科学界对中子发生器有相当大的需求，其输出为106-108中子/秒（n/s），可以打开或关闭，发射聚变中子，自校准，并提供便携式操作。基于惯性静电约束（IEC）的中子发生器就是为了满足这一需求而提出的。在IEC装置中，离子束被注入到一个球形真空容器中，容器中装有一组或多组球形线栅。在最里面的网格的中心通过相交的离子束和相关的势阱结构产生的致密等离子体区域中产生高熔合率。在这里，我们描述了一种独特的配置，称为IECGD，其中在一个单一的网格设备中的气体放电作为离子源。在新发现的“星星”放电模式下运行，最大限度地提高了离子的有效栅极传输系数。这种结构提供了一种简单、坚固、低成本的聚变中子源，工作在106 D-D n/s或108 D-T n/s范围内。
There is considerable demand in the scientific community for a neutron generator with an output of 106–108 neutrons/second (n/s) that can be switched on or off, emit fusion neutrons, be self‐calibrating, and offer portable operation. An Inertial Electrostatic Confinement (IEC)‐based neutron generator is proposed to meet these needs.In an IEC device, ion beams are injected into a spherical vacuum vessel containing one or more sets of spherical wire grids. A high fusion rate is generated in a dense plasma region created in the center of the innermost grid by intersecting ion beams and the associated potential well structure. Here, we describe a unique configuration, termed the IECGD, where a gaseous discharge in a single‐gridded device serves as the ion source. Operation in the newly discovered “Star” discharge mode maximizes the effective grid transmission factor for ions. This configuration, then, provides a simple, rugged, low‐cost fusion neutron source, operating in the 106 D‐D n/s or 108 D‐T n/s range....
