Sample Preparation and Gamma-Assay Measurements at the Low-Background Counting Facility at the Kimballton Underground Research Facility

ORAL

Abstract

The KURF (Kimballton Underground Research Facility) is home to a gamma counting facility, consisting of two HPGe (high purity germanium) detectors specifically designed for low background assay work. We will discuss the techniques and sample preparation done for gamma-assay at this facility. Specifically we will discuss the gamma-assay measurements done for Axon PicoCoax cable which is a possible candidate for the M\textsc{AJORANA} D\textsc{EMONSTRATOR}. We will also discuss the gamma-assay measurements for lead bricks from Sullivan lead that are to be used for shielding in MALBEK (The M\textsc{AJORANA} Low Background BEGe Detector at KURF) and the proposed M\textsc{AJORANA} experiment.
