Research Abstract

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.
