Abstract

In the hot ion mode of the tandem mirror GAMMA 10/PDX experiments, increases in the flux and temperature of end-loss electrons were observed after the excitation of Alfvén ion cyclotron (AIC) modes. The increase of the electron temperature in the central cell is directly observed using a Thomson scattering system, confirming electron heating due to the electron Landau damping of AIC modes.
