Abstract: Provided is a surface-coated metal porous body having a three-dimensional network structure, the surface-coated metal porous body including: a framework forming the three-dimensional network structure; and a coating film provided on a surface of the framework, wherein the framework has a body including a metal element as a constituent element, the coating film includes a scale-like carbon material and a fine-grained conductive material, a distance D between two points that are farthest from each other on an outer perimeter of a main surface of the scale-like carbon material is 5% or more and 120% or less relative to a thickness of the framework, and the scale-like carbon material is deposited on the surface of the framework.

Abstract: Provided are a long-lived target for a neutron-generating device and a method for manufacturing the target therefore. The target is for a neutron-generating device and includes: a metal substrate retaining a target material; and a metal thin film for sealing that holds the target material at a retention surface X side. The retention surface X side of the metal substrate includes: a frame portion; and an embossed structure including: a plurality of island portions that are surrounded by the frame portion; and the rest recessed portion that is created by decreasing a thickness of a region other than the frame portion and the island portions by a thickness of the target material. The metal thin film and surfaces of the frame portion and the island portions are subjected to hot isostearic pressing (HIP) bonding to seal the target material onto the recessed portion by using the metal thin film.

Abstract: A radioisotope production apparatus includes: a linear accelerator for accelerating an ion beam and irradiating a target with the ion beam, radio frequency power supplies for supplying radio frequency waves through coaxial tubes and the linear accelerator, a target shield member containing the target, a first radiation shield member covering the linear accelerator, and a movable second radiation shield member covering the side of target shield member of the linear accelerator between the first radiation shield member and the target shield member. The first radiation shield member is movably divided in opposite directions, respectively, of the axial direction of the linear accelerator from the base point of the connection point of the coaxial tube connected to the linear accelerator.
