Abstract
We study the possibility of producing x-gamma rays with orbital angular momentum by means of the inverse Compton backscattering between a high brightness electron beam and a twisted laser pulse. We use the classical electrodynamics retarded fields for evaluating the orbital angular momentum of the radiation and connecting it to that of the primary laser pulse. We then propose the dimensioning of a linearly polarized x-ray source with orbital angular momentum, starting from the parameters of operating Thomson setups.
Highlights
Optical pulses carrying orbital angular momentum are extremely interesting both from the fundamental point of view and for applications

Summary
Optical pulses carrying orbital angular momentum (referred to as OAM beams) are extremely interesting both from the fundamental point of view and for applications. We study the possibility of producing x-gamma rays with orbital angular momentum by means of the inverse Compton backscattering between a high brightness electron beam and a twisted laser pulse.
