| * 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 to help decide whether it is a good place to assemble PIs for Type A/B. * Hirata-san ordered and received wire for the BS and RM (will be cleaned 7/19). * Hirata-san received remachined locking parts for the IM (will be cleaned 7/19). * Hirata-san ordered additional Misumi parts to be used with the IM locking parts. * Fabian and Hirata-san weighed the masses that they've been constructing in the cleanroom and found a 600 g discrepancy from the Inventor (too light) for the IM. Although the density assumed in the Inventor agrees with spec sheet values, it doesn't match the parts. Adjusting the density to match a few key parts reduces the discrepancy to 60 g. More investigation is planned. * Hirata-san ordered a medium-capacity scale to weigh the individual parts more precisely and help locate the discrepancy. * Hirata-san organized to do a fit/function test of the BS winches and training session with Ikenoue-san of ATC on 7/25. * Hirose-san and his team successfully removed the misglued prisms from the dummy BS. * Fabian travelled to Kashiwa and removed most of the glue from the face of the dummy BS (where the flags had been). There is still some adhesive remaining on both the face and barrel, which will require more work in a second trip. * Shoda-san took a suitable segment of geophone noise data for analysis. Fabian will track down the calibration factors. * Hirata-san worked on 2D drawings for the PI cable clamps and the magnetic damper for the lower breadboard. * Hirata-san worked on the 3D assembly for SR2. |

| * 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 - quote received * Work platforms - quote received * 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. |
