Investigation of Acceleration and Densification of Electrons Utilizing Travelling Magnetic Waves
Abstract
Experimental investigation of electron beam physics: naturally occurring and externally driven low frequency (6-500 KHz) diocotron oscillations are observed and the m = 1 rotating structure of these oscillations are measured by using electrostatic probes. Systematic analysis of the circuit system for the generation of a fast-rising pinching magnetic field: a circuit consisted of distributed circuit (transmission line) part and lumped circuit parts included a coil are systematically analyzed from the first principles of circuit. Computer code to calculate expediently the temporal profile of the pinching magnetic is developed. Theoretical study of acceleration of high-energy electron beams by a laser-light through net inverse bremsstrahlung in plasma fields: the absorption of the incident laser photons by net inverse bremsstrahlung can give rise to the dc ponderomotive force whose strength is far greater than the amplitude of the Lorentz force of the laser wave. Study of a soft x-ray free electron laser (FEL) scheme using a two-beam elliptical pill-box wake-field cavity: it is found that the scheme provides sufficient gain as a coherent radiation source down to the x-ray regime. Wake field acceleration research: the theoretical result from the modal analysis developed here agrees with the recent experiment in both profile (shape) and magnitude of the wake potential. Development of a laser photocathode for the generation of high-current short-length electron bunch, and Design and construction of a modified betatron: a modified betatron called the UTA Modified Betatron was constructed.
