Experiment Studies on the Diffuse Light Cooling by Using Silver Plated Microwave Cavity
The cold atom absorption signal produced by the silver plated microwave cavity is observed, which finishes the last step of the integration of the microwave cavity and the integrating sphere. This setup which doesn′t use reflective material and won′t influence the magnetic field distribution is not only simpler, but also benefit for the signal to noise ratio of the clock signal. Meanwhile, the cooling performances of the cooling microwave cavity are studied with different cooling light injection schemes, diffuse reflective coefficients and apertures. The results show that the scheme of injecting the cooling light from the end surface can get more cold atoms, and the improvement of the reflective coefficient increases the cold atom numbers. Two 10 mm apertures are used in order to take full advantage of cold atoms in the integrating sphere, and the absorption signals for different apertures show that the 10 mm apertures used here won′t affect the cold atom number.
