WebFlute instability was observed at the plasma-field interface, which presents a salient kinetic feature rather than classical fluid instability. In the initial linear phase, the growth rate of the perturbation has good agreement with Large Larmor radius instability, which is larger than ion gyrofrequency. WebThe increase in fluctuations for the half-magnetic field experiments is expected due to the high frequency fields increasing the plasma temperature which increases the instability growth rate. The decrease in fluctuations for the nominal magnetic field experiments must be explained by a stabilizing mechanism.
