Abstract : Interest has developed in the use of deuterium as a replacement for hydrogen in thyratrons, clippers, and rectifiers, due to the apparent ability of deuterium to hold off greater voltages than hydrogen under the same conditions. Deuterium also provides a lower arc drop in the gas. At the same time it has the disadvantage of a longer recovery time after a pulse, because of its increased mass. In view of the increasing use of deuterium as a fill gas, a limited experiment to study the transient cleanup phenomena in deuterium was conducted. It was determined that hydrogen and deuterium transient cleanup obey the same fundamental relationship with respect to discharge parameters. In both cases the percentage cleanup under dynamic operating conditions is directly proportional to the square root of the power dissipated in the tube. There were no apparent differences in the solubility factor of the equation. The prime difference in the behavior of both gases was determined to be the difference in diffusion rates. The experimental techniques, the fundamental relationships, the theoretical considerations, the influence of the physical state of the nickel, and the long-term effects are discussed. (Author)
