Workers: Michimura,Ushiba,Furuhata,Kambara, Aso

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

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)
