Low background signal readout electronics for the MAJORANA DEMONSTRATOR
I Guinn, N Abgrall, IJ Arnquist, FT Avignone… - AIP Conference …, 2015 - pubs.aip.org
The MAJORANA Collaboration will seek neutrinoless double beta decay (0ν β β ) in 76Ge
using isotopically enriched p-type point contact (PPC) high purity Germanium (HPGe)
detectors. A tonne-scale array of HPGe detectors would require background levels below 1
count/ROI-tonne-year in the 4 keV region of interest (ROI) around the 2039 keV Q-value of
the decay. In order to demonstrate the feasibility of such an experiment, the MAJORANA
