Hirata-san:
- Did drawings of SR damper.
Mark, Fabian, Enzo and Hirata-san (at Kamioka):
- Took the end plate off the IM to get access to the pitch/roll picos.
- Found the pitch pico was unreliable and replaced it.
- Found the springs were not stiff enough, and immobilized 7 turns at the end of each with Cu wire to make them stiffer.
- Reassembled and rebalanced the IM.
- Reassembled and adjusted the IRM.
- Discovered that the transverse offset between IRM and IM could be corrected by adjusting the roll of the BF.
- Adjusted IM OSEMs to half-way.
- Made and installed a new pair of wires for the BF yaw pico on the IM pico adapter (Hirata-san).
- Installed an improved LVDT cable made by Hirata-san.
- Made and hung posters for the Elites meeting visitors.
