An experimental test of quasilinear theory

摘要: We give a brief summary of an experimental test the quasilinear theory bump on tail instability. Recent theoretical work has suggested that description weak warm beam plasma instability is incomplete. It been mediated mode coupling effects neglected in standard play important role, and their average effect zeroth order increase growth rate. have experimentally observed strong when interacts with waves slow wave structure. However, we do not observe predicted This intriguing result suggests action some statistical or dynamical conservation law whose origin yet theoretically identified.
