【摘要】 为解决我国自己研制的商品铯钟寿命短、至今不能投入实际使用的问题,本文提出用场效应管高阻放大器代替铯束管中使用的电子倍增器、用动态型六极束管代替密封型二极束管的解决办法。采用此方案后,预期可得到主要技术指标与现行商品铯钟相近、但其具有较长寿命、尤其适用于守时的商品铯钟。更多还原

【Abstract】 The living-time of the commercial cesium atomic clocks made in China is short,and they havn’t bean used in practical operation untill recent.In order to solve this problem,the artical proposes a method of that thehigh impedance amplifier takes the place of the electro multiplier in cesium beam tube,and that the continuesly pumping hexapole tube repla cesthe sealed dipole tube.By means of that,they are able to obtain the main technical performance which approaches that of the current comme- rcially useful for keeping-time.更多还原
