title = "Progress on muon parametric-resonance ionization cooling channel development",
abstract = "Parametric-resonance Ionization Cooling (PIC) is intended as the final 6D coolingstage of a highluminosity muon collider. To implement PIC, a continuous-field twin-helixmagnetic channel with a correlated behavior of the horizontal and vertical betatron motionsand dispersion was developed. A 6D cooling with stochastic effects off is demonstrated in aGEANT4/G4beamline model of a system where wedgeshaped Be absorbers are placed at theappropriate dispersion points in the twin-helix channel and are followed by short rfcavities. To proceed to cooling simulations with stochastics on, compensation of the beam aberrations from one absorber to another is required. Initial results on aberrationcompensation using a set of various-order continuous multipole fields are presented. Asanother avenue to mitigate the aberration effect, we optimize the cooling channel's periodlength. We observe a parasitic parametric resonance naturally occurring in the channel'shorizontal plane due to the periodic beam energy modulation caused by the absorbers and rf.We discuss options for compensating this resonance and/or properly combining it with theinduced half-integer parametric resonance needed for PIC.",
