Abstract

Summary form only given. A second POS (plasma opening switch) stage is proposed to increase the output pulse parameters of the GIT-4 generator, provided the first POS stage gives rapid current input (in about 100 ns) in the second POS stage. The latter can be designed with diminished inner electrode diameter to achieve rapid opening. Experiments have shown that the dR_s/dt (where R_S is the switch resistance) of the second stage is about 100 times higher than that of the first stage. To measure the output voltage two techniques were used: a 3-m-long vacuum coaxial line (VCL) and p-i-n-diode X-ray measurements. It was found that the voltage pulse on the 30-Ω electron diode load rises in about 10 ns up to 4 (p-i-n) to 5 (VCL) MV
