Background studies for the ECHo experiment

  • 1. Kepler Center for Astro and Particle Physics, Eberhard-Karls-Universitaet Tuebingen (Germany)

Description

The ECHo experiment is going to measure the the endpoint of the spectrum of the 163Ho electron capture at 2.833 keV, which offers great potential to reach sub-eV sensitivity on the absolute neutrino mass mνe. In order to achieve this sensitivity, the low energy background below 3 keV has to be thoroughly understood and reduced as much as possible. The background spectra of radioactive contaminants 40K, 166mHo and 210Pb in the surrounding structures of the detectors have been investigated via GEANT4 Monte-Carlo simulations. The results of our studies with respect to the tolerable contamination levels and the necessary improvements in the simulation software are presented in this contribution.
