“…Electrons from a conventional accelerator can be injected into the wakefield, but matching the beam properties to the wakefield size is difficult leading to low efficiency of particle trapping [32]. A number of advanced techniques have been proposed and demonstrated that use density modification [33][34][35], secondary laser beams [36][37][38] or ionization [39][40][41] to greatly simplify injection into the wakefield.…”

Advances in X-ray imaging techniques have been driven by advances in novel X-ray sources. The latest fourth-generation X-ray sources can boast large photon fluxes at unprecedented brightness. However, the large size of these facilities means that these sources are not available for everyday applications. With advances in laser plasma acceleration, electron beams can now be generated at energies comparable to those used in light sources, but in university-sized laboratories. By making use of the strong transverse focusing of plasma accelerators, bright sources of betatron radiation have been produced. Here, we demonstrate phase-contrast imaging of a biological sample for the first time by radiation generated by GeV electron beams produced by a laser accelerator. The work was performed using a greater than 300 TW laser, which allowed the energy of the synchrotron source to be extended to the 10–100 keV range.

“…To achieve these values, an XFEL laser beam ofhω = 100 eV, can be used to produce and accelerate an electron beam (as is described in Refs. [47][48][49][50]) which collides head on with the same focused XFEL laser beam. Again in the electron's frame of reference, photon energy will transform tohω * = γ Lh ω where the Lorentz factor is γ L = E e-beam /mc 2 .…”

Numerical estimates for electrons and mesons particle-antiparticle creation from vacuum in the presence of strong electromagnetic fields are derived, using the complete probability density relation of Popov's imaginary time method (Popov, JETP Lett. 13, 185 (1971) (2002)), and within the framework of an experimental setup like the E144 (Burke et al., Phys. Rev. Lett. 79, 1626Lett. 79, (1997). The existence of crossing point among pair creation efficiency curves of different photon energies and the role of odd/even multiphoton orders in the production rates are discussed. Finally a kind of tunability process between the two creation processes is discussed.
