Abstract

The detector built at KEK to search for T-violating transverse muon polarization in K⁺→π⁰μ⁺ν_μ(K_μ3) decay of stopped kaons is described. Sensitivity to the transverse polarization component is obtained from reconstruction of the decay plane by tracking the μ⁺ through a toroidal spectrometer and detecting the π⁰ in a segmented CsI(Tl) photon calorimeter. The muon polarization was obtained from the decay positron asymmetry of muons stopped in a polarimeter. The detector included features which minimized systematic errors while maintaining high acceptance.
