Plasma acceleration and new acceleration techniques constitute a research area focused on generating high-gradient particle acceleration using collective electromagnetic fields in plasmas and other nonconventional media, surpassing the gradient limits of radio-frequency cavity accelerators. This includes plasma wakefield acceleration driven by intense laser pulses or charged particle beams, beam-driven and laser-driven dielectric structures, and novel concepts such as structure-based wakefields and micro-accelerators. Research emphasizes understanding nonlinear plasma dynamics, beam loading, stability, staging, and emittance preservation, as well as developing advanced diagnostics and control schemes, with applications in compact high-energy accelerators, ultrafast radiation sources, and future collider concepts.
Laser-plasma accelerators take up less space than conventional facilities, which are sometimes kilometers long. Such compact particle sources can accelerate electron bunches efficiently, enabling X-ray lasers that fit in ...
