Past week report
- PRM installed
- The suspension was installed.
- But we found that the tank cannot be placed at the +y side of the PRM, since the space inside the clean booth was so tight. The tank was moved to the -y side using the fork lift and crane thanks to Kimura-san, Sawada-san, and Endo-san.
- Cabling was almost done, but not yet checked.
- Pylons for oplevs are installed. But no view port, nor oplev setup.
Plan for coming weeks

Past week report
*Waiting for concrete information on installation location.The type(High power,Low power)and number actually needed,and the peripheral equipment accompanying it.-->Waiting for information provision.
