| Abstract: | Ion components,ion charge states and ion diffusion velocities of hydrogen-impregnated-electrode pulsed vacuum arc discharge plasmas were measured by time of flight(TOF) mass spectrometry.The results show that main components of the plasmas are H+,Ti+,and Ti2+,Ti3+,with Ti2+ predominating.The average ion charge of Ti ions is between 1.95 and 2.13 when the discharge current is between 40 A and 80 A,and it increases with the increasing of the discharge current.In addition,different ions have different diffusio... |
