It is located within the Gran Sasso National Laboratory (LNGS). Papers on this method have been published since 2001 and installation of a large prototype began in 2006.〔(), (2, The Cobra Experiment, J.R. Wilson, University of Sussex, 2008 )〕 == Set up == The COBRA experiment is currently in the research & development stages, in order to prove the validity of the proposed techniques.〔()(Sasso COBRA section )〕 The initial set up of the experiment was an array of four 1-cm^3 CZT semiconductors in 2007.〔()(results on double β-decay modes of Cd, Te, and Zn Isotopes, T.Bloxham et al. , Phys. Rev. C 76, 025501, 2007 )〕 Currently, the experiment is composed of 64 1-cm^3 detectors in a 4x4x4 array, 32 of which are currently active.〔()(Sasso Website )〕 The CdZnTe crystals act as both detector and source material, as nine of the isotopes in this material are possible double beta decay candidates.〔()(1, Current Status and Future Perspectives of the COBRA Experiment, J. Ebert et. al, 2013 )〕 The location of the experiment allows for shielding from external gamma rays, to this end, the detectors are also shielded by 5 cm of radiopure electrolytic copper and 20 cm low-radioactivity lead. 7 cm of boron-loaded polyethylene shields the experiment against neturons, and the experiment is constantly flushed with nitrogen gas to prevent contamination with radon.〔()(2, Current Status and Future Perspectives of the COBRA Experiment, J.
