Design and experimental investigation of compact pulsed power source based on Kapton-film dielectric line

In the paper, a compact pulsed power source based on dielectric line is designed, with the output power more than 4 GW, pulse width 150 ns, and total volume 0.5 m3. The pulsed power source adopts module design, and it is composed of the charring unit, the dielectric line modules and the switches. The energy is stored in Kapton film of the dielectric line. To repress the electromagnetic coupling and take into consideration of the surface insulation, 30 mm is chosen for the distance between two adjacent turns. The height of switch is 45 mm after optimization, with the inductance of which 16.2 nH. In order to decrease the inductance of the system, the connecting electrodes of the dielectric line module are pressed within the switchs electrode. The insulator within the electrodes is 60 layers of Kapton dielectric film, whose total thickness is 2 mm, but can withstand voltage more than 100 kV.
