| Research Abstract |
Thomson scattering diagnostics provide electron temperature and density in the plasma. It is found that electron temperature can be measured even if changes in transmissivities (efficiencies) of the optical components are unknown. The relative transmissivities are also obtained using the electron temperature without any direct calibrations. In addition to the initial aims of this study, simulations of the measurement accuracy clarify that this method is effective even in severe radiation circumstances generated by burning plasma experiments.
