==== Report for week of 1/29 ==== * Mark made two sets of in-air pico splitter cables (each with a triple for IM and a double for BF) for SR2 and SR3. * Fabian, Hirata-san and Kozu-kun worked on cabling and testing the IM pitch/roll/yaw picos, the BF FR and the BF LVDT. The LVDT connections were initially unreliable and Hirata-san had to redo the pins on the coil wires. * Fabian installed ballast masses in the BF. * Mark worked on schedule. * Mark did inventory of the stepper motor drivers (many were not accounted for on the wiki and/or JGWDoc and one is missing) and reserved two for SR3. ==== Plan for week of 2/13 ==== * No work Monday (建国記念の日の振替休日) * Enzo on vacation * Hirata-san at Mitaka Tue, Wed (to receive and wash parts). * Shoda-san at Mitaka * All others at Kamioka. * - * Build IRM around IM. * Cable/test/adjust IM OSEMs. * Do TFs from IM OSEMs to IM OSEMs, OL pitch/yaw. ==== Plan for week of 2/19 ==== * Enzo back from Tuesday. * Shoda-san at Mitaka * All others at Kamioka. * - * Lift BF/... section and check total mass and balance. * Cable and test BF picos. * Add section of SS up to SF ring. * Bring in SF. * Hook BF/... section. * Route cables up to under SF. * Check/adjust total mass of BF/... section. |
==== Report for week of 2/19 ==== * We did TFs from the IM OSEMs. * We secured the cables inside the BF, added the cap and anchored the cables from below the BF to the cap. * We lifted the BF/... section with the load gauge adapter and measured the weight, which was about as expected. * Based on the measured weight, Fabian prepared an 800 g set of masses for the top of the BF. * We added the AF crossbars and the section of the SS below the SF and craned in the SF. * We installed the SF-BF rod and flying saucer and suspended the BF/... section. With the 800 g placed temporarily on the BF, the SF keystone floated at about mid-range. |

Report for week of 2/19
- We did TFs from the IM OSEMs.
- We secured the cables inside the BF, added the cap and anchored the cables from below the BF to the cap.
- We lifted the BF/... section with the load gauge adapter and measured the weight, which was about as expected.
- Based on the measured weight, Fabian prepared an 800 g set of masses for the top of the BF.
- We added the AF crossbars and the section of the SS below the SF and craned in the SF.
- We installed the SF-BF rod and flying saucer and suspended the BF/... section. With the 800 g placed temporarily on the BF, the SF keystone floated at about mid-range.
