Multiple species atom source for laser-cooling experiments

We 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 Na23–Li6 atom source for ultracold atom experiments. The fluxes of lithium and sodium are independently tunable, allowing operation as a single Na23 or Li6 source as well as a double source with equal atomic fluxes in each component.
