Type-C suspension
- Type-C suspension is relatively small double pendulum. Among the big suspensions used in KAGRA, type-C is the smallest. Some of them were once used for TAMA300, originally designed by K. Arai in 1990s. So "TAMA-type suspension" is Type-C suspension.
iKAGRA
Five TAMA-type suspensions were used for iKAGRA.
For the final iKAGRA configuration, 6 mirrors are suspended and most of them are Type-C. 3 PO type; MC_i, MC_e, MC_o and 2 TM or RM type; ETMX, ETMY.Work log about 2 iKAGRA ETMs is here.
