- Hanging and Installation Procedure:
- Inside the IFI chamber, there already is set large IFI;
- it is so crowded and seems to be difficult installing IMMT suspension from the side flange.
- We are planning to install IMMT2 from the top flange.
- Need discussion with Hirose-san about cleanliness control.
- IMMTs are not on the center line where cranes move.
- So perhaps we need to move IMMT by hand after we install it from the top flange.
- Inside the IFI chamber, there already is set large IFI;
- Place for hanging:
- Unfortunately I could not have find breadboard legs.
- Ask Kawamura-san if I can use small optical table that was used at MC recently replaced with larger optical bench.
- Cables:
- For initial alignment, planned in January, I think only Pico-motors will be necessary.
- (Coils will not be used for initial alignment.)
- There already cables used when it was used for iKAGRA ETMs.
- Check the place where cables are now.
- For initial alignment, planned in January, I think only Pico-motors will be necessary.
