| * Fabian finished dummy BS assembly. * Mark and Tatsumi-san glued magnets into both types of BS optic flags, and discs into BS IM flags. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1815 |klog]] Two optic flags had to be redone because the magnets moved while the glue was drying. Hirata-san helped remove the magnets with acetone in the ultrasonic cleaner. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1818|klog]] * Tatsumi-san, Fabian and Mark took the dummy BS to Kashiwa and glued the flags and prisms. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1821|klog]] We will check status on Mon 6/13. * Hirata-san moved in another filter for testing (but didn't get to measure it). * Hirata-san washed a batch of parts. * Hirata-san modified the design of the parts of the assembly frame supporting the BF and SF to include bushings for smoother movement. * Hirata-san researched and ordered a crane scale for use at the site. (We decided the 500-kg version of the 200-kg one used at TAMA. It is the same price and has the same 100-g resolution for the first 250 kg.) * Hirata-san worked on making some guide parts for the PI installation (Misumi parts with minor additional machining from ATC). * We finalized a design for simple SS mirror parts for the dummy BS with Akutsu-san. They will be made by ATC. * Mark worked on list of items for purchase in FY2016 and on the schedule. * Fabian did more work on the IM assembly. It is nearly done and he will start on the RM next week. There were some issues with crimping connectors to wires for making pico adapter cables. |
* Mark and Fabian worked at Kamioka: * All the parts for the security structure were located. The clamp pieces for the IM are being taken back to Mitaka to have extra screw holes added. * The BS/PR2/SR2 area was cleaned and tidied to allow floor removal and assembly frame construction. * 21 "Type 1" cables (PI-Flange, Signal) and 15 "Type 5" cables (OSEM) were tested. They all passed. Sufficient tested "Type 2" cables (PI-Flange, Motor) were located in the PR3 area. * Hirata-san worked on the Inventor assembly, adding views (originally defined by Mark) of the different phases of construction. * Hirata-san shipped 7 SFs and some parts to Kamioka. * Hirata-san made assembly drawings of the damper rings and cable clamps for SR. * Hirata-san liaised with Mirapro about the frame assembly. |

| * Akutsu-san is working to get wide-mouth OSEMs * Longer cables for BF->PI and SF->PI. * Takahashi-san has ordered extra connectors (due any day) and will get a company to make the cables. |
