Arai does not know which specific TAMA suspensions we will take from TAMA. It is TBD. At least, there is one PO type suspensions in the air (at TAMA warehouse).

Scope of the work on June 5th and 6th

Check what kind of fixtures we still have Remind ourselves how to suspend mirrors DIscuss how to convert the PO-type suspension to the one with normal angle incidence. Discuss how we can improve TAMA suspensions to make it slightly more modern Preparations
