Abstract
We present a new design for a directed high-flux high-temperature atomic vapor source for use in atomic physics experiments conducted under vacuum. An externally heated nozzle made of an array of stainless steel microcapillaries produces a collimated atomic beam. Welded stainless steel construction allows for operation at high source temperatures without exposing delicate conflat vacuum flanges to thermal stress, greatly enhancing robustness compared to previously published designs. We report in operando performance measurements of an atomic beam of lithium at various operating temperatures.
