==== Report for week of 4/9 ==== * We packed away the SRM SF and BF. * After several failed attempts with one secondary prism, Mark finished the SR3 prism/magnet gluing. * Tanioka-kun built two IRMs (less OSEMs). * Enzo built an RM. * Kozu-kun and Enzo calibrated one set of 6 IM OSEMs for SR3. (6 OSEMs for SRM remain to be done.) * Hirata-san aligned the assembly frame, installed the interface bars and IM ring, and installed the IM. |
==== Report for week of 7/17 ==== * We checked the polarity of the IP LVDTs and flipped coil connections to get the standard arrangement. * We debugged an issue where one of the LVDT actuators had half the magnets in backwards resulting in no force. * We calibrated all the PI LVDTs. * We set the SF damper ring gap. * We prepped the suspension for craning, moved it into the tank and hooked the LBB damper ring rods. * Type A merged the SRM F0 with the correct IP, and we moved it out of the way (to the second floor behind the SRM tank). * We installed more cable clamps on the SR2 PI. |
