For ITER-class long-pulse beam acceleration for 3600s, diagnostic tools are newly developed to withstand the harsh thermal heat flux of 200MW/m^2 beam power density. One of methods is the beam emittance diagnostics system through thermal imaging of the multiple beamlets using a one-dimensional carbon-fiber composite target. This thermal measurement method is being examined for realistic implementation to beam monitoring and the operational schemes and specifications will be discussed., 負イオン研究会2018}, title = {2D Beam Diagnostics Technique using Thermal Imaging for ITER-class High Power Negative Ion Beams}, year = {2018} }
