Emittance and phase space exchange for advanced beam manipulation and diagnostics

Abstract

Alternative chicane-type beam lines are proposed for exact emittance exchange between transverse phase space (x,x′) and longitudinal phase space (z,δ), where x is the transverse position, x ′ is the transverse divergence, and z and δ are relative longitudinal position and energy deviation with respect to the reference particle. Methods to achieve exact phase space exchanges, i.e., mapping x to z, x′ to δ, z to x, and δ to x′, are suggested. Schemes to mitigate and completely compensate for the thick-lens effect of the transverse cavity on emittance exchange are studied. Some applications of the phase space exchange for advanced beam manipulation and diagnostics are discussed.
