Hollow Cathodes 315 produce sufficient plasma density to carry the discharge current, and the lower electron temperatures and collisional effects in the cathode plume plasma tend to damp or extinguish the oscillations. This oscillatory and damping behavior is suggested by the cathode plume models [39,41,72,73] in the literature and discussed above. References [1] D. M. Goebel, K. Jameson, I. Katz, and I.
