2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/86976We describe the design of a single beam, multiple species atom source in which the flux of any component can be separately adjusted. Using this design we have developed a 23Na-6Li atom source for ultracold atom experiments. The fluxes of lithium and sodium are independently tunable, allowing operation as a single 23Na or 6Li source as well as a double source with equal atomic fluxes in each component.5 pages, 2 figuresInstrumentation and Detectorstext
