Description |
The laser-driven inverse-Compton source generates x-rays by the scattering of a high-energy electron beam off a high-intensity laser pulse in a colliding pulse geometry. We have demonstrated that this source can generate collimated, narrow band x-ray beams in the energy range 0.1-15 MeV. It is shown that 106-107 photons are produced per shot with a peak brightness >1019 photons mm-2 mrad-2 s-1, significantly higher than LINAC-driven devices. The unique characteristics of this source make it ideal for radiography of dense shielded structures, elemental detection as well as providing a unique system to study high-brightness laser-driven electron beams. |
