The design details and performance characterization results of a newly developed plasma focus based compact and portable system (0.5 m × 0.5 m × 1.2 m, weighing ≈100 kg) that produces an average neutron yield of ~2 × 10 8 neutrons/shot (of fast D-D neutrons with typical energy ~2.45 MeV) at ~1.8 kJ energy discharge are reported. From the detailed analysis of the experimental characterization and simulation results of this system, it has been conclusively revealed that specifically in plasma focus devices with larger static inductance: (i) pinch current is a reliable and more valid neutron yield scaling parameter than peak current, (ii) the ratio of pinch/peak current improves as static inductance of the system reduces, (iii) the benign role of the higher static/pinch inductance ratio enables the supply of inductively stored energy in densely pinched plasma with a larger time constant and it is well depicted by the extended dip observed in the discharge current trace, (...

紧凑型基于等离子体焦点的便携式快速中子发生器的研制与性能表征

新开发的基于等离子体聚焦的紧凑便携式系统（0.5 m ×  0.5 m  ×  1.2 m，重约100 kg）的设计细节和性能表征结果 ，产生的中子平均产量约为2  × 据报道，在约1.8 kJ的能量放电下，每发子弹有10 8个中子（典型能量为〜2.45 MeV的快速DD中子）。从对该系统的实验特性和仿真结果进行的详细分析，可以得出结论，特别是在具有较大静态电感的等离子聚焦装置中：（i）夹点电流是比峰值电流可靠且更有效的中子产率定标参数， （ii）夹点/峰值电流之比随着系统的静态电感的减小而提高，（iii）较高的静态/夹点电感比的有益作用使得能够以较大的时间常数在密集压缩的等离子体中提供感应存储的能量，以及通过在放电电流曲线中观察到的扩展跌落可以很好地描绘出该现象（...
