Study of Ionization Cooling with the MICE Experiment¶
- Study of Ionization Cooling with the MICE Experiment
The international Muon Ionization Cooling Experiment (MICE) will demonstrate the ionization cooling of muons; the only known
technique that can provide high brightness muon beams suitable for applications such as a Neutrino Factory or Muon Collider.
MICE is underway at the Rutherford Appleton Laboratory and has recently taken the data necessary to characterise the physical
processes that underlie the ionization-cooling effect. Measurements of the change in normalised transverse amplitude are
presented in two configurations. The measurements of the ionization-cooling effect are discussed.

Modelled magnetic field for the configuration on the axis and with 160 mm horizontal displacement from the axis. Hall probes, situated 160 mm from the beam axis, show a 2 $\%$ discrepancy with the model. Dashed lines show position of the tracker stations and absorber.
Design optics for the configuration. Dashed lines show position of the tracker stations and absorber.
Change in amplitude distribution for the `3-140' configuration (top) and for the `6-140' configuration (bottom). The transmission is around 90 $\%$ and 80 $\%$ respectively. (Blue circles) amplitude of all upstream events; (red triangles) amplitude of all downstream events; (magenta squares) amplitude of upstream events that are not observed downstream.
