| * There were multiple issues with the dummy BS flag/prism gluing [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=1830 |klog]]. The sapphire prisms will need to be removed and reapplied. Hirose-san is going to organize this. He is trying the cup that had been made for the PR2 on the actual PR2. It works to confine the acetone, and we will see shortly how much soaking is required to get a prism off. We will then see if a new cup is needed for the BS (considering the different radius). * Hirata-san added the optical layout information to the BS Inventor assembly. He requested tank information from Mirapro so he can continue to do SR2/3/M. * Hirata-san worked on the crane height problem with Saito-sensei. They concluded that craning in the suspension is possible but will require not just the vacuum tank lid but the ≈30 cm section of tank below it to be removed. * Hirata-san liaised with Nakamura-san of Mirapro. Mirapro could start assembling the frame in the first week of July. * Fabian finished the IM assembly and started on the IRM and RM. Some of the IRM panels had been improperly wrapped and will be re-cleaned. The MPC (multi-purpose cube) on the RM will need some rework. * Mark did a top level schedule. * Mark released a draft (about half-finished) of [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| JGW-E1504235 - BS Installation Procedure]]. * Mark updated [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600| JGW-D1503600 - BS Suspension Cabling]] with a better arrangement for the IM and BF pico motor cables, as well as various other minor fixes. * Mark organized a review for Thursday 6/16. |
* 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. * Hirata-san ordered a medium-capacity scale to weigh the masses of the individual parts more precisely. * 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 and a second trip. * Shoda-san took a suitable segment of geophone noise data for analysis. Fabian will track down the calibration factors. |
