Thomson X-ray source: basic principles and applications
Abstract
Laser-electron X-ray source based on Thomson scattering is a novel type of laboratory high spectral brightness X-ray sources [1]. Recent advances in high power laser system and electron accelerator technologies have enabled a development of these compact facilities that are able to produce a synchrotron-quality X-ray radiation for material and life science studies, cultural heritage related investigations and many other fields [2-4] at a highly specialized local laboratory. Additional opportunities provided are tight laser/X-ray delay control needed for dynamic studies and tunable spectral properties of theX-ray beam. Besides, the Thomson X-ray source is also known to be the only way to produce monochromatic high energy photon beam s (up to 10 MeV) for continuous sp ectral scan s in nuclear photonics exp eriments. This talk presents the main principles, schem es and current directions of the Thomson X-ray source development, with a special attention being paid to the current projects on the subject in the Institute.
