Plasma accelerators provide unique opportunities for the generation of high quality, short-pulse electrons beams which are an ideal basis for high quality radiation generation. This provides an exciting way forward to the generation of very high brightness X-ray betatron radiation from an ultra-bright, plasma-injected beam in a plasma. In this contribution, we present initial results from studies into the generation of betatron radiation in the keV to MeV range.
The state-of-the-art PIC simulation codes EPOCH and QuickPIC were used to simulate single/double bunch beam dynamics in a plasma channel with different plasma and beam parameters. The results were then analyzed in terms of the number of photons generated and variations in the betatron radiation spectrum in a narrow and wide plasma channel. An optimization of the drive and trailing bunch under matched and mismatched oscillations in a plasma channel was then done to deduce the beam parameters and phase space properties. Finally, the results obtained in both codes are compared against each other for benchmarking purposes.
