Research Abstract

Neutron beam focusing devices are indispensable in neutron scattering facilities to meet demands for various areas such as powder diffraction experiments under extreme pressure and so on. A spheroidal supermirror with multi-channel substrates has been developed using an ion beam sputtering instrument that can good quality layers with a large critical angle and using numerically controlled local wet etching(NC-LWE) process which can fabricate the elliptical substrate with the figure accuracy of micrometric level.
