Evidence of Anomalous Losses of Fusion Products on JET
Fast ion losses in tokamak plasmas are considered to be neo-classical in many applications. Recent fast ion loss measurements of the fusion products on JET have provided information on the loss mechanism of the fusion products. A simulation of the JET fast-ion loss detector data demonstrates that fast fusion tritons and protons may experience superbanana diffusion significantly exceeding the neoclassical level.
