Deuterium gas-puff z-pinches are very efficient laboratory sources of neutron pulses. Using a novel hybrid gas-puff load on the GIT-12 generator, a significant increase in the neutron yields up to 5.6 × 10 12 is reached. At the same time, a very broad neutron energy spectrum up to energies on the order of tens of MeV is observed. In these experiments, the neutrons are produced not only by the D(d,n)3He (DD) nuclear reaction but also by reactions of multi-MeV deuterons with the experimental hardware. The angular distribution of the neutron fluence and dependence of the fluence on the distance from the z-pinch are measured using neutron activation diagnostics. By this method, a number of produced non-DD neutrons and anisotropy of DD neutron emission are evaluated.

3 MA 氘气吹 z 夹点实验中的中子注量分布

氘气吹 z 形夹点是非常有效的中子脉冲实验室来源。在 GIT-12 发生器上使用新型混合气体喷气负载，中子产额显着增加，高达 5.6 × 10 12 。同时，观察到高达数十 MeV 量级的非常宽的中子能谱。在这些实验中，中子不仅由 D(d,n)3He (DD) 核反应产生，而且由多 MeV 氘核与实验硬件的反应产生。中子注量的角度分布和注量对距 z 夹点距离的依赖性使用中子活化诊断来测量。通过这种方法，可以评估产生的非DD中子的数量和DD中子发射的各向异性。
