Abstract :The effect of the cathode radius variation insert ignore into journalissuearticles values(from 11.5 cm to 17 cm); on neutron yield, discharge current, plasma temperature, and ion properties insert ignore into journalissuearticles values(velocity, energy, and density); are investigated in this study using the developed spherical plasma focus model and the results are reported in this paper. Peak discharge current and peak beam-ion properties decrease with increasing the cathode radius. Maximum plasma temperature insert ignore into journalissuearticles values(22.34 eV); and maximum beam-target neutron yield insert ignore into journalissuearticles values(1.18×1013); are achieved using the cathode with 15 cm radius. The longest pinch duration for all calculations is also achieved using 15 cm cathode radius. It is found that the optimum cathode radius is 15 cm in terms of the neutron yield, plasma temperature and beam-ion properties in spherical plasma focus device.
