer problems: The iscepics process on the c1dcuepics computer died spontaneously. Tobin restarted it, but if it keeps on failing, we may need to get another computer to run it on.
• Andrey re-worked the video switch MEDM screen so that it is more intuitively oriented.
• Elena continues to develop her adaptive filter for feed-forward noise cancellation of ground-motion.
• Valera is here, to work with Sam on the eLIGO OMC construction. Sam is gluing up the optics and running tests.
• Steve replaced the tp3 dry scroll pump, after over 8000 hours of service.

Thermal Noise Interferometer (Black)

• This week we bid farewell to Ilaria, who returns to Benevento after a successful six-month visit.
• All of the mode-cleaner mirrors are now suspended and damped, and all of the steering optics leading up to the mode cleaner are in place. Akira has started gluing magnets on the arm-cavity mirrors.
• Electrical wiring is complete on the South 110V outlets and the roughing-pump 220 line. The North outlets are nearly done.
• Greg is in Livingston doing a scimon shift.

LASTI (Mittleman)

BSC ISI

• We ran into trouble with the small actuator installation and had to redo it. There was a problem with the initial assembly of the stages (mostly stage 1) and although they fit together the walls aren’t as perpendicular as they should have been. Were this has gotten us in trouble is that the actuator brackets do not have 6 degrees of freedom of adjustment but rely to some extent on the stages being in the location and orientations. We have managed to shim the actuator brackets to allow assembly, but at some point we are going to have to figure out what we missed in the assembly process. We did not have this particular problem ion the dirty assembly so we are pretty sure that it is possible to do it correctly.

Lasti Vacuum

• We have broken vacuum for modifications to the pondermotive experiment.

Kari Hodge

• I have been debugging my neural network code, through which I am currently running low mass H1L1 triggers from the S5 playground.
• First, I made new input arrays (with triggers from both two and three ifo time) so that the time slide and injection regions would have more overlap in effective SNR, since that is where all the work is.
• Second, I am trying to understand why adding certain parameters, like eta (even though the distributions of eta are not physical, so it would not actually be an input into the final neural net), cause a 'squashing' of the neural network's output from 0 to 1 to 0 to ~.6. I am investigating this behavior because it implies that the neural network does not find even the injections in my testing set to be more than 60% signal like, which is odd considering that my testing set should be statistically similar to my training set.

Laboratory Computing (Anderson)

LDAS Software Systems (Maros)

• System test integration (PR#3069) continues to dominate the development efforts. Some of the more complex tests are being integrated. The new model that is being used will allow for single button testing and a summary report of simple pass/fail results. This eliminates the tedious (and potentially error prone) task of visual inspection of result files.

Advanced LIGO Systems

Modeling and Simulation

From: Sanichiro Yoshida <syoshida@selu.edu>

I put together our group's weekly for Hiro.

Modeling and simulation (Sany Yoshida)

Based on Mark Barton's most updated mathematica model, Richard created a state space matrix in the e2e format. This model simulates the Adv LIGO quad suspension taking the violin dynamics into account. We tested the model by including the state space matrix in our e2e quad sus code. For the position (translational motion normal to the mirror surface) DOF, the resultant power spectrum shows a peak around 420 Hz, as expected.

e2e weekly meeting

Attendees: Osamu Miyakawa, Richard Williams (SLU undergraduate student) and Sany Yoshida

We discussed the progress on e2e modeling of the Advanced LIGO baseline HAM seismic isolation. The Southeastern team has made an e2e model based on a matlab model provided by the SWG. The computed table top motion seems to be reasonable, but needs to be verified by the SWG. Osamu confirmed that he could still use the simplified HAM seismic isolation model for his e2e Advanced LIGO optics simulation so that the Southeastern team would have some time to verify the HAM seismic isolation model. We also discussed possible Southeastern student's visit to Tama next summer.

Static IFO simulation (Hiro)

Hiro was on vacation.

Modeler : e2e simulation engine and ALFI : e2e front end (Hiro, Bruce, Melody)

(Melody Araya)

ALFI

• Worked on the draft for the Use of User-Defined Primitives in ALFI. Integrated Bruce's changes into the document.
• Installed a standalone version of ALFI 6.6.2 in Hiro's laptop.

CDS Prestabilized Laser

From: Peter King <pking@ligo.caltech.edu>

• In going over the requirements for the laser diode enclosure, I found that the interface document was sadly out of date - it dates from when the laser still had an injection-locked front end.  I have been updating the interface and signals, keeping in mind the division between local control by the Beckhoff Automation hardware and EPICS.
• I finally finished laying out the circuit board for a quadrant photodetector. Parts for said board arrived from Digi-Key.
• Benno has started drafting a testing plan.  It's in point form at the moment as we are deciding which tests to include (and where).
