High precision experiments in neutron beta decay can solve open questions in particle physics and cosmology [1, 2]. Main emphasis lies on the search for evidence of possible extensions of the Standard Model (e.g., SUSY, right handed currents, etc.). The new user facility 'Proton and Electron Radiation Channel' (PERC) is designed to provide a high intensity beam of charged neutron decay products. The phase space of the particle beams can be precisely selected by the adjustable instrument setup. That way, we can measure energy spectra and angular correlation coefficients of the decay products with unprecedented precision [3] and determine unmeasured parameters, e.g., the Fierz interference term.
PERC is under development by an international collaboration and will be installed at the FRM II in Munich, Germany. The Vienna group focuses on the PERC instrument design as well as energy and momentum spectroscopy of the decay products in the analyzing area. The completed magnetic field design and design proposals for post-spectrometers will be presented on this poster.
