马约拉纳大学正在位于美国南达科他州铅市霍姆斯塔克金矿的桑福德地下研究设施建造马约拉纳演示器。该装置将使用富含同位素76Ge的Ge探测器，以证明大规模Ge探测器实验寻找无中微子双β衰变的可行性。这种假设过程的半衰期很长，要求仪器中的放射性同位素含量极低，因为放射性同位素的衰变可能会给搜索带来背景。由合作进行的放射性测定程序，以确保组成该装置的材料是足够纯的描述。从γ射线计数，中子活化和质谱的放射性同位素污染的研究用于在探测器中使用的材料的测量结果的报告。我们在实验预期背景的背景下解释这些数字。
TheMajoranacollaboration is constructing theMajorana Demonstratorat the Sanford Underground Research Facility at the Homestake gold mine, in Lead, SD. The apparatus will use Ge detectors, enriched in isotope76Ge, to demonstrate the feasibility of a large-scale Ge detector experiment to search for neutrinoless double beta decay. The long half-life of this postulated process requires that the apparatus be extremely low in radioactive isotopes whose decays may produce backgrounds to the search. The radioassay program conducted by the collaboration to ensure that the materials comprising the apparatus are sufficiently pure is described. The resulting measurements from gamma-ray counting, neutron activation and mass spectroscopy of the radioactive-isotope contamination for the materials studied for use in the detector are reported. We interpret these numbers in the context of the expected background for the experiment.
