=== Sensors and Actuators ===
See [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=2170|JGW-T1402170]] for arrangements of sensors and actuators for Type-A.

Similar arrangements apply for (Fixed) Type-Bp and Type-B.

For Type-C, we have TM actuation only.

=== Abbreviations ===
IP: Inverted Pendulum

F0: Top Filter (GAS filter)

BF: Bottom Filter (GAS filter)

PF: Platform

GAS: Geometric Anti-Spring

IM: Intermediate Mass

IRM: Intermediate Recoil Mass

TM: Test Mass

RM: Recoil Mass
