One of the main difficulties to attain economically viable magnetically controlled thermonuclear fusion reactors is the confinement of alpha particles. In toroidally shaped fusion devices with a non-uniform magnetic field, alpha particles with small parallel velocity become trapped between areas of the high field, bouncing between reflection points, that might result in non-zero radial average drifts and their losses. This talk aims to highlight the link between the alpha particle transport and the confining magnetic field with an emphasis on the trapped particle characterization.
FusionEPtalks is brought to you by students and researchers involved in the field of nuclear fusion. Our mission is to do student-led webinars, expert talks and panels on the development of nuclear fusion as an energy source that connect scholars, engineers and enthusiasts around the world.
