Kim Chong-kyun received the 38th Annual Meeting of the Young Society of Young Scientists (Student Member Category) at the Annual Meeting of the Japan Society of Plasma Science and Technology. The title is “Development of a spectroscope for tunable Thomson scattering measurement using two interference filters”. In the past, it was necessary to use a large number of expensive interference filters for the Thomson scattering filter spectroscope, but focusing on the difference in the selected wavelength depending on the angle of incidence on the interference filter, Thomson scattering is practical with only two interferometers. Succeeded in constructing a filter spectroscope for. This success has made it possible to significantly reduce the cost of the filter spectroscope, and it is expected that the two-dimensional Thomson scattering, which was successfully developed in our laboratory, will be able to achieve high resolution at low cost.
