Electron Spectroscopy with PERC — •Karina Bernert1, Jens Klenke2, Max Lamparth1, Manuel Lebert2, Kathrin Lehmann2, and Bastian Märkisch11Technische Universität München, Garching, Germany — 2Forschungsreaktor München, Garching, Germany

The PERC (Proton Electron Radiation Channel) instrument is a neutron decay facility currently being set up at the research reactor FRM II of the Heinz Maier-Leibnitz Zentrum in Garching. Its main component is a 12-meter long superconducting magnet system, which was recently delivered to the FRM II. We aim to measure several correlation coefficients in neutron beta decay one order of magnitude more precisely than currently possible. From the results, we will derive the nucleon axial coupling and the CKM matrix element Vud and search for scalar and tensor couplings.
The spectrum of electrons from neutron decay will be obtained using two detector systems: the primary detector downstream will be a scintillation or silicon detector. The secondary detector system, used to identify backscattering events, consists of two pixelated scintillation detectors read out by silicon photomultipliers. In this talk, we present the status of the experiment and its main components with a focus on the backscatter detector.
PERC is developed in cooperation with scientists from TU Vienna, Universität Heidelberg, Johannes Gutenberg-Universität Mainz and the ILL.
