h1. Emittance Exchange 

 h2. Abstract 

 bq. The Muon Ionization Cooling Experiment, MICE, has demonstrated transverse emittance reduction through ionization 
 cooling. Transverse ionization cooling can be used either to prepare a beam for acceleration in a neutrino factory or 
 for the initial stages of beam cooling in a muon collider. Later stages of ionization cooling in the muon collider require 
 the longitudinal emittance to be manipulated using emittance exchange and reverse emittance exchange, where 
 emittance is exchanged from and to longitudinal phase space respectively. A wedge absorber within the MICE cooling 
 channel has been used to experimentally study reverse emittance exchange in ionization cooling. Parameters 
 for this test have been explored in simulation and applied to experimental configurations using a wedge absorber 
 when collecting data in the MICE beam.
