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.
- 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.
- Hirata-san
- Fabian measured the gain of the ADC system (homework from the Commissioning Workshop).
