Emittance and Phase Space Exchange

Alternative chicane-type beam lines are proposed for exact emittance exchange between horizontal phase space (x; x(prime)) and longitudinal phase space (z; (delta)). Methods to achieve exact phase space exchanges, i.e. mapping x to z, x(prime) to (delta), z to x and (delta) to x(prime) are suggested. Methods to mitigate the thick-lens effect of the transverse cavity on emittance exchange are discussed. Some applications of the phase space exchanger and the feasibility of an emittance exchange experiment with the proposed chicane-type beam line at SLAC are discussed.
