| * Periscope install * Equip picomoters to the mirror * Wall between duct and modules * Ordered. Will arrive Kamioka on 9/10. * Set duct and wall. * Green laser preparation * Power supplies are OK. * Waiting for new post. * Rx module alignment * TCam has to come back. * PC has to be re-installed. * AOM current * Sometimes over 0.5 V ? * Stray light * Put dumpers * Borrowing 2 from Toyama univ. They has to be returned on 9/19 or 20. * WSK measurement * Alignment of the last 2 mirrors (Accidentally moved) * Modification is required from LIGO's procedure. * Code for WSK measurement analysis * To be delivered on 9/19 or 20. * May have to prepare voltage calibrator to calibrate readout by DGS. * DAC noise problem * With DAC cable, very large noise and offset are observed.
