GRAND DISRUPTION: A POSSIBLE FINAL FOCUSING MECHANISM FOR LINEAR COLLIDERS
P. Chen · CERN Document Server (European Organization for Nuclear Research) · 1987
Large transverse wake fields can be generated via the interaction between a relativistic electron or positron bunch and a plasma, and the bunch will therefore be self-pinched.In this paper we derive a new and general formulation for the plasma wake field in a compact expression.We then suggest that this self-focusing effect can be used as a mechanism to enhance the luminosity for high energy experiments.A plasma lens based on this effect is suggested with a conceptual design and a numerical example.The problem of background noise is discussed at the end.
