The plasma and ion source technology group in Lawrence Berkeley National Laboratory is developing advanced, next generation D-D neutron generators. There are three distinctive developments, which are discussed in this presentation, namely, multi-stage, accelerator-based axial neutron generator, high-output co-axial neutron generator and point source neutron generator. These generators employ RF-induction discharge to produce deuterium ions. The distinctive feature of RF-discharge is its capability to generate high atomic hydrogen species, high current densities and stable and long-life operation. The axial neutron generator is designed for applications that require fast pulsing together with medium to high D-D neutron output. The co-axial neutron generator is aimed for high neutron output with cw or pulsed operation, using either the D-D or D-T fusion reaction. The point source neutron generator is a new concept, utilizing a toroidal-shaped plasma generator. The beam is extracted from multiple apertures and focus to the target tube, which is located at the middle of the generator. This will generate a point source of D-D, T-T or D-T neutrons with high output flux. The latest development together with measured data will be discussed in this article.
劳伦斯伯克利国家实验室的等离子体和离子源技术团队正在研发先进的下一代D-D中子发生器。本报告将讨论三项独特的进展，即多级、基于加速器的轴向中子发生器、高输出同轴中子发生器和点源中子发生器。这些发生器采用射频感应放电来产生氘离子。射频放电的独特之处在于它能够产生高原子氢物种、高电流密度以及稳定且长寿命的运行。轴向中子发生器专为需要快速脉冲以及中到高D-D中子输出的应用而设计。同轴中子发生器旨在通过连续波或脉冲运行实现高中子输出，可使用D-D或D-T聚变反应。点源中子发生器是一个新概念，它利用环形等离子体发生器。束流从多个孔中引出并聚焦到位于发生器中间的靶管。这将产生具有高输出通量的D-D、T-T或D-T中子点源。本文将讨论最新进展以及测量数据。
