| * Type B * Hirata-san finished the design of the trolley system (including adapter plates for the mirror box). * Mirapro reported that rails for the trolley system had a long lead time, so we decided to order them separately. * IM and BS flags were ordered. * Tatsumi-san ordered the prism gluing jig parts for the mirror box. * Hirata-san measured another SF. * Mark worked on the assembly procedure. * Fabian worked on the Mathematica/Matlab model of the BS. |
* Type B Past Week Summary * Mark and Hirata-san worked at Kamioka, with valuable help from Enzo (on loan from Type Bp team). * We got all the adapter cables for the BF made (Hirata-san did some work on Monday at Mitaka). * We installed the extension for the BF yaw pico on the IM pico adapter cable. * We got all the in-vacuum and in-air cabling for the IM OSEMs done. * We tried to install the stepper and LVDT adapter cables but realized we didn't have enough information on which wires was which. (We later tracked this info down but did not have time to do anything with it - we would have needed to do the rest of the in-vacuum and in-air cabling and set up the stepper motor and LVDT drivers, so we concentrated on the OSEMs.) * We plugged in the IM OSEMs, set gains and offsets, and did a noise test (analysis and klog pending). * We mounted the OSEMs on the IRM and routed the cabling neatly. * We released the suspension. * We adjusted the OSEM mounting plates to center the OSEMs on the flags. * We adjusted the OSEMs in/out to midrange. * The suspension is now ready for OSEM-OSEM TFs! |
