概要
- 論文の詳細を見る
Electron acceleration in magnetic reconnection event has been experimentally investigated using the plasma merging technique in the University of Tokyo Spherical Tokamak (UTST) device. Intense emission of He II line (468.58nm) was observed only in the vicinity of the X-point by using a multi-channel spectroscopic measurement system. This localized emission indicates the generation of energetic electrons inside the current sheet region, possibly due to the electron acceleration by the strong toroidal electric field induced by magnetic reconnection in the presence of a guide field.
