Twisted electrons affect x-ray energy and angular distribution.

Structured x-ray beams can be generated with specific electron states.

Tailor-made x-ray profiles are achievable beyond plane-wave electron limitations.

Abstract

The inverse Compton scattering of laser light on high-energetic twisted electrons is investigated with the aim to construct spatially structured x-ray beams. In particular, we analyze how the properties of the twisted electrons, such as the topological charge and aperture angle of the electron Bessel beam, affects the energy and angular distribution of scattered x-rays. We show that with suitably chosen initial twisted electron states one can synthesize tailor-made x-ray beam profiles with a well-defined spatial structure, in a way not possible with ordinary plane-wave electron beams.
