Abstract
In this paper, the design and performance of a collimated Knudsen source, which has the benefit of a simple design over recirculating sources, is discussed. Measurements of the flux, transverse velocity distribution, and brightness of the resulting rubidium beam at different source temperatures were conducted to evaluate the performance. The scaling of the flux and brightness with the source temperature follows the theoretical predictions. The transverse velocity distribution in the transparent operation regime also agrees with the simulated data. The source was tested up to a temperature of 433 K and was able to produce a flux in excess of 10(13) s(-1).
