Fig. 1: Schematic layout of the MICE experimental setup and the modelled magnetic field.
From: Transverse emittance reduction in muon beams by ionization cooling

a, Powered magnet coils are shown in red, absorber in green and detectors are individually labelled (see the main text for descriptions). TOF0, TOF1 and TOF2 are TOF hodoscopes; KL is a lead–scintillator pre-shower calorimeter; EMR is the electron–muon ranger. b, Modelled longitudinal magnetic field Bz is shown along the length of the MICE channel on axis (black line) and at 160 mm from the beam axis (green line) in the horizontal plane. The measurements of Hall probes situated at 160 mm from the axis are also shown (green circles). The vertical dashed lines indicate the positions of the tracker stations and the absorber.
