| * Top rid of PR2 and PR3 vacuum tank were fixed * Note that the feedthrough flanges are not closed yet. * During the fixing, we accidentally moved the injection beam of the Oplev. Alignment was lost. * We need to re-align the main beam. So far, we are planning to do it in the week of the commissioning WS. * PR mirror position was measured by FARO. * The position of the mirror is off from the design by: * PR2: (-9.4, +0.5, -6.4) * PR3: (-3.5, -0.5, -4.9) * PRM: (**, 4.6, -1.5) Note: PRM is fixed Note that these values are relative to the side flange of the vacuum tank at the HR side. x is the norm of the flange surface, and z is the norm of optical bench. |
