A high-luminosity Muon Collider requires bunch recombination for optimal luminosity. In this report, we take advantage of the large slip factor in a helical transport channel (HTC) to coalesce bunches of muons into a single one over a shorter distance than can be achieved over a straight channel. To reduce complications associated with matching out of upstream and into downstream subsystems, we designed the bunch coalescing subsystem with a value for the slip factor that is representative of an existing helical cooling channel (HCC) design. Alternate designs have been developed to investigate the tradeoffs between simplifications in reducing the number of RF cavities versus performance. All key components of the bunch coalescing subsystem have been simulated in 3-D.
