中子超级镜已成为传输、弯曲和聚焦中子束的重要装置。为了生产这些器件，日本原子能机构安装了有效沉积面积直径为 500 匝的离子束溅射 (IBS) 设备。已制造出高反射率的 Ni/Ti 超级镜，其反射率高达镍临界边缘的 m=3、4 和 6.7 倍。它们在有效临界动量传递时的反射率分别为 0.82、0.66 和 0.23。 (c) 2006 Elsevier B.V. 保留所有权利。
Neutron supermirrors have become important devices for transporting, bending, and focusing neutron beams. For the production of these devices, an ion beam sputtering (IBS) apparatus with an effective deposition area whose diameter is 500 turn has been installed in the Japan Atomic Energy Agency.Ni/Ti supermirrors have been fabricated with high reflectivity extending up to m=3, 4, and 6.7 times the critical edge of nickel. Their reflectivities at the effective critical momentum transfer were 0.82, 0.66, and 0.23, respectively. (c) 2006 Elsevier B.V. All rights reserved.
