Experimental comparison of performances of ultracold neutron gravity spectrometer

对落聚焦型超冷中子重力谱仪的测试实验进行了模拟分析，并与另一种长距聚焦型超冷中子重力谱仪的测试结果进行了比较。首席研究员内郎教授拜访了合作者罗得岛大学的Steyerl教授，讨论了这些重力分光仪的使用和比较实验。此外，劳厄-朗之万研究所的当地联系研究员德雷克塞尔博士应邀前往KURRI，在ILL讨论和准备这些比较实验。

Numerical calculations on the simulation analyses were carried out concerning the test experiments of the ultracold neutron gravity spectrometer of fall-focusing type and comparisons of the results reported on the other type of reach focusing gravity spectrometer. The head researcher Prof. Utsuro visited the collaborator Prof. Steyerl at the University of Rhode Island for discussions on the utilization and comparison experiments of these gravity spectrometers. Further, the local contact researcher of the Institut Laue-Langevin, Dr. Drexel, was invited to KURRI for the discussions and preparations of these comparison experiments at ILL.
