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

Rising interest in inverse Compton sources has increased the need for efficient models that properly quantify behavior of scattered radiation given a set interaction parameters. The current state-of-the-art simulations rely on Monte Carlo--based methods, which, while expressing scattering high-probability regions produced spectra, may not correctly simulate such low-probability (e.g. tails spectra). Moreover, sampling take an inordinate amount time desired accuracy to be achieved. In this...

Wakefield wavelengths associated with solid-state plasmas greatly limit the accelerating length. An alternative approach employs 2D carbon-based nanomaterials, like graphene or carbon nanotubes (CNTs), configured into structured targets. These nanostructures are designed voids low-density regions to effectively reduce overall plasma density. This reduction enables use of longer-wavelength lasers and also extends wavelength acceleration In this study, we present, our knowledge, first...

We present a new paradigm for computation of radiation spectra in the non-linear regime operation inverse Compton sources characterized by high laser intensities. The resulting simulations show an unprecedented level agreement with experiments. Increasing intensity changes longitudinal velocity electrons during their collision, leading to considerable broadening scattered spectra. effects such ponderomotive are so deleterious that most either remain at low intensities or pay steep price...
