| * Type B Past Week Summary - weeks of 8/22 and 8/29 * Fabian, Mark, Zhao-kun and Yokogawa-kun did BS installation at Kamioka: * Weighed the BF, SF and dummy BS (in mirror box). * Moved the geophones onto the optical table, clamped them down and took another time series for analysis. * Aligned the IM, installed the extra trim masses, tested the picos and weighed the whole assembly. * Placed vacuum flanges and cleaned D-Sub cables ready for routing to the rack. * Realigned and immobilized the optical table (which had been bumped). * Made safety improvements on the second floor (new safety rail, new arrangement of floor pieces, caution tape around holes) * Suspended the dummy BS. Currently however it is not hanging correctly, but is off in the +Y direction by several mm relative to the mirror box. * We set up the BS OL, using one of the wheeled chests of drawers as a base and using the OL breadboard from the PR2 assembly frame. * Hirata-san made a 3D assembly model for SR2 and added the optical design. * Hirata-san worked with Uchiyama-san to solve the 90° rotation problem. It turns out the "box" part with the pistons can be rotated, so we can build the SR2 according to the original design. * Hirata-san investigated the puzzle of the BF-IM maraging rods, where the 2D drawings and 3D CAD do not agree. Fortunately the actual parts seem to agree with the 3D CAD. * Hirata-san washed 3 OSEMs (last of initial 10 for BS) and parts for two BFs (for Type A). He moved the BF parts into the clean room and will assemble them with ATC staff from next Wednesday 9/7. * Type B ongoing issues * Longer cables for BF->PI and SF->PI - RECEIVED * Longer term to-do list * Decide position of BS rack - DONE * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE. * Write more of payload assembly procedure (Fabian) - ONGOING * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING * Lower breadboard installation to be incorporated into the procedure document. * Work on BS simulation (Fabian) * Do BS Simulink model (Mark, Kokeyama) * Do 2D drawings of SR2 parts (Hirata) * Redesign SRx IM wire clamps for larger prisms, remachined RMs * Order SRM/PRM parts (Hirata/Shoda) * Order SRx fasteners (Hirata) |
* Activity report for weeks of 12/26 and 1/2 |

| * Hirata-san: * Modified parts list and screw list for payload. * Sent lists to i-ject and asked for preliminary quotes. * Made drawings for some jigs (PR hold-down jig) and some parts for payload (PR/SR wire clamps with disposable jaw pieces - improved version with disposable pieces in both primary and secondary clamps). * For Type Bp: * Searched for PR gluing jigs. * Washed and assembled recoilmass base for mirror hanging jigs, and sent them to Kamioka. * Washed additional masses for IM and sent them to Kamioka. * For others: * Washed IMMT plate and sent them to Kamioka. * Fabian * Designed a pull down system to fix the PR IM to the EQ stop (similar to the SR one). * Worked on design of the SR assembly frame. As hoped, the SR version can be almost identical to the BS version. * Worked on design of additional trim mass (≈18 kg) for the BS BF. * Checked assembly PR/SR drawings. There were a few corrections/changes. * Checked fastener list. There were few corrections/changes. * Checked component list for the manufacture order. There were few corrections/changes. * Helped in searching for the PR gluing jigs. * Mark * Started design of SR assembly frame (but then passed it to Fabian). * Worked on task lists and schedule. * Plan for 1/10-13 * Mark and Fabian at Kamioka: * Finish rebalance of IM * Reinstall IRM, adjust OSEMs * Replace broken Type 3 cable. * Do TFs from IRM OSEMs to IRM and IM OSEMs. * Cable up and test BF LVDT and fishing rod (time permitting). * Disconnect BF and ship back to Mitaka (time permitting). * Hirata-san: * More SR procurement. |
