Gamma System Department

"Gamma System Department" is dedicated to the development and operation of a high flux, high brilliance, monochromatic, energy tunable gamma-beam production system based on laser inverse Compton scattering off relativistic electron bunches.

The Gamma Beam Source (ELI-GBS) [ Read more ] at ELI-NP defines a new state–of–the–art gamma beam facility. It will provide gamma beams with energy continuously tunable between 1 MeV and 19.5 MeV, relative energy bandwidth better than 0.5% and a spectral density higher than 5 x 103 photons/s/eV.
