Abstract
Compton scattering of a laser beam with a relativistic electron beam has been used to generate intense, highly polarized and nearly monoenergetic x-ray or gamma-ray beams at many facilities. The ability to predict the spatial, spectral and temporal characteristics of a Compton gamma-ray beam is crucial for the optimization of the operation of a Compton light source as well as for the applications utilizing the Compton beam. In this paper, we present two approaches, one based upon analytical calculations and the other based upon Monte Carlo simulations, to study the Compton scattering process for various electron and laser beam parameters as well as different gamma-beam collimation conditions. These approaches have been successfully applied to characterize Compton gamma-ray beams, after being benchmarked against experimental results at the High Intensity Gamma-ray Source (HIGS) facility at Duke University.
Highlights
Compton scattering of a laser beam with a relativistic electron beam has been successfully used to generate intense, highly polarized, and nearly monoenergetic x-ray or gamma-ray beams with a tunable energy at many facilities [1,2,3]
These unique Compton photon beams have been used in a wide range of basic and application research fields from nuclear physics to astrophysics, from medical research to homeland security and industrial applications [1]
We present two different methods, a semianalytical calculation and a Monte Carlo simulation, to study the Compton scattering process of a polarized laser beam with an unpolarized electron beam in the linear Compton scattering regime
Summary
Compton scattering of a laser beam with a relativistic electron beam has been successfully used to generate intense, highly polarized, and nearly monoenergetic x-ray or gamma-ray beams with a tunable energy at many facilities [1,2,3]. We present two different methods, a semianalytical calculation and a Monte Carlo simulation, to study the Compton scattering process of a polarized (or unpolarized) laser beam with an unpolarized electron beam in the linear Compton scattering regime. Using these two methods, we are able to characterize a Compton gammaray beam with various laser and electron-beam parameters, arbitrary collision angles, and different gamma-beam collimation conditions.
