Popis: This paper describes physics research on wave‐plasma interactions in the ion cyclotron range of frequencies (ICRF) and the lower hybrid range of frequencies (LHRF) that takes advantage of advances in large scale computation as well as applied mathematics expertise. A combined Fokker‐Planck and full‐wave solver is used to simulate the interaction of ICRF waves with nonthermal ions generated by the wave itself, with fast ions from neutral beam injection (NBI), and with alpha particles from fusion processes. Finite ion drift orbit effects are included in this analysis through the use of a Monte Carlo approach. Models for simulating the linear and nonlinear interaction of an ICRF antenna with the tenuous edge plasma are also described. Finally we describe advances that have been made to perform a combined full‐wave and Fokker Planck analysis of nonthermal electrons during LH current drive.
