论文摘要

我们报告了具有单独的梁重组晶体的中子干涉仪的第一个成功操作。我们通过Tu Wien,Ill Grenoble和Inrim Torino之间的合作,在Grenoble的中子干涉测量学设置S18上实现了这一结果。虽然先前的干涉仪是从单个晶体块中加工出来的,但我们设法根据需要在纳米层和生平的尺度上对齐两个晶体,以获得中子干扰。作为原则演示的决定性证明,它为新一代中子干涉仪和令人兴奋的应用打开了大门。

We report the first successful operation of a neutron interferometer having a separate beam recombining crystal. We achieved this result at the neutron interferometry setup S18 at the ILL in Grenoble by a collaboration between TU Wien, ILL Grenoble and INRIM Torino. While previous interferometers were machined out of a single crystal block, we managed to align two crystals on nanoradian and picometer scales, as required to obtain neutron interference. As a decisive proof of principle demonstration, it opens the door to a new generation of neutron interferometers and exciting applications.
