Plasma-cascade instability

Physical Review Accelerators and Beams, 2021
In this paper we describe a new microbunching instability occurring in charged particle beams propagating along a straight trajectory. The nature of these exponentially growing plasma oscillations gave the reason for its name: plasma-cascade instability.
