The MAJORANA collaboration is constructing the DEMONSTRATOR, an ultra-low background array consisting of 40 kg of germanium detectors, at least half of which will be enriched to 86% in 76Ge. The primary goal is to show the feasibility for a tonne scale search for neutrinoless double-beta decay. With its low energy threshold, the array will also be able to search for light WIMP dark matter. The DEMONSTRATOR will utilize p-type point contact detectors which offer attractive features including low-energy (sub keV) thresholds and superior pulse shape discrimination of multisite events. Recent measurements from CoGeNT and MALBEK, a prototype detector for MAJORANA, will be discussed.
