| * 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 ongoing issues * Longer cables for BF->PI and SF->PI - RECEIVED |
* Fabian, Mark and Liu-kun did BS installation at Kamioka: * Built up the security structure to the ring below the BF. * Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF. * Craned in the BF. * Took TFs from L and P actuation at the RM to all DOFs at the BS. (Y actuation still to be done.) * Hirata-san: * Made 3D models of (revised) stub flag gluing jigs. * (For other groups) * Assembled two BFs. * Made drawings of PRM inner frame. * Mark checked lots of drawings by Hirata-san. * Mark worked on schedule. * Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors were completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which makes everything work. |

- Built up the security structure to the ring below the BF.
- Adjusted the crossbeams below the BF and installed the jacks and pushrods to support the BF.
- Craned in the BF.
- Took TFs from L and P actuation at the RM to all DOFs at the BS. (Y actuation still to be done.)
- Hirata-san:
- Made 3D models of (revised) stub flag gluing jigs.
- (For other groups)
- Assembled two BFs.
- Made drawings of PRM inner frame.
- Mark checked lots of drawings by Hirata-san.
- Mark worked on schedule.
- Mark added the DIO card to a draft of the BS electronics diagram, D1503600. At first it appeared that the pinouts of the LPCD DIO connectors were completely incompatible with the DIO card cables, but it turns out (according to Miyakawa) that the LPCD chassis has a secret interface board (JGW-D1504332) not shown in the chassis drawing which makes everything work.
