Numerical Experiments on IR-MPF-100 Plasma Focus Operated in Neon and Deuterium Gases

In this paper, using the current fitting method, the Lee model parameters are computed for the IR-MPF-100 plasma focus (maximum energy ～115 kJ) operated in the neon and deuterium gases and the results are presented in the different operational conditions. The values of f_c, f_cr and f_mr were obtained 0.43, 0.55 and 0.05 respectively for the neon gas in all values of pressure and voltage. f_m varies as a function of pressure and voltage. f_m varies from 0.03 to 0.04 for 23.3 kJ of energy and it is almost constant equal to 0.024 for 10.2 kJ of energy. In the case of deuterium gas, f_c and f_cr are found 0.3 and 0.4 respectively. In this case, ({text{f}}_{text{m}}) varies between 0.028 and 0.1 and f_mr varies between 0.05 and 0.20. It is noted that in the case of deuterium gas, f_m and f_mr decrease with the pressure increasing approximately and in the case of neon gas f_m increases with pressure increasing. So we calculate neutron yield and soft X-ray yield using the Lee model code for the different operational conditions.
