Abstract
We examined the anode plasmas of pulsed ion diode spectroscopically. A cryogenic diode was used. At first, we investigated the surface flashover process of low temperature materials. We found that there existed a large amount of neutral gas emission during the surface flashover and the temperature dependence of the surface breakdown voltage. Next, we chose H20 and D20 ices as the ion sources, and produced ion beams with the cryogenic anode cooled down to 77K. The electron number density and the temperature of the anode plasma were estimated spectroscopically. Our results showed that the neutral gas emission strongly affected the anode plasma initiation, the anode plasma density, and the temperature. It was also confirmed that the degree of ionization had some profiles in the anode plasma and the expansion velosity of the anode plasma did'nt change with the atomic mass.
