法国南巴黎大学基础电子学研究所Arditi和Picqué提出了一种新型铯束管的试验报告。看来这可能是新一代铯束管的雏型,值得注意。铯束原子频标是当前用作时间频率基准、并有批量商品生产的、准确度最高的一种频标。由于铯束管制造工艺复杂,商品铯束管至今仍为世界上极少数几家公司所垄断。和传统 Arditi and Picqué, Institute of Basic Electronics, University of Paris, France, presented a new type of cesium tube test report. It seems that this may be the prototype of a new generation of cesium tube, it is noteworthy. Cesium beam atomic frequency standard is currently used as a time frequency base, and a batch of goods produced, the highest accuracy of a frequency standard. Cesium-beam tubes are still monopolized by a handful of companies in the world today because of the complicated manufacturing process of cesium-beam tubes. And tradition
