Abstract

A number of experiments are underway to search for a rare form of radioactivity, neutrinoless double beta decay, as a measurement of the half-life would enable the neutrino mass to be determined. The COBRA collaboration [1,2] (Zuber, 2001: Dawson, 2009) employs CdZnTe detectors in such a search. This paper describes techniques using pulse shape analysis for identifying two-centre events in a coplanar grid CdZnTe detector. This enables Compton scatter events to be identified and so suppressing the background present within the COBRA detectors. (C) 2010 Elsevier B.V. All rights reserved.
