Laser-plasma electron accelerators

Recent experimental results with short laser pulses have demonstrated the generation of monoenergetic electron bunches (energy spread < 10%) in the 100s of MeV to GeV energy range. These results have been obtained with laser pulses with intensities close to 1019 Wcm-2, and pulse durations ranging from 80 fs to 30 fs. With longer pulses and higher energies per pulse HiPER provides the opportunity to achieve multi-GeV electron beams for a wide array of applications. The availability within HiPER of different options in terms of pulse length/energy will provide a unique opportunity to explore this field over a wide parameter space, with a view to creating stable mono-energetic relativistic electron beams.
