abstract:	Several promising schemes for high-gradient acceleration of charged particles in planar electromagnetic structures have been recently proposed. In this paper we investigate, by both computer simulation and theoretical analysis, the longitudinal and transverse wake-fields experienced a relativistic charged particle in a planar structure. We show that, in the limit of a large aspect ratio beam, the net deflecting wake-fields vanishes. Practical implications of this result for short wavelength advanced accelerators are discussed.

title:	A Linear Collider Based on Nonlinear Plasma Wake-field Acceleration
format:	conference procceeding
conference:	Summer Study on New Directions for High Energy Physics
year:	1997

abstract:	A proposal for a linear collider based on an advanced accelerator scheme, plasma wake-field acceleration in the extremely nonlinear regime is discussed. In this regime, many of the drawbacks associated with preservation of beam quality during acceleration in plasma are mitigated. Experimental progress towards high-gradient acceleration in this scheme is reviewed. We then examine a linear collider based on staging of many modules of plasma wake-field accelerator, all driven by a high average current, pulse compressed, rf photoinjector-fed linac. Issues of beam loading, efficiency, optimized stage length, and power efficiency are discussed. A proof-of-principle experimental test of the staging concept and the Fermilab Test Facility is discussed.
