CRY payload actuator upgrade in 2020

Kick-off meeting

2020/5/27 10:30 - 12:00 Zoom: KAGRA Zoom2

Goal of the meeting

Decide the followings

Deliverables of the work

A document to answer the following questions

  1. Does the expected actuator noise level satisfy the KAGRA requirement ?
  2. Can we lock the interferometer with the modified actuators ?
    1. Is lock acquisition possible ? (ignore noise)
    2. Can we keep the lock with weak damping ? i.e., not injecting excess control noise from strong damping
  3. Can we damp all the resonant modes of the CRY payload within reasonable time (like 1 minutes) ?
