| = 20180305 = * [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4349]] == Today's activities == Workers: Miyo, Akutsu * Restarted the cryocon. * Yokozawa-san reported it was strange on Sunday. * In short, restarting it did not help the situation very well. '''''No idea...''''' * Anyway EPICS can pick up the data from it. So far so ok. * Attached the sixth, and the last thermometer at the side pillar of the suspension. * The place is opened when the protectors were removed. So installed today. * The signal wires were connected to the cryocon, and now online. * Note that this thermometer uses all 75-ohm lines, different from the other ones. * Heat-anchored some electric wires to the IYC chamber. * One is the wires from the thermometer described above; Kimura-san said we don't need to care, but I can do so I did. * Another is fluffy wires; to fix them I just press. * '''[Ongoing]''' Need cares of water springs from anchor bolts for oplev pylons. * '''[Ongoing]''' Need to confirm what are the scratch lines made by the measurement by the KEK team last week. == Next plan == * Make heat connection upper and lower part of the suspension by Cu wires. * Complete the PS calibration. * Complete the calibration of the oplev; the arm length was reported by Simon, so.... * Complete the signal matrix. * Check the balance of the suspended WAB with some wires and sensors are attached. * Check how the damping would be now after the replacement of the damping magnets. * Check the reproducibility of the alignment of the suspension among several modes. * Check heights of several points. * Take care of water spring?? == Wanted! == * Two burndy connectors, vacuum compatible. * '''''Stages outside the chamber''''' to ease wiping our legs. * Good '''''rail(?)''''' to move the WAB suspension in the cryostat in the main beam direction. * '''''Chain block?''''' to support the load in the chamber. * A clock to know the time easily. * M6 screw set. |
