At ultra-low temperatures (ULT) macroscopic quantum states form, such as superfluids, that have unique potential as quantum sensors for rare interactions. The QUEST-DMC QTFP project is deploying this technology at two sites capable of reaching ULT, Royal Holloway (RHUL) and Lancaster University (ULANC), both members of the European Microkelvin Platform, EMP ( QUEST-DMC employs a superfluid helium-3 target for “laboratory cosmology”, studying phase transitions relevant for understanding inflation and searching for light Dark Matter candidates. The Dark Matter search will be based on a small 3He target constructed as a bolometer. A nanowire sensor will be used to detect the quasi-particles produced when a Dark Matter interaction breaks the fragile 3He Cooper pairs.
