High Voltage Subnanosecond Monocycle Active Former Based on Compression Energy Unit

Compact high voltage subnanosecond monocycle former (MF) was tested. The device was designed on base of energy compression device and operated in a travelling wave mode. MF consists of high impedance and forming lines, which discharged for the load in parallel. As a result, the monocycle with pulse duration ∼1 ns and typical peak-to-peak amplitude ∼250 kV was formed without additional peaking of the nanosecond pulse rise time. Some pulses reached the maximum amplitude ∼270 kV. The parallel discharge circuit, and a spiral shape of forming line allowed keeping small dimensions of MF, and save enough electrical strength to operate with pulse repetition rate up to 100 pps.
