: Article: Compact tunable Compton x-ray source from laser-plasma
: accelerator and plasma mirror
: ABSTRACT: We present results of the first tunable Compton back-
: scattering (CBS) x-ray source that is based on the easily
: aligned combination of a laser-plasma accelerator (LPA) and a
: plasma mirror (PM). The LPA is driven in the blowout regime by
: 30 TW, 30 fs laser pulses, and produces high-quality, tunable,
: quasi-monoenergetic electron beams. A thin plastic film near
: the gas jet exit efficiently retro-reflects the LPA driving
: pulse with relativistic intensity into oncoming electrons to
: produce 2×107 CBS x-ray photons per shot with 10-20 mrad
: angular divergence and 50 % (FWHM) energy spread without
: detectable bremsstrahlung background. The x-ray central energy
: is tuned from 75 KeV to 200 KeV by tuning the LPA e-beam central
: energy. Particle-in-cell simulations of the LPA, the drive
: pulse/PM interaction and CBS agree well with measurements.
