We demonstrate position and energy-resolved phonon-mediated detection of particle interactions in a silicon substrate instrumented with an array of microwave kinetic inductance detectors (MKIDs). The relative magnitude and delay of the signal received in each sensor allows the location of the interaction to be determined with < 1 mm precision at 30 keV. Using this position information, variations in the detector response with position can be removed, and an energy resolution of \sigma_E = 0.55 keV at 30 keV was measured. Since MKIDs can be fabricated from a single deposited film and are naturally multiplexed in the frequency domain, this technology can be extended to provide highly-pixelized athermal phonon sensors for ~1 kg scale detector elements. Such high-resolution, massive particle detectors would be applicable to next-generation rare-event searches such as the direct detection of dark matter, neutrinoless double-beta decay, or coherent neutrino-nucleus scattering.

  1. Broadband phonon production from axion absorption

    hep-ph 2024-11 conditional novelty 7.0 of 10

    Random nuclear spin orientations break momentum conservation, so axion absorption in crystals excites phonons across the whole Brillouin zone, yielding a broadband detection rate proportional to the phonon density of states.

  2. CUPID pre-CDR

    CUPID proposes a large bolometric detector array with alpha/beta discrimination to achieve a background-free search for 0νββ decay in 100Mo and probe the inverted neutrino mass hierarchy.
