OPERATOR WEEKLY OVERVIEW

Operator team continues to run H1 in the closing days of ER8 & offer H1 assistance where needed.

On 9/10 we had a training by Mike Landry on checklists for triggers & the Rapid Response Team.

Many thanks to the LLO staff for all of your hard work in executing ER8 and coordinating with all of our downstream stakeholders.

Work is in progress on the full recovery of the HPO. A risk assessment of the plan to recovery the HPO was briefly reviewed at the monthly OMT/Detector Engineer Group Leader meeting.

O1

The first observation run started this week. Many thanks to all the local staff for getting us ready for observations.

LSC Fellows

The second quarter LSC Fellows are on-site and working both on their own projects and on Data Quality and Detector Characterization issues related to the O1 data.

The fellows are in the control room 16 hours a day during O1 (with help from some local LSU and University of Mississippi colleagues).

In addition the Fellows will be part of the team that does rapid follow-up for any alerts that we will send to our EM partners.

The fellows are:

Guillermo Valdes from University of Texas at Brownsville. Guillermo will be working on monitoring TCS performance (working with Aidan Brooks remotely). Mentor: B. O’Reilly

Jess McIver from Caltech. Jess will be studying seismic transients. Mentor: J. Giaime

Ryan Goetz from the University of Florida. Ryan will be looking at RF amplitude modulation of the beam exiting the input mode cleaner. Mentor: M. Heintze

Filipe daSilva from the University of Florida. Filipe will work on noise regression using PEM channels. Mentor: A. Effler

Alex Urban from the University of Wisconsin, Milwaukee. Alex will be working on EM followup, GRB alerts and Calibration. Mentor: J. Betzwieser

LIGO India Update
Fred Raab

Arun Srivastava, Secretary, AEC, and Head, International Collaborations and Planning Division, our LIGO-India contact at the DAE of India, did not have further news last Thursday on the status of the cabinet note at the Prime Minister’s Office.

I am currently awaiting from Tarun Souradeep an indication of the status and plans for release to LIGO of the engineering consultants’ reports on two potential LIGO-India sites. This could affect the timing of a potential fact-finding trip to India.

The RRCAT team is preparing to review the mechanical drawings completed by the IPR team for the LIGO-India vacuum system to ensure compatibility of interfaces for future detector installation. Additionally the team is working on a laser pre-amplifier with a goal of achieving 35W operation by July 2016. A Reference Cavity is also under construction. Outside the LIGO-India team at RRCAT, there is an internal RRCAT committee that is vetting construction plans for their prototyping laboratory.

The IPR team has already sent vacuum system drawings to LIGO (MZ and JW) for comment. They will be sending these same drawings to RRCAT for their review in parallel.

There are now bi-weekly instrument science telecons occurring in India to share and broaden knowledge related to LIGO-India instumentation.

1) Air Nozzle Vacuum & Optic Illumination System Working on commissioning the vacuum system for the above setup. Torrie, Gushwa and Taylor.

2) Bounce roll mode damper (BRD) Working on commissioning the vacuum system for the above setup. A single BRD is mounted inside our 4 ft vacuum system in order for us to measure the Q. Building a single pendulum setup for this effort too. Torrie, Robertson, Taylor.

3) Chevron Baffle Working with Coyne and Zucker on the Chevron UV baffle for Varian 2500 l/s ion pumps. Sanchez and Torrie.

4)Lower quad in vacuum. Working on setting up the feed-throughs, data loggers and electrometers that will mounted to the lower quad inside our 4 ft vacuum system. Torrie, Baric, Guswha. (Weaver coming to support us on build and install of lower quad.)

  1. Preparing some modified ETM ESD drivers for shipment to LHO. The modifications will bring these three units up to the latest revision providing enhanced dynamic range and better frequency response of the monitoring channels.
  2. Evaluating various technical solutions to inventory management including:RFID, 1D and 2D barcodes. These technologies would be married to a software solution.
  3. Reviewing materials for Squeezing review this Friday.

Finishing up final runs for search methods paper (74h on-source regions for M82 host galaxy). Created functionality in SMEE to run using condor. Added 3D injection waveforms to SMEE. Met with Siong and Jade to discuss updated arrival time prior based on oLIB/cWB triggers. Ran distance and 10kpc runs for time domain PCs with updated prior. Began preparing slides for LIGO seminar.

Worked with search chairs and pipeline developers to understand, document, and plan aLIGO computing demand and performance optimizations, and to compare recent usage with earlier projections. Appointed as co-chair of LSC Computing and Software Committee. Discussed aLIGO and LSC DA computing management plans. Worked with OSG and Georgia Tech LSC group to test cWB pipeline with OSG interface to Georgia Tech HPC resources.
