Description

Reaching $10^{34}$ $\rm{cm}^{-2}s^{-1}$ luminosity range in a $10$ TeV Muon Collider within the short lifetime of the muon requires the reduction of the 6D emittance of the muon beam in a process described as muon ionization cooling. In the final cooling stage, the transverse emittance must be reduced to $22 \mu$m, typically by allowing longitudinal emittance growth up to downstream acceptance limits. While the current International Muon Collider Collaboration designs additionally involve $40$ T solenoids to reach the transverse emittance target, such high-field solenoids come with a number of disadvantages, including mechanical stress management, quench protection, and potential limitations in relying on High Temperature Superconductor technology. Designed as an alternative to using such solenoids while simultaneously reaching target transverse emittance, the previously proposed wedge-based, reverse emittance-exchange cooling scheme requires excellent dispersion suppression. In this study, we design and simulate a dispersion suppressor channel for the wedge-based final cooling design that reduces dispersion in the target direction to a target value of $D_x = 0.0036$ m.
