	The number of applications that could benefit from effective, affordable muon cooling include stopping muon beams for rare decay searches and spin resonance, intermediate energy beams for neutrino factories and cargo scanning, and muon colliders for HIggs factories and the energy frontier. The simple ionization cooling equation implies that if you have a low-Z energy absorber in a strong magnetic field, sufficient RF to contain the beam and replace the lost energy, and some mechanism for emittance exchange, you can achieve low 6-d emittance down to the limit implied by multiple scattering. The first cooling simulations that were based on a ring were exciting and encouraging. Unfortunately, injection difficulties, beam loading of RF cavities and energy absorbers, and the need to modify cooling parameters as the beam cools have led us away from a ring towards a cooling channel. An effective demonstration experiment must show that the final muon beam parameters to achieve the required luminosity can be achieved at an acceptable cost. We discuss the possibility that a demonstration experiment is a section of a practical, high performance cooling channel.

Parametric-resonance Ionization Cooling (PIC) is proposed as the final 6D cooling stage of a high-luminosity muon collider.

One of the PIC challenges is compensation of beam aberrations over a sufficiently wide parameter range while maintaining the dynamical stability with correlated behavior of the horizontal and vertical betatron motion and dispersion.
