摘要: A collective Thomson scattering (CTS) system based on CO2 laser is being developed in JT-60U to demonstrate the feasibility of ion temperature and alpha particle measurement international thermonuclear experimental reactor (ITER). new effective method measuring spatial profile absolute detection efficiency an infrared heterodyne receiver has been for CTS system. The viewing area divergence field view were first investigated with this method. Consequently, spot size could be narrowed 0.74 mrad by adjusting focal length local oscillator. sample volume determined injection beam waist was also investigated.
