Betatron radiation as bright hard X-ray source and effective diagnostic for laser-plasma acceleration experiments.
Curcio A., Giulietti D.
The betatron radiation from laser-plasma accelerated electrons typically extends in the X-ray region, with a broad synchrotron-like incoherent spectrum. Nevertheless the radiation spectrum and the degree of coherence of the betatron radiation can be efficiently modified according to different laser-plasma interaction schemes. The idea of a plasma undulator is so far unrealizable, but a deep study of the betatron radiation mechanism is necessary towards this aim.
