Abstract
The atomic frequency standard has a heating element (58) surrounding an enclosure (43) which defines a microwave resonance cavity (42). The heating element supplies heat to an absorption cell (41) located in the cavity. The absorption cell (41) is surrounded by electrodes (45a-45d) which act to enhance and orient the oscillating magnetic field in the region of the absorption cell. Thermally conductive members (47a-47d) connect the electrodes (45a-45d) to the enclosure (43) to better control the temperature of the cell while retaining the advantages due to the presence of the electrodes (45a-45d).
