Abstract We describe the design, construction and performance of the PIBETA detector built for the precise measurement of the branching ratio of pion beta decay, π + →π 0 e + ν e , at the Paul Scherrer Institute. The central part of the detector is a 240-module spherical pure CsI calorimeter covering ∼3 π sr solid angle. The calorimeter is supplemented with an active collimator/beam degrader system, an active segmented plastic target, a pair of low-mass cylindrical wire chambers and a 20…
