Neutron beams represent well-established systems for a large variety of fundamental physics research. In particular, neutron beta decay opens up a series of possibilities for a detailed study of the weak interaction within the standard model of particle physics and possible extensions beyond it. Among other observables, a large number of correlation coefficients in neutron beta decay may be determined by high-precison experiments, providing a complementary way to high-energy accelerator experiments of gaining related knowledge.

PERC, a new facility for the high-precison experimental study of neutron beta decay is currently under construction. It consists of a specifically tailored superconducting magnet system to guide the charged neutron decay products and a special neutron guide arrangement to conserve the initial neutron phase space density. In this presentation, the concept and design of the facility will be discussed, various components will be presented and information of the current status will be given.
