== Initial Preparation ==

  • [Done] OMC #002 placement
  • [Done] OMC #002 locking
  • Details OMC ELOG 414

== Measurements ==

  • [Done] Transmission / Power budget before FirstContact OMC ELOG 416
  • [Done] Transmission / Power budget after FirstContact OMC ELOG 417
  • [Done] Backscatter measurement with a new deflection optics
    • [Done] Optics bonding done waiting for cure OMC ELOG 420 -> Returned the bond to Madeline OMC ELOG 424
    • [Done] Backscatter measurement
      • Measurement: 0.6 ppm OMC ELOG 422
      • (Transmission is 10~60mW. If the backscatter is the order of 1ppm or less, we expect the light level is ~10nW. Can we really detect it? How? ... OK... last time the measurement has been done with the stick PD type powermeter with baffles and the room light turned off (OMC ELOG 209). So it's not totally crazy.)
