Title: Low-Background Searches for Rare Events: The MAJORANA Neutrinoless Double-Beta Decay Experiment


Rare event searches will have a strong impact on the search for physics beyond the Standard Model in the coming years. One field in which this is particularly true is in searches for neutrinoless double-beta decay. For this seminar, we will focus on the MAJORANA experiment which will search for neutrinoless double-beta decay in 76Ge by constructing an array of HPGe detectors in ultra-clean electro-formed copper cryostats deep underground. Recent advances in HPGe detector technology, particularly the development of P-type Point Contact (PPC) detectors, present excellent new opportunities in identifying and reducing backgrounds to the double-beta decay signal. We will present an overview of the MAJORANA experimental program as well as highlight recent R&D progress related to detector and cryostat designs.
