Abstract

Stable neutron generation with a yield of ∼1.2 × 10⁴ neutrons per pulse was obtained during d(d,n)³He reaction initiated by the high-voltage nanosecond discharge in a gap with a potential tungsten cylinder (anode) and a grounded deuterated zirconium plate (cathode) filled with deuterium at a pressure of ∼10² Pa. Estimated duration of the neutron pulse was ∼1.5 ns. Less intensive neutron emission was registered without deuterated plate. Splashing of material of the tungsten electrode was observed during the high-voltage nanosecond discharge in the deuterium, hydrogen, helium and argon at pressures of 10²–10⁴ Pa.

中子在一纳秒内在氘中低压放电

在高压纳秒放电条件下，在钨电极(阳极)和氘填充的接地氘化锆板(阴极)之间的间隙中进行d(d,n)3He反应，获得了稳定的中子生成，产率为每脉冲1.2 × 104中子。中子脉冲的估计持续时间为~ 1.5 ns。在没有氘化板的情况下，记录了较弱的中子发射。在102 ~ 104 Pa的高压条件下，在氘、氢、氦和氩中进行纳秒放电，观察到钨电极材料的溅射现象。
