Schedule
(VERY ROUGH)
- 2017/12/06 Project started
- 2017/12/26 Rehearsal of rehearsal
- Before bKAGRA phase1 run (Detailed date has not been fixed): Preparation
- 2018/01/11-12: Preparation of reharsal
- 2018/02/13-15 (option 2/16): Rehearsal of PEM injection (end-to-end test, maybe without actual injection)
- After bKAGRA phase1 run (Detailed date has not been fixed): Injection test in tunnel (4 days)
- After injection test: Analysis, make report, (if possible) write paper
