Abstract

A high flux neutron source based on a vacuum-insulated tandem accelerator (VITA) and a lithium target has been proposed and developed at the Budker Institute of Nuclear Physics in Novosibirsk, Russia. We describe VITA which provides a dc proton/deuteron beam with an energy within a range of 0.6–2.3 MeV with a current from 1 nA to 10 mA. VITA is also capable of producing α-particles through the 7Li(p,α)α and 11B(p,α) α α reactions, 478 keV photons through the 7Li(p,p ′ γ)7Li reaction and positrons through the 19F(p,e+e−)16O reaction. We present several applications of this source: boron neutron capture therapy, nuclear cross sections determination, lithium target study, radiation blistering of metals during proton implantation and the radiation testing of promising materials.

适用于各种应用的VITA高通量中子源

在俄罗斯新西伯利亚的Budker核物理研究所，提出并开发了一种基于真空绝缘串列加速器(VITA)和锂靶的高通量中子源。我们描述了VITA，它提供了一个能量在0.6-2.3 MeV范围内的直流质子/氘核束，电流从1 nA到10 mA。VITA还能够通过7Li(p，α)α和11B(p，α) α α反应产生α-粒子，通过7Li(p,p′γ)7Li反应产生478 keV光子，通过19F(p,e+e−)16O反应产生正电子。我们介绍了该源的几种应用:硼中子俘获治疗、核截面测定、锂靶研究、质子注入过程中金属的辐射起泡以及有前途材料的辐射测试。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
