Abstract

Potassium-40 (⁴⁰K) is a background in many rare-event searches and may well play a role in interpreting results from the DAMA dark-matter search. The electron-capture decay of ⁴⁰K to the ground state of ⁴⁰ Ar has never been measured and contributes an unknown amount of background. The KDK (potassium decay) collaboration will measure this branching ratio using a ⁴⁰K source, an X-ray detector, and the Modular Total Absorption Spectrometer at Oak Ridge National Laboratory.

Funding

Paul Davis designed and supplied the APD electronics through the NSERC/University of Alberta MRS. Engineering support has also been contributed by Miles Constable and Fabrice Rétière of TRIUMF, as well as by Koby Dering through the NSERC/Queen’s MRS. Work was performed at Oak Ridge National Laboratory, managed by UT-Battelle, LLC, for the U.S. Department of Energy under Contract DE-AC05-00OR22725. Thermal deposition was conducted at the Center for Nanophase Materials Sciences, which is a DOE Office of Science User Facility. Funding in Canada has been provided by NSERC through SAPIN and SAP RTI grants. Support has also been supplied by the Joint Institute for Nuclear Physics and Application.
