Autor: Lumpkin, A. H., LaBerge, M., Rule, D. W., Zgadzaj, R., Hannasch, A., Zarini, O., Bowers, B., Irman, A., Couperus-Cabadag, J. P., Debus, A., Köhler, A., Schramm, U., Downer, M. C.
Publikováno v: Phys. Rev. Lett. 125, 014801 (2020)
We report observations of coherent optical transition radiation interferometry (COTRI) patterns generated by microbunched ~200-MeV electrons as they emerge from a laser-plasma accelerator. The divergence of the microbunched portion of electrons, dedu

A hybrid (LPWFA) plasma accelerator combines the two schemes of plasma acceleration, using a laser (LWFA) and an electron beam (PWFA) to drive the plasma wave, with the goal to combine the advantages of both methods. This concept allows studies of PW

High peak current electron beams from laser wakefield accelerators (LWFA) are capable to drive a particle driven wakefield (PWFA) in a subsequent stage. The intrinsic short duration of these driver beams opens the possibility for PWFA studies in a hi

Few-cycle shadowgraphy is a valuable diagnostic for laser-plasma accelerators to obtain insight into the µm- and fs-scale relativistic plasma dynamics. To enhance the understanding of experimental shadowgrams we developed a synthetic shadowgram diag
