I did for Type-B as below, ・modified parts list and screw list for Payload. ・sent lists to i-ject and asked for quotes. (But we need to send latest list again.) ・made drawings for some jigs and some parts for payload. |

For PR ・searched glueing 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. |
==== Plan for week of 3/19 ==== * Mark at LVC meeting * All others at Mitaka * Make two sets of IM OSEMs * Make last in-air pico adapter cable * Make three in-air stepper splitter cables for SR2, SR3 and SRM. * Set up Dummy BS prism removal. |

For others ・washed IMMT plate and send them to Kamioka. |

Succinctly, it is as follows: 1. Mechanical design: a. Pull down system to fix the power recycling IM to the EQ stop. b. EQ stop for the BS recoil mass. 2. Checked assembly PR/SR drawings. There were few corrections/changes. 3. Checked fastener list. There were few corrections/changes. 4. Checked component list for the manufacture order. There were few corrections/changes. 5. I helped in searching for the PR mirror box missing pieces at Mitaka. Regards, Fabian }}} |
