A compact sealed dense plasma focus neutron source

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, φ26 mm x 100 mm, can yield 105 neutrons per pulse, with the power of 280 J. (authors)
