Another Bottom Filter inspection.

With Hirata-san and Washimi-san.

Hirata-san and Washimi-san checked a couple of things I had checked before:

  • We locked the BF sides to the security structure.
  • Hirata-san and Washimi-san, one at the time, pulled the BF-IM suspension rod down and agreed it went down smoothly several milimeters.
  • Hirata-san and Washimi-san used the inspection mirrors to see the yoke-coil-magnet-actuator assembly underneath the BF. Nothing seemed to be touching.

Once we finished the released the IP and closed the vacuum chamber.
