Progress Towards HeRALD: The Helium Roton Apparatus for Light Dark Matter

The HeRALD experiment uses the unique properties of superfluid 4He to study dark matter-nucleon scattering in the sub-GeV mass range. This talk will show progress towards the observation of the quantum evaporation signal using an athermal phonon detector and will discuss HeRALD's R&D program with an emphasis on the helium and materials physics to refine the detector and push the nuclear recoil detection threshold as low as possible.
