Neutron Beta Decay with PERC

The PERC collaboration will perform high-precision measurements of angular correlations in neutron beta decay. The new beam station PERC, a clean, bright, and versatile source of neutron decay products, is designed to improve the sensitivity of neutron decay studies by one order of magnitude. The charged decay products are collected by a strong longitudinal magnetic field directly from inside a neutron guide. This combination provides the highest phase space density of decay products. A magnetic mirror serves to limit the phase space precisely, reducing related systematic errors.
The PERC instrument is funded within the Priority Programme SPP 1491 "Precision experiments in particle- and astrophysics with cold and ultracold neutrons" of the German Research Foundation. PERC is under development by an international collaboration. The instrument will be set up at the beam facility MEPHISTO of the Forschungs-Neutronenquelle Heinz Maier-Leibnitz in Munich, Germany.
