Abstract
We developed an MMC-based detector system to measure the $^{63}$Ni beta spectrum, with the goal of searching for keV-scale sterile neutrinos. Two identical detectors with gold absorbers of the same size were constructed. One of the absorbers enclosed a small source foil containing radioactive $^{63}$Ni, prepared using an electrochemical deposition procedure developed in this work. An excellent linearity in the energy range of interest up to 70 keV was demonstrated after energy calibration with an Am-241 source. Furthermore, the detector setup with $^{63}$Ni deposition produced an energy spectrum consistent with the expected activity and energy response. The potential of this detector system for a future keV sterile neutrino search is discussed.
期刊介绍：
IEEE Transactions on Applied Superconductivity (TAS) contains articles on the applications of superconductivity and other relevant technology. Electronic applications include analog and digital circuits employing thin films and active devices such as Josephson junctions. Large scale applications include magnets for power applications such as motors and generators, for magnetic resonance, for accelerators, and cable applications such as power transmission.
