| * Fabian took photos of the cleanroom in the ATC. * Hirata-san ordered wire for the BS. * Fabian weighed the masses that he'd been constructing in the cleanroom and found a 600 g discrepancy from the Inventor. * Hirata-san ordered a medium-capacity scale to help check the masses of the parts. |
* Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka: * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]]) * Hung dummy optic and set pitch. * Prepared RM. * Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables. * Decided position of BS rack with Miyakawa-san. * 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. |

- Type B Past Week Summary
- Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka:
Calculated BS pitch correction (JGW-T1605630)
- Hung dummy optic and set pitch.
- Prepared RM.
- Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables.
- Decided position of BS rack with Miyakawa-san.
- 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.
