- 8 screws for adjusting the IM holding plate was dirty
- Solution: order new screws (by Takahashi-san)
New parts
- coil bobbin [Takahashi-san]
- coil winding [students of Ando-lab]
- coil wires from the bobbin to Dsub connector were too short(20cm). The length of Must be 40cm or more.
- At the end of coil wires, D-sub pins are swaged. We have run short of pins and waiting for delivery on 29th.
- Peeling off the coating of wires longer than the length of those pins make the wire broken easily.
- D-sub fixture plates [Takahashi-san]
- M3 holes were drilled to phi3.2 holes.
- mirror container [Tatsumi-san]
- magnets for dummy mirror (4 ; 2-phi-L-5mm Nd magnets) [Tomaru, Yamamoto]
- some screws in replace with Cu screws [Ohishi] [problem] replaced all Cu screws to stainless. Magnetism problem was indicated.
pico-motors and PZTs
- We have 4 pico-motors except for x-axis (the direction of the light ) y, z, pitch, yaw
coil driver
- We use KAGRA coil driver; we need to cheek its performance.
cables
