氘氚基反应脉冲中子发生器被封装在宽1.54 cm（0.600 in）、长3.175 cm（1.25 in）、厚0.3 cm（0.120 in）的扁平计算机芯片中，在0.5 μs脉冲内每脉冲（14 MeV）产生103个中子。中子发生器是基于氘离子束加速撞击氚负载的目标。加速电压在15至20 kV范围内，间隙为3 mm（0.120英寸），通过使用透镜设计对离子束进行整形，以产生符合平坦矩形目标的平坦离子束。离子源是一个简单的表面安装的氘填充钛膜，具有熔融间隙，在电流-电压设计下工作，在约1 μs的脉冲长度内释放氘。我们提出了一些初步的结果和工作原型的一般描述，我们已经标记为“中性”。
A deuterium-tritium base reaction pulsed neutron generator packaged in a flat computer chip shape of 1.54 cm (0.600 in) wide by 3.175 cm (1.25 in) long and 0.3 cm (0.120 in) thick has been successfully demonstrated to produce 103 neutrons per pulse (14 MeV) in a 0.5- μs pulse. The neutron generator is based on a deuterium ion beam accelerated to impact a tritium-loaded target. The accelerating voltage is in the 15- to 20-kV range with a 3-mm (0.120 in) gap, and the ion beam is shaped by using a lens design to produce a flat ion beam that conforms to the flat rectangular target. The ion source is a simple surface-mounted deuterium-filled titanium film with a fused gap that operates at a current-voltage design to release the deuterium during a pulselength of about 1 μs. We present some of the preliminary results and the general description of the working prototypes, which we have labeled the “NEUTRISTOR.”
