DESCRIPTION:Speakers: Elizabeth Leason\n\nSuperfluid helium-3 bolometers c
 an exploit the extremely low superfluid gap (10-7 eV) to give ultra-low en
 ergy threshold dark matter direct detection searches. This gives the poten
 tial to probe dark matter models with sub-GeV/c2 masses\, in particular of
 fering world-leading sensitivity to spin-dependent interactions. Realising
  this requires operation at ultra-low temperatures in the 100s uK regime\,
  where helium-3 in the B phase has extremely low specific heat\, coupled w
 ith low noise detector readout. QUEST-DMC measurements of quasiparticle de
 nsity in superfluid helium-3\, using novel vibrating wire resonators and S
 QUID readout\, will be presented. I will show resonator characterisation\,
  energy calibration strategies and multiple resonator readout schemes\, in
  addition to recently measured energy spectra in comparison with Monte Car
 lo simulations.\n\nhttps://indico.global/event/15075/
