Abstract

The invention relates to a generation device of a controllable isotopic neutron source. The generation device of the controllable isotopic neutron source comprises an upper sealing barrel, a lower sealing barrel, an adjusting device, a sealing device, a beryllium sheet set and an alpha-particle emission nuclide plating sheet set. The adjusting device comprises a rotary main rod and a rotary handle, wherein the rotary main rod is arranged at the upper end portion of the upper sealing barrel and can rotate on its axis, and the rotary handle is fixed at the top end of the rotary main rod. The sealing device comprises a corrugated pipe and a connecting body, wherein the connecting body comprises a bottom face and a threaded hole, the threaded hole is formed in the bottom face, and an opening of the threaded hole faces upwards. The upper sealing barrel and the lower sealing barrel are in sealed connection, the corrugated pipe is arranged in the lower sealing barrel, an opening in the upper end of the lower sealing barrel is in sealed connection with an opening in the lower end of the upper sealing barrel, and an opening in the lower end of the lower sealing barrel is sealed with the bottom face of the connecting body. The generation device of the controllable isotopic neutron source aims to solve the problem that due to the uncontrollability of the isotopic neutron source, the safety, the motility and the like are poor. Neutrons appear and disappear by controlling two kinds of reactive nuclides to be closed or separated, and the purpose of controllability is achieved.

Description

technical field [0001] The invention relates to the design and manufacture technology of a neutron source in the field of nuclear technology. It specifically involves the design technology of isotopic neutron sources. Background technique [0002] Neutron sources are widely used in both military and civilian fields. The commonly used neutron sources are accelerator neutron source, fission neutron source, silk dense plasma focus neutron source (DPF) and isotope neutron source. The first three types of neutron sources are controllable neutron sources, among which the accelerator neutron source and the fission neutron source have higher neutron flux and higher safety, but their devices are huge and cannot be moved, and are only suitable for use in fixed positions . Although the Dense Plasma Focus Neutron Source (DPF) is controllable, it belongs to the pulsed intermittent working mode. The literature "Evaluation of the Neutron Yield Stability of Pulsed Neutron Sources" (Nucle...
