| * Type B Past Week Summary * 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 * Longer term to-do list * Decide position of BS rack - DONE * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE. * Write more of payload assembly procedure (Fabian) - ONGOING * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING * Lower breadboard installation to be incorporated into the procedure document. * Work on BS simulation (Fabian) * Do BS Simulink model (Mark, Kokeyama) * Do 2D drawings of SR2 parts (Hirata) * Redesign SRx IM wire clamps for larger prisms, remachined RMs * Order SRM/PRM parts (Hirata/Shoda) * Order SRx fasteners (Hirata) |
=== Type B (Mark) === ==== Report for weeks of 5/14, 5/21 ==== * We weighted the IM/... section of the SR3. * We set up for the F0 blade prototype test. * Takahashi-san characterized the F0 prototype blades, and ordered final blades based on the BS and SR mass budgets. * Hirata-san characterized the LBB blades and identified three sets with blades of similar strength, plus two weaker ones. However he realized that M12x50 Bumax screws for the blade sets had not been ordered, so he got a new quote and ordered them for delivery 6/11. * Mirapro installed the mushroom section of the SRM tank. * We craned in the BF and cabled and tested the yaw pico, the FR stepper and the LVDT. * We hung the IM/... section from the BF, removed ≈200 g of trim mass and rearranged the rest to get the desired height, pitch and roll. * We added the sides of the IRM and the IM OSEMs, cabled the OSEMs, and adjusted everything to get good lateral and in/out alignment of the OSEMs. * Enzo did TFs using the IM OSEMs and the BF LVDT. * Hirata-san organized getting the LBB damper rings into the SR3 tank. He joined the halves of the Cu and magnet rings and got them ready for craning (which will happen later when we have rebuilt the SR3 IP and have somewhere to park the lid of the vacuum chamber). However he encountered a problem with the top ring: one of the screw holes in the top of the tank is not fully threaded, so one of the pillars supporting the top ring cannot be attached. He is considering various options. * Hirata-san and Kozu-kun made rod assemblies for the LBB damper rings. * Enzo made a batch of flipping and non-flipping feedthrough adapters. * Yamamoto-san connected up the SRM rack. |

Type B (Mark)
Report for weeks of 5/14, 5/21
- We weighted the IM/... section of the SR3.
- We set up for the F0 blade prototype test.
- Takahashi-san characterized the F0 prototype blades, and ordered final blades based on the BS and SR mass budgets.
- Hirata-san characterized the LBB blades and identified three sets with blades of similar strength, plus two weaker ones. However he realized that M12x50 Bumax screws for the blade sets had not been ordered, so he got a new quote and ordered them for delivery 6/11.
- Mirapro installed the mushroom section of the SRM tank.
- We craned in the BF and cabled and tested the yaw pico, the FR stepper and the LVDT.
- We hung the IM/... section from the BF, removed ≈200 g of trim mass and rearranged the rest to get the desired height, pitch and roll.
- We added the sides of the IRM and the IM OSEMs, cabled the OSEMs, and adjusted everything to get good lateral and in/out alignment of the OSEMs.
- Enzo did TFs using the IM OSEMs and the BF LVDT.
- Hirata-san organized getting the LBB damper rings into the SR3 tank. He joined the halves of the Cu and magnet rings and got them ready for craning (which will happen later when we have rebuilt the SR3 IP and have somewhere to park the lid of the vacuum chamber). However he encountered a problem with the top ring: one of the screw holes in the top of the tank is not fully threaded, so one of the pillars supporting the top ring cannot be attached. He is considering various options.
- Hirata-san and Kozu-kun made rod assemblies for the LBB damper rings.
- Enzo made a batch of flipping and non-flipping feedthrough adapters.
- Yamamoto-san connected up the SRM rack.
Plan for week of 5/28
- Mark, Enzo at Kamioka Mon-Fri.
- Hirata-san at Kamioka Tue-Fri. (Mon is monthly Mitaka day.)
- Kozu-kun at Kamioka Mon only. (Rest of week is job interviews.)
- TBD.
Plan for week of 6/4
- Mark, Enzo, Hirata-san, Kozu-kun at Kamioka Tue-Fri. (Mon is NAOJ medical checkup.)
