Event details
The QUEST-DMC experiment aims to utilise superfluid He-3 instrumented with quantum sensors to access sub-GeV dark matter parameter space. The experiment will have a superfluid He-3 target, operated below 100 microKelvin, contained in cubic cells instrumented with nanomechanical resonators read out by SQUIDs. Superfluid He-3 is a unique system for dark matter searches, with the potential to probe spin-dependent interactions and reach energy thresholds below the eV scale. I will discuss design optimisation and recent developments in nano wire fabrication, bolometric measurements and quantum sensor readout. Simulations of the backgrounds, response model and readout noise, along with the resulting projected dark matter sensitivity, will also be presented.
