The PERC facility at the MEPHISTO beam line at the FRM II research reactor of the Maier-Leibnitz Zentrum (MLZ) aims to measure several observables in neutron decay with an order of magnitude improvement in precision in order to determine constants within the Standard Model of particle physics precisely and to search with improved sensitivity for new physics beyond it.
Its main component is a ~12m long superconducting magnet system which produces a magetic field between 1 to 6T within a 30-35cm bore mostly in direction along its length. This field is used to guide charged particles to detector systems, separating them from the cold neutron beam.
