More control over plasma accelerators
30 Nov 2022
Physicists at the Centre for Advanced Laser Applications at LMU Munich have combined two plasma-based methods of particle acceleration for electron beams.
If one particle accelerator alone is not enough to achieve the desired result, why not combine two accelerators? An international team led by physicists at the Centre for Advanced Laser Applications (CALA) at LMU Munich has implemented this idea. It combined two plasma-based acceleration methods for electrons, namely a laser-driven wakefield accelerator (LWFA) with a particle-beam-driven wakefield accelerator (PWFA). With this combination, the physicists achieve better stability and higher particle density for electron beams than with just a single plasma accelerator. The innovative concept therefore opens up new perspectives for plasma-based particle acceleration.
