Ultra-low Background Detectors


Many experiments conducting a direct search for dark matter require that the detector elements and the surrounding support materials exhibit extreme radiological stability. The presence of trace amounts of radioactivity in or near a detector induces unwanted effects. These elements could include: 1) Ultra-low-background neutron and alpha-particle detectors. 2) Development of ultra-radio-pure material for use in detectors. 3) Manufacturing methods of ultra-low- background materials.
