Setup of BF with the released cryo-payload

[Takahashi, Sato, Horiuchi + CRY]

The cryo-payload was released. We went to setup of BF.

  1. Checked the height of F0 keyston. The release sensor indicated only one of three for the F1.
  2. The cryo-payload was released.
  3. Released the BF keystone.
  4. Set the height of BF to 68mm with the bottom stoppers.
  5. The height of keystone was at the lower limit. This means overload. It was possible to pull up the keystone by our hand.
  6. Observed the inside of BF with a fiber scope. The position of FR, the FR blades, the addtional blades, and the blade anchor look fine. The secondary coil was pushed by the bar for yaw FR.
  7. Lifted up and fixed the keystone with a long nut at 1050 count corresponding to 68.5mm in height.
