  • Fast Alpha Particle Distribution in the Presence of Anomalous Spatial Particle Diffusion 

    García Carrasco, Álvaro (Universitat Politècnica de Catalunya / Chalmers Tekniska Högskola, 2011)
    Master thesis (pre-Bologna period)
    Open Access
    The high-energy alpha particle population in an ignited D-T fusion plasma may cause thermonuclear wave instabilities, which could lead to anomalous losses of plasma energy and of energetic alpha particles. On the other ...
