Microwave emissions from turbulent plasmas generated in a fast, high voltage theta pinch

Abstract

Intense, and evidently nonthermal, bremsstrahlung has been observed from turbulent helium plasmas that were generated in a large, high voltage theta pinch operated in two different experimental configurations. The emissions were in the wavelength range 1 mm ≲ λ ≲ 16 mm, and are identified as collective bremsstrahlung, originating from the interaction of longitudinal modes of the turbulent plasmas by wave-wave scattering.
