ケルビンクランプとスペーサの超精密加工による分割型中性子集光ミラーの組立て調整

抄録

This paper proposes an alignment method for assembling a segmented neutron focusing mirror. Each of the segments of the mirror is mounted on a Kelvin clamp, which is a kinematic clamp composed of three constraints: a point, a line, and a plane constraint. Each of these components is jointly fastened with an aluminum spacer. Thicknesses of the spacers are precisely adjusted by diamond turning, to reduce the relative position/angle errors between segments. The paper also includes results of an actual alignment.
