| * 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 wiped one set each of wires for the BS and RM (addition sets pending). * Hirata-san washed remachined locking parts for the IM and screws for jacks. * Hirata-san liaised with Ikenoue-san of ATC to get new winch parts designed for the new wire thicknesses. Ikenoue-san provided updated designs for checking. * Hirata-san worked on the Inventor 3D assembly of the SR2. * The scale for checking the masses of the IM parts was received. * Fabian and Hirata-san identified an issue with the lock screws between the IM and IRM. The screws were slightly too large, and correcting the size with a die caused large flakes of the black coating to come off. (These screws were ordered before the current screw policy was instituted.) Hirata-san will order better screws from Misumi and have additional machining done on them. * Fabian tracked down the calibration factors for the geophones and generated a calibrated plot. |
* Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka: * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]]) * Hung dummy optic and set pitch. * Prepared RM. * Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables. * Decided position of BS rack with Miyakawa-san. * Measured maraging rods. * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety. * Hirata-san: * Made new 3D models of the maraging rods for PRx and SRx * Made new collet design for PRx and SRx. * Made new IM flag design for PRx and SRx. * Washed lots of Type A BF parts and OSEM parts. * Measure some BF part dimensions. * Pre-assembled parts for BFs. |
