=== Type-Bp PR2 === This week we inspected and tightened the wires clapms in PR2. We followed the same procedure as in PR3, so I won't write any details here. * We removed the IRM side panels and measure the gaps in different places using thickness gauges: * Largest gap: 220 um close the wire, but smaller exactly where the wire is. * Smallest gap: (50 , 60 ) um. * We tightened the clamps according to the specification: 10 Nm for the weight holding ones and 2 Nm for the locating ones. * 10 out of 12 screws rotated by small amounts when tightened, however, * The two screws of the locating clamp at the +Y side were completely loose. * After we re-assembled and released the payload we realized it had a lot of negative pitch (I wrote positive in the klog, sorry) and at least one OSEM flag was touching. * We corrected the pitch with the picomotor. * We also moved the BF keystone close to nominal position with the fishing rod. * Then we corrected IM yaw. * We found picomotor cables and stepper motor cables disconnected, so we connected them. * By the end of today's work the IM seemed to be hanging free. * We tried to measure TFs, but it seems the actuation is not going through because of a problem in the real-time model. Miyo-kun and Ikeda-san will take a look. |
