 Three are PickOff type; MC_i, MC_e, MC_o and 2 TM(TestMass) or RM type; ETMX, ETMY.  Three are PO(pick-off) type; MC_i, MC_e, MC_o with the mirror thickness with about 3cm, and 2 are TM(TestMass) or RM type; ETMX, ETMY with the mirror thickness of 6cm.

Type-C suspension

  • Type-C suspension is a relatively small double pendulum with intermediate mass passively damped with eddy current damping. Among the big suspensions used in KAGRA, type-C is the smallest one. Some of the type-C were once used for TAMA300, originally designed by K. Arai in 1990s. So type-C suspension is sometimes called as TAMA-type suspension.

iKAGRA

  • Five TAMA-type suspensions were used for iKAGRA.
    In the final iKAGRA configuration, 6 mirrors are suspended and 5 of them are Type-C. Three are PO(pick-off) type; MC_i, MC_e, MC_o with the mirror thickness with about 3cm, and 2 are TM(TestMass) or RM type; ETMX, ETMY with the mirror thickness of 6cm.
