Title: Design of collection optics and polychromators for a JT-60SA Thomson scattering system

Abstract

This paper presents designs of collection optics for a JT-60SA Thomson scattering system. By using tangential (to the toroidal direction) YAG laser injection, three collection optics without strong chromatic aberration generated by the wide viewing angle and small design volume were found to measure almost all the radial space. For edge plasma measurements, the authors optimized the channel number and wavelength ranges of band-pass filters in a polychromator to reduce the relative error in T{sub e} by considering all spatial channels and a double-pass laser system with different geometric parameters.
