Abstract
A robust emittance exchange system is considered where muons are bunched longitudinally into many bunches and transversely cooled first, then separated into individual time-delay lines where the bunches are synchronized. Finally the bunches are merged by stacking in the transverse momentum space. The longitudinal emittance can be reduced by a maximum factor of N and the transverse emittances can be increased by a minimum factor of in each direction. Emittance dilution may increase the transverse emittance by a factor of 2 ~ 3.
