【Abstract】 In order to validate the rationality and validity of our experimental setup,a theoretical model of plasmas balance_pinch was built using the basic principle of plasmas pinch_effect. The pinch current was computed when the capillary was filled with 80 Pa Ar and the result is very meaningful to the discharge experiment made with capillary discharge setup. The experimental results show that the maximal discharge current is 30.4kA when the direct current high voltage of Marx generator is 190kV. The discharge current estimated is over 40kA when he maximal output voltage of Marx generator is 300kV.更多还原
