* Type B Past Week Summary, weeks of 9/19 and 9/26 * Fabian, Mark and Liu-kun did BS installation at Kamioka: * Connected the DIO card to the LPCD. (Simulink model changes will be needed to make use of it.) * Took TF data from the TM-H1 coil output to the voltage and current monitors and found that the response was approximately flat. * Used the 90° prism and the optical lever to set the pitch of the RM to match the dummy BS. * Removed the RM trolley and added the bottom section of the security structure. * Lifted the IM/RM/BS with the load gauge adapter and load gauge and measured its mass. * Hirata-san: * Modified drawing of maraging rods for BS [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5706| D1605706]] * Made 3D models of stub flag gluing jigs. * Made 3D models and 2D drawing of BS BF-IM hexagon cable clamp assembly and cone parts.

Type B (Mark)
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.
- 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).
Plan for week of 1/29
