摘要：

Two novel devices for use in neutron imaging technique are introduced. The first one is a high-performance optical lens for video camera systems. The lens system has a magnification of 1:1 and an F value of 3. The optical resolution is less than 5 mu m. The second device is a high-resolution fluorescent plate that converts neutrons into visible light. The fluorescent converter material consists of a mixture of (LiF)-Li-6 and ZnS(Ag) tine powder, and the thickness of the converter is material is as little as 15 mu m. The surface of the plate is coated with a 1 mu m-thick gadolinium oxide layer. This layer is optically transparent and acts as an electron emitter for neutron detection. Our preliminary results show that the developed optical lens and fluorescent converter plates are very promising for high-resolution neutron imaging. (C) 2013 The Authors. Published by Elsevier B.V.
