摘要：

An analysis of the major frequency shifts of our optically pumped Cesium beam primary frequency standard is presented, toghether with a description of the most relevant characteristics of the device. The short term frequency stability was measured against a Hydrogen Maser. The square root of the Allan variance sigma(y)(tau) is at present 5.8.10(-13)tau-1/2, with a flicker level at 3.3 . 10(-15). This extremely good frequency stability enables a highly precise analysis of the most important systematic frequency shifts to be performed in a short time. Our first accuracy evaluation results in an uncertainty (1sigma) of 1.1 . 10(-13).
