We plan to exploit the outstanding performance features of the Lancaster Advanced Microkelvin Refrigerator, now fully operational, to study the physics of the quantum fluid superfluid helium-3 as well as to continue leading-edge development of ultra-low temperature techniques for experiments in condensed matter physics. Superfluid helium-3 is a model substance with connections to such topics as superconductivity and cosmology. Since we can maintain helium temperatures below 150 microkelvin for at least a week at a time, we can plan sophisticated experiments at the lowest available temperatures, including:(1) to continue and extend measurements on superfluid helium-3 in the material aerogel, which acts as a type of impurity in the helium. We have recently discovered a new method, using an aerogel-loaded vibrating wire device, of studying the superfluid density in this interesting superfluid, and we have discovered an A-B transition.(2) to investigate quasiparticle scattering properties from a bulk superfluid - aerogel superfluid interface.(3) to further investigate the alarmingly long (up to 2000 seconds) spin precession states in bulk superfluid helium-3 using NMR techniques.
