Whistler-Mode Electron Cyclotron Emission in a Mirror Plasma

Abstract
Measurements of electron cyclotron emission in the whistler mode have been made on the Maryland mirror machine and the results are compared with hot-plasma theory. Good agreement is obtained, demonstrating, in particular, that the emission attains black-body levels for a wide range of conditions. It is concluded that this emission is a promising candidate to measure axial variations of the electron temperature in tandem mirror devices.
