小型密封稠密等离子体焦点中子源

A Compact Sealed Dense Plasma Focus Neutron Source

分析了全密封稠密等离子体焦点(DPF)中子源的特点,采用一维雪耙动力学模型对等离子体的运动进行了计算,设计了相应的电极尺寸和形状,并针对密封性要求,确定了相应的结构和真空处理工艺方法。密封DPF腔体的尺寸为26mm×100mm,在280J下,每脉冲中子产额可达105。

The performance of sealed dense plasma focus (DPF) tube was discussed. The movement of plasma player was simulated using 1-dimension snow-plough dynamics model, and the size and the shape of the electrodes were chosen. For the sealed tube, the special configuration and the vacuum processing were investigated. The sealed DPF tube, 26 mm×100 mm, can yield 10^(5) neutrons per pulse, with the power of 280 J.
