説明

A new relativistic guiding center orbit code (RGCO) has been developed and used to investigate the confinement mechanism of energetic electrons in QUEST tokamak. Benefiting from the orbit simulation in cylindrical coordinates, the particle tracking can be performed within the entire first wall, including the main plasma and the scrapeoff layer (SOL), so it can provide a more realistic evaluation of the confinement and loss of the particle than previous results. Detailed analyses reveal that energetic electrons can be confined both inside and outside the last closed flux surface (LCFS) inside the first wall of QUEST tokamak, thus contributing to the non-inductive current driving. In future work, the confinement and loss mechanism of alpha particle will be researched through energetic electron in QUEST by physics experiment combined with the RGCO code simulation.
