摘要
The present invention relates to a kind of microwave cavity for atomic frequency standard, which consists of slotted tube, cylindrical cavity body, dielectric ring, heating filament, screw bolt for adjustment of cavity frequency. Its characteristics are listed as follows: 1. There are slots and electrodes at the upside of slotted tube. 2. The slotted tube and the bottom cap of the cavity are made as a whole. 3. The Rb absorption cell is inserted in the slotted tube. 4. The dielectric ring is inserted between the slotted tube and the cylindrical cavity body. 5. There is one or more screw hole in the wall of cylindrical cavity body. 6. One or more screw bolt for adjustment of cavity frequency is installed into the screw hole.
