Abstract
The laser driven plasma wakefield accelerator is a very compact source of high energy electrons.
When the quasi-monoenergetic beam from these accelerators passes through dense material, high
energy bremsstrahlung photons are emitted in a collimated beam with high flux. We show how a
source based on this emission process can produce more than 109 photons per pulse with a mean
energy of 10 MeV. We present experimental results that show the feasibility of this method of
producing high energy photons and compare the experimental results with GEANT4 Montecarlo
simulations, which also give the scaling required to evaluate its suitability as method to produce
radioisotopes via photo-nuclear reactions or for imaging applications.
