  Emittance exchange mediated by wedge absorbers can be used for longitudinal
ionization cooling and for final transverse emittance minimization for a muon
collider. A wedge absorber within the Muon Ionization Cooling Experiment (MICE)
could serve as a demonstration of the type of emittance exchange needed for
six-dimensional (6D) cooling, including the configurations needed for muon
colliders. Parameters for this test have been explored in simulation and
applied to experimental configurations using a wedge-shaped absorber. A
polyethylene wedge absorber has been fabricated and placed in MICE and data has
been collected for both direct emittance exchange, where the longitudinal
emittance decreases, and reverse emittance exchange, where the transverse
emittance decreases. The simulation studies that led to the magnet and beam
configurations are presented.
