摘要:

在巴黎的BNM SYRTE实验室,两个133 Cs喷泉和一个87 Rb喷泉已经得到了验证。本文介绍了在同一结构内实现87 Rb和Cs双喷泉同时工作的结构。到目前为止,只有Cs部分正在运行,但Rb部分已经完成,不久将投入运行。该实验已被预测,以改善目前的喷泉频率标准,并进行更精确的实验室测试(在10 E-16水平)的精细结构常数α的可能的时间变化,作为最近的宇宙学证据强烈的动机。

英文摘要:

At BNM-SYRTE laboratories in Paris two 133Cs fountains and a 87Rb one have been already demonstrated. This paper illustrates the construction of a 87Rb and Cs dual fountain realized within the same structure to work simultaneously. Up to now only the Cs part is under operation but Rb part, already completed, will be soon operational. The experiment has been projected to improve present fountain frequency standards and to perform a more precise laboratory test (at 10E-16 level) on a possible time variation of the fine structure constant alpha, as recent cosmological evidences strongly motivates.
