Quantify energy transfer during wave-particle resonant interactions

2024 Research Campaign, Frontier Science

Purpose of Experiment

The energy transfer between beam ions and a toroidal Alfven eigenmode will be measured in experiment and simulation from the product of the distribution function f and the wave electric field E.

Experimental Approach

In experiment, imaging neutral particle analyzer measurements will supply f and the electric field will be inferred from measured electron temperature fluctuations and field line tracing. In simulation, f and E will be inferred from calculations by MEGA, a code that models the bulk plasma with resistive MHD and the fast ions kinetically.
