Abstract:
We have measured position of iKAGRA BS mirror and BS chamber on 7, 8th June 2016 by using 3D measurement system. The result are as follows; the mirror was set -1.6mm, -6.2mm, -6.6mm from the planned position inside the vacuum chamber. We also found that the BS chamber was located about +10mm different place in y direction from the planned position if we rely on the position of the floor reference points.
