Design of a system for controlling a levitating sphere in superfluid 3He at extremely low temperatures

Abstract We present a new mechanical probe to study the properties of superfluid 3He at microkelvin temperatures down to 100 μK. The setup consists of a set of coils for levitating a superconducting sphere and controlling its motion in a wide variety of regimes. In particular, the realisation of mot...
