Germanium Isotopic Measurements for MAJORANA


EMSL Project ID
38791

Abstract

The current focal point of PNNL's weak interaction physics program is the MAJORANA Demonstrator, and the follow-on 1-tonne scale experiment, a large array of ultra-low background high-purity germanium detectors, enriched in 76Ge, designed to search for zero-neutrino double-beta decay (0vbeta-beta). This experiment requires the use of germanium isotopically enriched in 76Ge. Samples of separated material require analysis to determine the amount of each isotope of germanium in the sample (isotopes 70, 72, 73, 74, 76 are stable). This is a DOE and NSF funded project with a major science impact. EMSL has the required instruments for making these measurements.
