| Research Abstract |
Doppler shift of Hαspectral lines were measured in the central cathode plasma generated by an Inertial-Electrostatic Confinement discharge in He/H2mixture. Acceleration voltages were estimated from the observed maximum shift of near wings of Hα, and agreed with potential differences between the plasma center and the cathode, estimated from the potential profiles measured by the laser-induced fluorescence method. This suggests that excited H atoms are generated by charge-exchange reactions of H ions accelerated by the potential formed inside the cathode with backgroundH atoms or molecules.
