Thermal energy balance in a low-pressure microwave surfatron
Abstract
The radial heat flow along the plasma column in Xe in a microwave surfatron was investigated experimentally at pressures of 0.5-1.2 tor. The results demonstrate the important role of losses associated with energy transfer to the walls by positive ions accelerated by the ambipolar diffusion field and by the potential gradient near the wall of the discharge tube. This loss channel is particularly efficient in heavy gases. Under the experimental conditions, the properties of the discharge along its entire length can be described by a single kinetic plasma model.
