| * Prepared RM. * Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables. |
* Prepared RM for hanging (adding OSEMs etc). One OSEM (#24) had wobbly leads and was brought back to Mitaka for rework. * Placed vacuum feedthroughs on assembly frame and cleaned initial batch (4) of D-Sub cables. |

| * Measured maraging rods. * 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. |
* Measured various maraging rods and the rod holders on the SF. * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety. * Hirata-san: * Made new 3D models of the maraging rods for PRx and SRx * Made new collet design for PRx and SRx (3D and 2D). * Made new IM flag design for PRx and SRx (3D and 2D). * Washed lots of Type A BF parts and OSEM parts. * Cleaned the BS BF-IM maraging rod and organized the rest of the stock of rods. * Measured some BF part dimensions. * Pre-assembled parts for BFs. |
