Efficient loading of a He* magneto-optic trap using a liquid He cooled source

Swansson, J. A.; Dall, R. G.; Truscott, A. G.


We report loading large numbers (up to 3×10⁹) of metastable triplet helium atoms into a magneto-optical trap using an atomic beam derived from a liquid He (LHe) cooled dc discharge source. Moreover, we compare the effect of liquidN₂ cooling to LHe cooling the source and demonstrate that LHe cooling offers a significant increase in performance.
