| ==== Report for week of 3/19 ==== * Fujii-kun successfully assembled and tested a geophone pod (klogs 4492, 4508). * Hirata-san set up the dummy BS to soak off the sapphire prisms. (In process) * Shoda-san, Hirata-san and Enzo finished the assembly of 12 OSEMs. We still need to measure the maximum output (In process) * We will send the OSEMs to Kamioka today. |
==== 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 3/26 ==== * Tanioka-kun joins. * Mark vacation. * Shoda-san at Mitaka * Others at Kamioka * -- * Lay SR3 in-air cabling (Enzo++). * Finish tuning of BFs (Hirata-san++). * SF check (Hirata-san++). * Check load capacity. * Check fit of caps. * Add cable clamps to bases. * Add cable clamps and Cu segments to caps (only if they fit well). * Cable LVDTs and steppers. ==== Plan for week of 4/2 ==== * Mark at Mitaka Mon, Kamioka from Tue. * Shoda-san at Mitaka * Others at Kamioka * -- * Glue SR3 (if available) * Build 2xIM, 2xIRM (if parts available - due 3/30) ==== Plan for week of 4/9 ==== * Shoda-san at Mitaka * Others at Kamioka * -- * Finish IMs and IRMs * Build 1xRM ==== Plan for week of 4/16 ==== * Start SR3 Hang? ==== Plan for week of 4/23 ==== * F0 blade prototype test ==== Plan for week of 4/30 ==== * Golden Week! |
==== 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.) * |

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
