Whistler wave destabilization by a runaway electron beam in COMPASS

Popis výsledku v původním jazyce

A strategy to control the energy of the runaway electron (RE) beam was proposed, which relies on the interaction between high energy electrons and whistler waves (Z. Guo et al., Physics of Plasmas 25, 2018). A model for whistler wave destabilization in presence of a RE beam in COMPASS is proposed. The wave propagation is calculated by a ray tracing method, the linear growth rate of the wave is calculated with analytical formulas valid in the considered experimental conditions. Two different situations are considered: the one in which the waves are injected from the outside by an antenna and the one in which the waves are spontaneously generated inside the RE beam. Multiple reflections of the wave inside the plasma are followed and the positions of maximum wave amplification are identified. Considerations on the optimal wave injection strategy are made.
