High Gain, Low Noise, and Long Lifetime MCP Electron Multiplier for Cesium Clock

In this article, the Micro-Channel Plate Electron Multiplier is studied to carry out the microcurrent multiplication process in order to solve the short lifetime problem of the Electron Multiplier of the present Cesium Clock. Based on the current parameters of the Micro Channel Plate Electron Multiplier, the gain is enhanced by selecting the structure parameters and the application of the cascade structure, the noise is reduced by the improvement of the structure and handing procedure, the lifetime is enhanced by optimization of the working parameters, thus a high gain, low noise, and long lifetime Micro-Channel Plate Electron Multiplier is obtained, which could improve the performance of the Cesium Clock for the navigation system.
