摘要: The possibility of producing femtosecond x-rays through Thomson scattering high power laser beams off wakefield generated relativistic electron is discussed. are produced with either a self-modulated accelerator (SM-LWFA) or standard (LWFA) optical injection. For an SM-LWFA beam, broad (narrow) energy distribution assumed, resulting in x-ray spectra that broadband (monochromatic). Designs presented for 3-100 fs pulses and the expected flux brightness these sources compared.
