| Publication Abstract: | Transverse-longitudinal emittance exchanges using deflecting cavities have been under study and in operation for some time [1, 2]. Such exchanges can also be performed using a pair of cavities operated in bunching (or debunching) mode embedded in a sequence of bending beamlines. Exchanges of this type can be characterized using either an integral solution for the equations of motion in such a system, or a transfer matrix parameterization. We summarize both approaches, derive beamline requirements for the linear optics of a system of this type using a matrix representation, and present a design concept and example design.
