* 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. |
* Mark and Fabian did a huge cleanup of the SR2 area and prepared a workspace for assembling the IM. * Fabian did a stocktake of the screws for the SR. * We have all we need for the IM, except one type that can be added after the rest of the IP is assembled. * We have most of what we need for the rest of the payload, and Hirata-san has ordered the others. * Hirata-san worked on SR procurement: * Suspension wire * SR additional parts (compensation masses, clamps etc) * Regular, SDC and BUMAX screws. * Additional machining on the BS sapphire prism jig to allow it to be used on the PR/SR mirror box. * LBB blade design. * Enzo and Kozu-kun (with help from Fujii-kun) worked on export from SUMCON to Matlab, and on filter design. ==== Plan for week of 11/20 ==== * Holiday on Thu 3/23 * All at Mitaka. * SR procurement, planning (Mark, Hirata-san) * SR mass budget (Fabian) * BS modeling filter design (Enzo, Kozu-kun) ==== Plan for week of 11/27 ==== * Fabian at commissioning workshop * Hirata-san at Kamioka to work with Mirapro on SRM LBB installation. * All others at Kamioka to start SR2 assembly. |
