CLIO has many interferometers. One is a laser interferometer with 100m baseline for GW detector. The others are three interferometers with 100m baseline for geophysics.

CLIO displacement sensitivity has reached thermal noise levels of the mirror substrate and its suspension wires at the room temperature. At present, we are trying to demonstrate these thermal noises will be reduced by cooling mirrors and suspension wires.

Offset Locking

Inverted Pendulum at Kamioka

Local Suspension Point Interferometer

Data gaussianity of CLIO is better than TAMA300 (preliminary result).
