Mathematical Analysis of Three Free-Electron-Laser Issues

摘要

The central idea underlying this project was that sideband instabilities could becontrolled by optical guiding effects through the radiation of slippage between electron bunches and the radiation field. However, none of the related six research objectives in the original proposal to AFOSR has been truly complete. The principal advances made during the period of AFOSR support include: the recognition that enhanced radiation pressure can produce disruptive velocity changes in the presence of slippage (ITR1), the viability of an electron macroparticle model of sideband instabilities (ITR2), and an analysis (including radiative reaction) of the analogous problem of resonance scattering (ITR2). The recognition that electrostatic waves could correlate repelling particles on a length scale much shorter than a wavelength (ITR2) led the PI to an important application to anomalous transport in turbulent plasma.
