| At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun, Kozu-kun): * We craned out the SF temporarily and retrieved the lost PEEK cable clamp collet from the BF. * We installed the BF. * We routed cables from the BF via the hex cable clamp to the SF level. * We adjusted the BF trim mass for pitch, roll and vertical, and got the IRM hanging symmetrically around the IM. * We adjusted all the IRM OSEMs laterally and in/out. * We calibrated the SF LVDT and tested the SF FR stepper. * We suspended the SF/... section and weighed it but found the old 7-mm maraging rod adapter did not hold it at the center, so we chad to lift it with slings and could not accurately trim it for pitch/roll. * We craned in the PI with the SF damper ring hanging from it. * We suspended the SF successfully from the PI and unlocked the F0 keystone to check the mass budget. We needed about 1.5 kg extra, which is about right. * However we had to leave out the F0-SF hex cable clamp because of a bad thread on the inside of the cap. Hirata-san will make a new cap by enlarging the 7-mm hole in an old cap to 8 mm. |
At Kamioka (Mark, Fabian, Enzo, Hirata-san): * Hirata-san did an inventory of SR and other parts at Kamioka. * 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). |
