Abstract

In the particle acceleration by stimulated emission of radiation (PASER), the efficient interaction occurs when a train of micro-bunches whose periodicity being identical to the resonance frequency of the medium. The previous theoretical calculations based on the simplified model consider only the energy exchange in the boundless condition, under the experimental condition, however, the gas active medium must be guided by the metal waveguide. In this paper, we have developed the model of energy exchange between a train of micro-bunches and gas mixture active medium in waveguide boundary for the first time based on the Theory of Electromagnetic Fields, and made detailed analysis and calculations with MathCAD. The results show that the energy density could be optimized to a certain value to get the maximum energy exchange.
