Improving cryogenic buffer-gas beam collimation with de Laval nozzles

ORAL

Abstract

Cryogenic buffer-gas beam sources produce extremely high fluxes of cold molecular radicals. By using a converging-diverging nozzle, we have observed improved collimation and higher fluxes per solid angle. The beam properties were tested with atomic titanium and ytterbium; progress towards producing guided beams of CH radicals will be discussed.
