A silicon photomultiplier maintains single-photon response and measurable gain at 9.4 mK with characterized dark-count and correlated noise, enabling proof-of-concept scintillator readout for cryogenic muon vetoes.
A hermetically sealed xenon heat pump demonstrator provides 118 W cooling and 121 W heating at 386 W electrical input, sufficient for 3.1 kg/h xenon purification flow and far below the 6 kW of existing helium-based systems.
A 0.233 g silicon athermal phonon detector with 361.5 MeV/c² rms resolution sets the strongest direct-detection limits on dark matter-nucleon cross sections for masses 44–87 MeV/c² after 12 hours of exposure.
Xe-125 positron decay branching ratio measured as 0.29% at 5.5 sigma significance, providing the first constraint on individual levels in I-125.
