Computer Simulation of Commercial Optical Pumping Cesium Beam Tubes Parameters

This paper adopts a new method, the parameters of commercial optically-pumped cesium beam tube (OPCBT) are simulated by computer. We focus on flow and distribution of cesium atoms ejected from the cesium oven of OPCBT, point out the quantitative relationship among the oven temperature, the amount of cesium atoms and the life of cesium beam tube, which provides a theoretical basis for the design of OPCBT structure. At the same time, 3D modeling is carried out, the C-field distribution and microwave field distribution are simulated by computer, which is helpful to understand the relevant parameters intuitively.
