Extra management over plasma accelerators

If one particle accelerator alone will not be sufficient to attain the specified outcome, why not mix two accelerators? Physicists have now applied this concept. They mixed two plasma-based acceleration strategies for electrons, particularly a laser-driven wakefield accelerator (LWFA) with a particle-beam-driven wakefield accelerator (PWFA). With this mixture, the physicists obtain higher stability and better particle density for electron beams than with only a single plasma accelerator. The modern idea due to this fact opens up new views for plasma-based particle acceleration.
