Description

The Helium Roton Apparatus for Light Dark Matter (HeRALD) experiment will use superfluid 4He to probe unexplored dark matter parameter space. Superfluid helium has several advantages: good kinematic matching to light dark matter candidates, ballistic quasiparticle propagation, scalability, and multiple signal channels for electronic vs. nuclear recoil discrimination. I will discuss recent progress by the TESSERACT collaboration to develop this technology, including work done at LBNL, UC Berkeley, and UMass Amherst. I will focus on detector development and instrumentation.
