| * Type B Past Week Summary * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka: * Hung RM. * Did permanent routing of RM OSEM cables to IM. * Did temporary routing of RM OSEM in-vacuum cables to flange (4 channels). * Did semi-permanent routing of all OSEM external cables to satellite amps (10 channels) * Did temporary routing of RM OSEMs to PR2 rack (4 channels). * Took data with geophones connected but immobilized and then stored geophones in boxes. * Tested signals from first satellite amp getting to digital system. * Weighed mirror box. * Did fit check of flag holders for stub flags. Very minor adjustments will be needed. * Covered everything in preparation for modifications to clean booth roof (9/20-21). * Hirata-san: * Finished 3D CAD of SR2 and SR3 in tanks, with optical layout included. * Started 3D CAD for SRM. * Checked flag design. * Assembled a bottom filter (ongoing). * Cleaned maraging rods. * Type B ongoing issues * Longer term to-do list * Do Inventor assembly for SRx in chamber and on assembly frame (Hirata) - SR2/SR3 DONE, SRM ongoing. * Part "disk security" top has to be modified - screw positions do not match. * 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.)
