Schedule
- 12th Jan- (2 weeks) Disassembling, Washing, and transportation
- 25th Jan - (2 weeks) Assembling and Test Hanging with an Al dummy mirror
- 7th Feb- (1 week) coil winding, measurement of transfer function, transportation to the End area and installation test
- 15th Feb- (1 week)installation
Disassembling at ATC Mitaka [Ohishi] (12th-19th Jan.)
- Two nuts stuck. Hirata-san removed them.
- A Cu screw stuck. Hirata-san removed it.
Washing and transportation to Kamioka [Hirata-san]
- The ultra sonic washer at ATC was broken on 20th Jan. A new washer was ordered on 22th(Fri) and arrived at Mitaka on 25th(Mon).
- Eight screws for adjusting the IM holding plate was dirty. Takahashi-san ordered similar screws.
New parts
- coil bobbin [Takahashi-san]
- coil winding [Kuwahara-san, and Ushiba-san]
- coil wires from the bobbin to Dsub connector were too short(20cm). The length 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 Feb.
- 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
Assembling [Tomaru, Ohishi, Yamamoto]
- On 21th, suspension frame, security frame, xy stages completed
Hanging
- Hanging jig preparation
Transfer Function Measurement
Transportation to the End
