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 liquid N2 cooling to LHe cooling the source and demonstrate that LHe cooling offers a significant increase in performance.
