1 Commissioning Procedure for bKAGRA Phase 1 (2017.9-2018.3)
JGW-T December 16, 2016 Updated based on latest schedule on June 12, 2017 Commissioning Procedure for bKAGRA Phase 1 ( ) Yuta Michimura Department of Physics, University of Tokyo see, also, JGW-T for interferometer design and commissioning schedule

2 Major Updates v X and Y CRYp installation almost at the same time (much earlier X installation) - MICH lock at room temp. before cooling down (instead of cooling ETMY first) - AS cannot be used when room temp. lock since SR3 is not ready - SR2 won’t be ready by Phase 1 deadline
