A compact, portable rubidium atomic beam clock based on lamp-pumping and fluorescence-detection scheme is proposed. The expected short-term frequency stability can be at least three orders of magnitude better than that of previous experimental results. The usages of lamp pumping, fluorescence detection and microwave slow-wave resonance structures make this design robust and compact. [DOI: 10.2971/jeos.2011.11005

A compact, portable rubidium atomic beam clock based on lamp pumped and fluorescence detection scheme is proposed. The expected short-term frequency stability can be more than two orders of magnitude better than previous experimental results. The usages of lamp pumping, fluorescence detection and microwave slow-wave resonance structures make this design robust and compact. The shortcomings will be discussed too.
