Fig. 2: Simulated MICE muon beam betatron function.
From: Transverse emittance reduction in muon beams by ionization cooling
Evolution of the simulated transverse betatron function β⊥ through the cooling channel containing the full LH2 vessel for the parent beam (black) and matched subsample (dark cyan). The corresponding lines represent the simulation truth, whereas the circles and squares at the tracker stations (vertical blue lines) represent the reconstructed simulation. The thick vertical blue line marks the central position of the absorber. The error bars show the statistical standard error and are smaller than the markers for all the points.
