Shallow Angle Inverse Compton Scattering

Accelerator Physics 2025-09-08 v1

Abstract

Inverse Compton Scattering at shallow angles can be used to tune the spectrum and increase the brightness of the emitted radiation. Here, we report on the demonstration of emission of visible light by a 4.7 MeV ee-beam crossing a 780 nm laser at 5.8o^{\rm o} angle. Angular and spectral measurements of the radiation are in agreement with analytical and numerical predictions. We observe a characteristic dependence on the incoming polarization, not present in conventional head-on scattering, with suppression of the emission for pp-polarization at condition equivalent to relativistic Brewster reflection.
