Experimental study on discharge characteristics of a subnanosecond high pressure N_2 switch
Experimental study on discharge characteristics of high pressure subnanosecond N_2 switch was carried out by using a high voltage nanosecond generator in the article. The results show that when N_2 pressure ranges from 3 to 10 MPa and gap distance ranges from 0.6 to 1.2 mm, the breakdown voltage of N_2 gap increases as N_2 pressure and gap distance increases, and saturates as N_2 pressure increases. The highest breakdown electric field is about 2 MV/cm. The rise time of the output voltage of the high pressure subnanosecond N_2 switch ranges 145~190 ps, and decreases as N_2 pressure and gap distance increases.
