High-Power Beam Source and Beam Transmission

This research explores high-power beam sources and their transmission, crucial components for applications involving beamed energy propulsion and power transmission. This paper introduces key aspects of electromagnetism, including the properties of Gaussian beams and the correlation between beam diameter and frequency. Various oscillation sources are discussed, with emphasis on devices like the magnetron, klystron, gyrotron, and free-electron laser. The exploration of high-power beam source technology examines gyrotron tubes, high-voltage power supply, superconducting magnets, matching optical units, and auxiliary systems. The study further looks into transmission technology, reviewing waveguides, miter bends, dummy loads, and power selection and control equipment. An electronic cyclotron heating system for fusion plasma serves as an illustrative example of high-power beam sources.
