【 摘 要 】

We discuss the development of a compact X-ray source based on inverse-Compton scattering with a laser-driven electron beam. This source produces a beam of high-energy X-rays in a narrow cone angle (5-10 mrad), at a rate of 10(8) photons-s(-1). Tunable operation of the source over a large energy range, with energy spread of similar to 50%, has also been demonstrated. Photon energies >10 MeV have been obtained. The narrowband nature of the source is advantageous for radiography with low dose, low noise, and minimal shielding. (C) 2015 Elsevier B.V. All rights reserved.
