An analysis of plasma emission by correlation radiometry

Correlation radiometry is proposed as a method of distinguishing between collective and individual particle processes in plasma radiation. Several schemes of correlation radiometry are investigated and the appropriate one is selected to examine correlation between radiation emitted at axially separated points in a beam-plasma discharge column at the harmonics of the electron cyclotron frequency. The correlation measurements establish the usefulness of correlation radiometry and add to the understanding of the collective nature of the cyclotron harmonic emission process.
