Abstract :
We have developed an apparatus which allows us to study the interaction of 3He with powder substrates at temperatures down to 50 mK. A Stycast cell has been filled with liquid or solid 3He, at pressures up to 65 bar, confined by fine powder that can be polarized in situ by dynamic nuclear polarization at 2.5 Tesla. A fast and accurate NMR/AFP system has been used to determine relaxation times. Different substrates have been investigated in search for polarizability and a strong enough surface interaction to eventually transmit their magnetization to bulk 3He.
