Overview
We realize a continuous, high flux, cold molecular or atomic beam using buffer gas cooling techniques. Recent efforts have focused on creating such a source by mixing hot vapor (up to 600K) with cold neon buffer gas (15K) before emitting the mixture in a high flux beam. Neon buffer gas produces a beam with a forward velocity distribution and low energy tail comparable to much colder helium based beams. Such a beam may be a good starting point for laser cooling, cold collision studies, and trapping . Recent efforts have focused on magnetic trapping of potassium, but previous work realized cold beams of molecular oxygen and deuterated ammonia molecules.
