Roberts, S J

A procedure for calculating the theoreticai characteristics of the diffusion model of the gas discharge has been applied to several examples of discharges. These models have had uniform axinl electron drift, and ion temperature determined by electron bombardment. lons and electrons reach the walls by ambipolar diffusion through the neutral gas. For a high degree of ionization, some effects due to recombination have been considered. The tabulated results give complete and consistent characteristics for several discharges, some of which are highly constricted and show the formation of a negative center. Most of the calculations made were for a three-cm radius tube, and show very high power loss for high constriction. Some calculations, however, have been carried out for discharge in a much larger tube, for which the self- magnetic effects can be produced at cost of much less power. This suggests that experiments could be carried out more easily in larger apparatus. (auth)
