Increases in the flux and temperature of end-loss electrons are observed following excitation of an Alfvén ion cyclotron (AIC) mode in the GAMMA 10 tandem mirror. Electron loss power carried to an end wall becomes more than twice as large as that without the AIC mode. The increases in the electron flux and temperature are observed only when the parallel phase velocity of the AIC mode matches with the electron thermal velocity, strongly suggesting that the parallel electron acceleration is due to electron Landau damping of the AIC mode.
