* Type B Past Week Summary * Mark updated the BS circuit diagram [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600|D1503600]]: * Added information on the binary IO. * Renamed channels to conform to Okutomi-kun's new scheme. * Made the ADC/DAC channel assignment consistent and more logical. * Updated the stepper motor sections with info about the new driver chassis. * Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.) * Mark worked on schedule. * Mark updated the installation procedure with lessons learned from the last few weeks. * Mark downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board. |
* 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. |
