==== Past week report ==== At Kamioka (Mark, Fabian, Enzo, Hirata-san): * Hirata-san published his inventory of SR parts on Dropbox. * Mark and Enzo finalized the geometry matrices for the IP, entered them in MEDM and updated the safe.snap. * Mark, Enzo and Fabian worked with Izumi-san et al. to align the BS. We got the +Y beam fairly close to aligned (to the second gate valve, near IY). |
==== 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 [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4058|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 [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4061|4061]]). * We referred the BS OL. * We removed the BS tank lid and inspected the BS top filter blades. They seemed fine (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4073|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. * Hirata-san placed the second order for payload parts, and an order for remachining of nuts for cable clamps on rods. * Fabian measured the gain of the ADC system (homework from the Commissioning Workshop). ==== Plan for week of 2/5 ==== Enzo on vacation; all others at Kamioka. * Make in-air pico adapter cables. * Calibrate LVDT. * Test IM picos and BF yaw pico. * Test FR. * Install ballast mass in BF. * Build IRM around IM. * Cable/test/adjust IM OSEMs. * Time permitting, do TFs from IM OSEMs to themselves and to optical sensor. |

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.
- Hirata-san placed the second order for payload parts, and an order for remachining of nuts for cable clamps on rods.
- Fabian measured the gain of the ADC system (homework from the Commissioning Workshop).
