Preliminary Simulations of FLR Effects on RFP Tearing Modes

摘要

Preliminary simulations of finite Larmor radius (FLR) effects on m = 1 tearing instabilities in a reverse field pinch (RFP) plasma are presented. δ f particle-in-cell (PIC) simulations were performed by extending a hybrid drift kinetic-MHD model to include the full Lorentz equations of motion to take into account finite Larmor radius (FLR) effects. The simulations show that for an idealized phase space distribution, sufficiently energetic ions stabilize the tearing mode. These simulations show good agreement with analytic theory and demonstrate the FLR physics capability of the hybrid kinetic-MHD model.
