Abstract

The elusive Dark Matter (DM), proposed due to its gravitational interaction with ordinary matter, supposedly makes up ∼ 25 % of our universe’s energy content. Various models aim to explain the origin and properties of DM, many of these proposing beyond standard model particles. It is foreseen that the ALPS II (Any Light Particle Search II) light-shining-through-walls experiment will use NIST Transition Edge Sensors (TESs) to detect low-energy single-photons originating from axion(ALP)-photon conversion with rates as low as 10−5 s−1. Even beyond ALPS II, these superconducting microcalorimeters, operated at cryogenic temperatures, offer an approach to search for another class of particle-DM candidate. Much of the work to ensure the viability of the TES detector for use in ALPS II, such as calibrating the detector and mitigating external sources of backgrounds, also leads to the ability to utilize the TES for an independent direct-DM search. For this purpose, the superconducting sensor, sensitive to sub-eV energy depositions, can be used as a simultaneous target and sensor for DM-electron scattering for sub-MeV DM.
