iKAGRA PR2 alignment & Beam Profile Measurements
Date: 2016/3/3
Workers: Michimura,Ushiba,Furuhata,Kambara, Aso
Objectives
- Center the beams on PR2 and PR3 mirrors
- Measure the beam profile in front of PR2 and PR3
Procedure
- Enter the tunnel, check necessary tools
- Setup KOACH filters near the PR3 chamber
- Setup KOACH filters near the PR2 chamber
- Open the flange of PR3 (on the +X side)
- Open the flange of PR2 (both -X and +X sides)
Lock the MC and send the beam from IMMT2 to PR2 with low power (<2mW)
- Center the beam on PR2 using IMMT2 picomotors
- Center the beam on PR3 using PR3 picomotors
- If the beam on PR3 is too dim and difficult to align
- Declare the laser hazard area. Distribute laser goggles to people in the center area
- Increase the power from MC (to 25mW or so)
- Measure the beam profile in front of PR2 using the middle size beam profiler
- Measure the beam profile in front of PR3 using the large beam profiler
- Stop the beam from MC
- Declare the finish of the laser hazard
- Close the flanges
- Cleaning around the chambers
- Stop KOACH filters
Necessary items, tools
- Middle size beam profiler (check with Doi-san)
- A stand to hold it at the right height
- Large size beam profiler (need to find where)
- A height adjustable table (check with Saito-san)
- Two PHS phones for communication between PR and BS area clean booths (or transceivers)
- Two sets of floor KOACH
- Clean suits and inner ware
- Chamber compatible type
- A wrench to turn the bolts for the flanges
- A PC (or two) for controlling the picomotor (check with Kokeyama-san ?)
- Prepare a joypad as a backup (need to find one)
- A lot of laser goggles (collect them beforehand)
- Sensor cards (check with IOO people)
IR viewer (check with IOO people)
Notes
- Divide the team of 5 into 2-2-1 (PR area - BS area - outside the clean booths)
- Who will operate the MC ?
