Abstract
The invention discloses a physical system of strontium optical clock applied for space station, relating to the field of optical atomic clocks, comprising a special-shaped cavity and a MOT cavity. A Zeeman slower is arranged between the special-shaped cavity and the MOT cavity, and the special-shaped cavity and the MOT cavity are provided with a plurality of interfaces that communicate with their interiors; an internal heating atomic oven is arranged in the special-shaped cavity, and an anti-Helmholtz coil and a remanence compensation coil are arranged on the outer wall of the MOT cavity; the two cavities are both connected with a vacuum device for forming a vacuum, and both the special-shaped cavity and the MOT cavity are provided with optomechanical components. The system integrates the internal heating atomic oven in the special-shaped cavity to reduce the space occupied by the heating atomic oven.
