Demonstration of focusing by a neutron accelerator

Abstract

Space-time focusing was demonstrated by a neutron accelerator. Test experiments were performed by using very slow neutrons at High-Flux Reactor at Institut Laue-Langevin. Focusing of neutrons at the detector position through the accelerator was observed. Focusing neutrons enables us to transport the neutrons while maintaining density from source to experimental position. This will be a powerful technique for measurement of the permanent electric dipole moment of neutrons, which require a high density of neutrons.
