Measurement of Ion Transverse Energy and the Electric Field in the Acceleration Gap of a Magnetically Insulated Diode

Abstract

The electric field and the ion transverse velocities in the gap of a Magnetically Insulated Diode were measured for the first time using visible emission spectroscopy. The technique used utilizes line emission from Ba+ ions accelerated in the gap. The observed Doppler line broadening and the Stark shift yielded the distribution of the ion velocities parallel to the electrodes and the electric field magnitude, respectively. Transverse ion energy of a few hundred electron volts and an electric field about 1.6 times larger than the vacuum field were measured. The inconsistency of the results with a one-dimensional equilibrium is discussed.
