Neutron and Ion Production with Various Applied Voltages in Spherical Plasma Focus

Abstract

In this work, the applied voltage effect on neutron yield and ion production are studied by varying thecharging voltage between 15 kV and 30 kV with 1 kV increment to investigate neutron yield, radiationemissions and ion properties using the developed MHD model. While Joule heating, radiativerecombination, bremsstrahlung and line radiation are calculated as radiation terms, beam-ion speed, energyand density are calculated as ion properties. The dominant neutron production mechanism is beam-targetwhich results from the accelerated energetic ions under the diode voltage which is calculated along withneutron yield. In this study, while maximum neutron yield is 2.63 1013 for 30 kV charging voltage, beamion energy and speed reach 61 keV and 240 cm/µs, respectively.
