List of possible small upgrades
- This is a list of possible small upgrades. Current KAGRA design is not optimal considering sensitivity, because of budget constraints, schedule, and lack of careful design.
Cryopayload-related
- Fibers too long and we cannot cool mirror down to 20 K
- Marionette magnets for actuator too small
IFO related
- Curvature of ITM/ETM
- Currently RoC = 1.9 km, because we didn't have reference spheres
