Abstract

In UTST device, magnetic reconnection with strong guide-field (strong guide-field reconnection) takes place during the ST merging period. To evaluate the energy conversion by magnetic reconnection quantitatively, the measurement of the electron temperature and density with a high confidence and accuracy is required. We developed a novel slide-type two-dimensional Thomson scattering measurement system to evaluate electron heating during strong guide-field magnetic reconnection in the UTST device.
