本文报道了第一次成功地操作的中子干涉仪与一个单独的光束重组晶体。这一结果是一个原理验证演示，表明新一代中子干涉仪和应用是可能的。本文报道了采用分离束重组晶体的中子干涉仪的首次成功运行。这一结果是在格勒诺布尔ILL的中子干涉测量装置S18上通过格勒诺布尔ILL的TU Wien和都灵的INRIM之间的合作实现的。虽然以前的干涉仪是由单晶块加工而成的，但在这项工作中，两个晶体成功地在纳米和皮米尺度上对齐，以获得中子干涉。作为一个决定性的原理验证演示，这为新一代中子干涉仪和令人兴奋的应用打开了大门。
This article reports the first successful operation of a neutron interferometer with a separate beam-recombining crystal. This result is a proof-of-principle demonstration showing that new-generation neutron interferometers and applications are possible. The first successful operation of a neutron interferometer with a separate beam-recombining crystal is reported. This result was achieved 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 have been machined out of a single-crystal block, in this work two crystals were successfully aligned on nanoradian and picometre scales, as required to obtain neutron interference. As a decisive proof-of-principle demonstration, this opens the door to a new generation of neutron interferometers and exciting applications.
