At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun, Kozu-kun): * We solved the problem with the OSEMs: cables had been plugged into the LED current monitor outputs, not the PD outputs. * We solved a problem with the real-time model freezing which turned out to be the IO chassis having lost power. * We took some mass off the IM to allow for the weight of the cables, and readjusted it in pitch and roll. * We aligned the IM |
At Kamioka (Mark, Fabian, Enzo, Hirata-san): * Hirata-san published his inventory of SR parts on Dropbox. * Mark and Enzo finalized the geometry matrices for the IP, entered them in MEDM and updated the safe.snap. * Mark, Enzo and Fabian worked with Izumi-san et al. to align the BS. We got the +Y beam fairly close to aligned (to the second gate valve, near IY). |
