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 …
Welcome to the Official COBRA Webpage
COBRA - the Cadmium Zinc Telluride 0-Neutrino Double-Beta Research Apparatus. More than 60 years have passed since the experimental detection of the neutrino. And yet, some of its properties still remain unknown. The most pressing question probably is the one after the value of the particle's rest mass.
COBRA Experiment
The COBRA experiment uses CdZnTe (CZT) semicon-ductors to search for 0νββ [6]. CZT contains nine double beta emitters, five of which can decay via double beta de-cay, i.e. emitting two electrons, and four of them via ei-ther double electron capture, a combination of a positron emission with electron capture or double positron emis-sion.

The COBRa study, conducted as part of ESA´s SysNova technology assessment scheme, investigated an active debris removal concept relying on the exhaust plume of a monopropellant chemical propulsion system …

Pulse-shape studies with coplanar grid CdZnTe detectors and searches for rare nuclear decays with the COBRA experiment
The Neutrinoless Double Beta Decay
This - basically the simultaneous occurrence of two ordinary β decays - is called double beta decay (2νββ decay). This exotic process was first discussed in 1935 and after that it took 50 years until its first observation in 1987, where the 2νβ - β - decay of the isotope 82 Se was measured.
Current Status and Recent Results of the COBRA Experiment
The COBRA experiment is aiming to use a large amount of CdZnTe semiconductor detectors to perform a search for various double beta decay modes. The current status of the experiment and first results are presented.
The COBRA Experiment
experiment: • Natural radioactivity • Cosmogenic backgrounds • See Ben’s talk for more detail • Neutrons • Muons • See Danielle’s poster for more detail •2νββ decays
The COBRA experiment
The COBRA experiment aims to use a large array of CdZnTe semiconductor detectors to search for neutrinoless double beta decay. The COBRA collaboration are currently operating a small proto-type array of crystals in a low-background environment.
The Current Setup
To investigate the prospects of such an experiment, to gain knowledge about how to work with the detectors, what problems might occur and how to overcome them, it was started to build a smaller version of the proposed experiment in 2011, the COBRA demonstrator.
