A new Detector Design for Electron Spectroscopy in Neutron Beta Decay — •Christoph Roick1, Bastian Märkisch1, Lukas Raffelt2, Heiko Saul1,3, and Ulrich Schmidt2 — 1Physik-Department ENE, TU München — 2Physikalisches Institut, Universität Heidelberg — 3Atominstitut, TU Wien
The upcoming versatile instrument PERC will significantly increase the precision in neutron beta decay studies. This also demands new developments in electron detector design.
In this talk we present a new scintillator based detector setup featuring machine milled light guides, temperature stabilized photomultiplier tubes and a conductive coating. This system can be used for electron spectroscopy or coincident electron-proton-detection. During a recent measurement of the proton asymmetry with Perkeo III, we could prove that a superior performance in light yield at similar spatial homogeniety compared to former detectors with and without coating is achieved.
