Abstract
Optical clocks have become a very important tool of investigating the characteristics of atoms or ions, for the state-of-art instability and uncertainty. Increasing the running time of an optical atomic clock is one critical issue that scientists are still working on. In this paper we report the improvement of the atomic chamber of a calcium beam optical clock. By using a combination of microtubes as the nozzle, we achieved a very high atomic flux with small divergence. The resonant atomic flux is about 1×1012 to 1013 per second and the divergence is smaller than 30mrad. The experimental results show that the system is reasonable in design and meets the technical indicators.
