The Cadmium Zinc Telluride 0-Neutrino Double-Beta (COBRA) experiment is a large array of cadmium zinc telluride (CdZnTe) semiconductors searching for evidence of neutrinoless double beta decay and to measure its half-life. COBRA is located underground within the Gran Sasso National Laboratory. The experiment was proposed in 2001, and installation of a large prototype began in 2006.
