Characterisation of monoenergetic electron beams produced at the Lund Laser Centre

In English Experiments performed with the high contrast 0.7 J, 35 fs Ti:Sapphire laser at the Lund Laser Centre focused into a supersonic helium gas jet have demonstrated the production of quasi-monoenergetic electron beams with energies up to 150 MeV. The beam is a result of controlled wavebreaking of a wakefield generated by the relativistically channeled laser beam. Under the best conditions of laser energy and plasma density, a monoenergetic beam was produced on every shot with energy stability ~10% and a pointing stability of ~6 mrad. This marks a significant improvement in the repeatability of laserplasma generated electron beams.
