Gyro synchrotron radiation from thermal plasmas

Abstract

The gyro-synchrotron radiation from the solar coronal plasma is investigated with special regard to temperature effects.The influence of non-zero temperature is to enhance the radiated synchrotron power from the solar coronal plasma.We also observe that fast test charges radiate more power than slow charges.In developing a theory of synchrotron radiation it was assumed that temperature effects could be neglected [1, 2, 3], However, the solar plasma cannot be considered as cold. Therefore, the general theory of synchrotron radiation has been modified to account for the background magnetoplasma at finite temperature [4]. The intensity of the gyro-synchrotron radiation1 from weakly relativistic electrons was first derived by Zheleznyakov [4], In this case the velocity of the test charge v = (formula presented) is much smaller than the velocity of light c; in particular the following inequalities are satisfied. © 1972, IOP Publishing Ltd.
