k₁₂, East Hall, Experiment S93: Λ p total cross-section measurement

A view of the apparatus used for the Λp total cross-section measurement at the time of its installation. The hyperons decaying into a proton and a pion in the conical tank in front were detected in the magnet spectrometer in the upper half of the picture. A novel detection technique using exclusively multiwire proportional chambers was employed.
