Report for week of 1/29

  • We moved the top filter intended for SR2 (#1) into the SR3 cleanbooth.
  • Unfortunately we noticed one of the blades had many small X-shaped stress fractures on the top surface (klog 4058).

  • We moved the top filter entered for SR3 (#3) into the SRM cleanbooth and inspected the blades. Two had one smallish stress fracture each and one had a huge fracture and looks close to failing (klog 4061).

  • We referred the BS OL.
  • We removed the BS tank lid and inspected the BS top filter blades. They seemed fine (klog 4073).

  • Hirata-san received and washed some ferromagnetic disks for IM flags and other small parts.
  • Hirata-san moved the BF with the tilted keystone (#1) out of the cleanbooth in preparation for rebuilding.
