Electron Temperature Measurement by Electron Cyclotron Emission from Tandem Mirror GAMMA 10

Abstract
Measurements of electron cyclotron emission were carried out in order to estimate the electron temperature in the central and plug cells of a tandem mirror, GAMMA 10. The emission from hot electrons is substracted by considering a relativistic shift of resonance layers. The plug electron temperature is much larger than the central one, which represents a reduction of thermal conduction across the thermal barriers.
