Synchrotron Radiation from Runaway Electrons in Plasmas

Highly relativistic runaway electrons are of great concern in the area of fusion energy research, since their presence in tokamak plasmas have the potential to hinder the successful and stable operation of the device, and potentially cause severe structural damage. In this thesis, runaway electron generation dynamics is investigated using the newly developed efficient computational tool CODE. A...

Synchrotron radiation from quasi-monoenergetic electrons

We investigate the spectrum of a quasi-monoenergetic ensemble of relativistic electrons, especially for the mildly relativistic case, and discuss the effect of inclination of the magnetic field on the emissivity. We apply the exact theoretical description to the spectrum of the radio source Sgr A* which is located at or very close to the dynamical center of our Galaxy. We find that the radio-MI...

Ion-Acoustic Wave Radiation from a Point Source in a Streaming Magnetoplasma

We report theoretical and experimental results on the radiation pattern of the ion acoustic waves below the ion cyclotron frequency from a small probe in a streaming magnetoplasma. In the fluid approximation with cold ions the ion acoustic resonance cones are found to be drastically changed. Experimental ray velocities and constant phase surfaces are in good agreement with the theoretical results.

Broadband Radiation from Primary Electrons in Very Energetic Supernovae

A class of very energetic supernovae (hypernovae) is associated with long gamma-ray bursts, in particular with a less energetic but more frequent population of gamma-ray bursts. Hypernovae also appear to be associated with mildly relativistic jets or outflows, even in the absence of gamma-ray bursts. Here we consider radiation from charged particles accelerated in such mildly relativistic outfl...
