1 GW detectors in the mine
Kamioka Tokyo 2009 GWDAW, CLIO team

2 CLIO in Kamioka mine 2009 GWDAW, CLIO team

3 CLIO reached to thermal noise in the room temperature
Problem: Eddy current in aluminum coil holders induced by magnets attached on mirror added mechanical loss on pendulum thermal noise Pendulum thermal Mirror thermal Solution: Aluminum holders were exchanged to ceramic and daifron holders. 2009 GWDAW, CLIO team

4 Noise budget Start cooling in this spring to see improved thermal noise! 2009 GWDAW, CLIO team
