In this study, neutron production characteristics were investigated by employing three different anode designs. Previously, Takao et al. in Plasma Sour Sci Technol 12:407, (2003) studied the effect of anode design on the production of impurity ions i

The results of an experimental study of pre-ionization and heavy gas introduced into driven gas in a plasma focus device are reported. To achieve this purpose, we made use of two methods: first, the pre-ionization method by applying the shunt resisto

In order to understand the heating process during proton–boron11 ( P – B 11 ) fusion in a high density pinched plasma, we investigate the coalescence of two current loops, consisting of two ion species (protons, boron), using an electromagnetic r

Neutron production mechanisms in a medium energy plasma focus device (20 kJ) were investigated. The time-resolved hard X-ray, neutron signals were obtained with two detectors based on a plastic scintillator–photomultiplier combination located at tw

In this research, the effects of pre-ionization using a shunt resistor on reproducibility of x-ray emission in a Mather type plasma focus device have been studied. This technique increased the intensities of the emitted x-rays from argon as the filli

This paper reports some of the results that are aimed to investigate the neutron emission from the middle energy Mather‐type plasma focus. These results indicated that with increase the pressure, compression time is increase but there is not any di

Impurities produced by the vaporization of metals in the electrodes may be a major cause of reduced fusion yields in high-current dense plasma focus devices. We propose here that a major, but hitherto-overlooked, cause of such impurities is vaporizat
