| * Hanged RM * We inserted the RM around the mirror, and hanged the RM. * Since the number of the RM ballast masses is wrong, we asked ATC and MESCO to machine the thinner ballast masses. They were delivered almost at the same time. Now we have 2 spare ballast masses. * The EQ stop below the RM was assembled. * DGS/Circuits preparation * DGS people added one more field rack for PRM, but the length of the cables between the AA/AI chassis and the IO chassis was too short to set the AA/AI chassis inside the PRM field rack. We did re-cabling. * Top plate and Traverser were assembled and placed next to the PR3 chamber. We have silver coated screws to fix the Traverser on the Top plate, but they do not fit well. Waiting for the SDC screws. * BF bearing was replaced by Mark. Thanks! * BF LVDT calibration is ongoing. |
