Abstract

Spin-polarized atomic hydrogen adsorbed on the surface of liquid helium is the most promising candidate for the observation of quantum degeneracy in a two-dimensional Bose gas. In this article we describe our experimental apparatus which is being used to realize this goal. The apparatus employs a system of superconducting and iron magnets to supply electron and proton spin-polarized hydrogen to a cold cell (T ≈ 0.1 K) at sufficient flux to compensate recombination losses and attain the regime of two-dimensional quantum degeneracy. The gas in the cell is probed using light resonant with the Lyman-α atomic transition.
