| * 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 measured another filter. * 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 worked on work platforms for the installation. * Hirata-san looked for 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. |
* Fabian took photos of the cleanroom in the ATC. * Hirata-san ordered wire for the BS. * Fabian weighed the masses that he'd been constructing in the cleanroom and found a 600 g discrepancy from the Inventor. * Hirata-san ordered a medium-capacity scale to help check the masses of the parts. |

| * Wires * Need to decide RM wire thickness and order BS and RM wires. Lead time is a few days from Nilaco. |

| * Feedthrough Adapters * Need large quantity of male and female D-Sub 9, IDC ribbon connectors - Takahashi-san is getting a quote. * Can we make SR wire breakers bigger? * Fukushima-san will start on machining test soon (as of 5/27). * Not enough crane height problem (Hirata, Saito) - no action since last week * Installation stuff * Crane scale - ordered * Work platforms - ordered * Ballast masses for payload * Initial batch received - ordered extra smaller ones to allow for adjustments. |
* Akutsu-san is working to get wide-mouth OSEMs * Longer cables for BF->PI and SF->PI. * Connectors RECEIVED, cables being made. * SR machining test ongoing. |
