项目摘要

The purpose of the present research is to carry out the experimental comparison of the performances of two ultracold neutron gravity spectrometers, one is now working at the Institut Laue Langevin with the principle of reach focusing of neutrons, and the other is the improved version developed by the group of the present applicant with the principle of the fall focusing of scattered neutrons.As the first step of the present international collaboration for the experimental comparison, the head investigator visited the University of Rhode Island to discuss with Prof. Albert Steyerl who invented and completed the reach focusing gravity spectrometer named NESSIE, and obtained much instructive indications concerning the very high energy resolution, focusing properties of neutrons and several conditions on the scattering samples for the gravity spectrometers of ultracold neutrons. The agreement among us was also derived that our experiment for the comparisons of performances should bec arrie … More d out at the ultracold neutron facility of the Institut Laue Langevin.In the next place, further details of the working conditions of NESSIE were investigated by Mr. T. Ebisawa who visited the Institut Laue Langevin and discussed actively with Dr. W. Drexel, the responsible staff on these ultracold neutron facilities. Several important conclusions and precautions werederived through these investigations concerning especially the scattering sample and related conditions for the experiment using the gravity spectrometer.Further, some preliminary preparations were progressed by Dr. Y. Kawabata who also visited the Institut Laue Langevin and the experimental location for our new gravity spectrometer, named SUPERNESSIE by Dr. Drexel, to carry out performance tests and demonstrations was assigned. The gravity diffractometer which occupying now the location assigned is in the course of the final stage of the experimental research and therefore it will be replaced to our supernessie in near future according to our research program.

本研究的目的是对两个超声器中子重力光谱仪的表现进行实验比较，一个现在正在研究所Laue Langevin研究中，其原则是中性子的重点，而另一个是由当前的散布中子的偶然性访问的主要范围的范围的范围进行的，是由本次数的逐步进行的。罗德岛（Rhode Island）与阿尔伯特·史蒂耶尔（Albert Steyerl）教授讨论，他发明并完成了名为Nessie的触及聚焦重力光谱仪，并获得了有关非常高能量分辨率的启发性的指示，中子的聚焦特性以及在超级中子的重力光谱仪的散射样品上的多个条件。 The agreement among us was also derived that our experiment for the comparisons of performances should bec arrival … More d out at the ultracold neutron facility of the Institut Laue Langevin.In the next place, further details of the working conditions of NESSIE were investigated by Mr. T.
