=== 2019/2/4(Mon.) === === Weekend === === Schedule === * Current status as of 1/22: IR and Green reached X end PD. * --(1/22: Surface inspection for PR mirrors.)-- Cleaning will be done after 1/31. * --(1/23: Surface inspection for SR mirrors.)-- * --(1/24-25: Cleaning HR of SR3, SRM.)-- * --(1/23: BS is aligned to Y-end PD by IR.)-- * --(1/27: ITMY is aligned to REFL by IR.)-- * --(1/27: ITMX is aligned to REFL by IR.)-- * --(1/27: Beam position of IR at SR3 is confirmed how far from the center.)-- * --(1/28-29: SR3 is aligned to SR2 center by IR.)-- * --(1/28: Alignment of SR2 -> SRM by IR.)-- * --(1/29: Green beam is injected from SR2 AR surface to Y end PD.)-- * --(1/31: Removing bellows at PR and SR area.)-- * --(1/31-2/1: Cleaning HR of PR3 and HR, AR of SR2)-- * 2/4-8: SRM -> OMMT by IR -> OMMT -> OSTM by IR, OSTM -> OMC by IR * 2/4-8: Alignment of ETMY -> POS by Green * 2/12-15: Closing door for central area, pumping down * needs drift monitor for VIS ==== Note ==== * Report klog, and gokagra ML if urgent things. ==== Report of work ==== *MIR: * SRM: It seems to be that mirror rotated 180degree. * It is still not perfectly sure actually SRM was rotated, it could be design itself or mistake of position of something downstream. * In any case, we need to correct something. * Type B team will look at probably today and tomorrow. * COMM: Needs some alignment downstream SRM due to the mystery above. * IR did not hit SR2 center. It will be checked. * IOO: For high power test, we could inject less 10W due to saturation of FSS. * MIR: HR surface of EXMX has some dusts. We should discuss whether we should clean or we should leave it with some information of other test masses. ==== Work plan ====
