High-power megavolt pulse generator with nanosecond rise time
- Russian Academy of Sciences, Tomsk (Russian Federation); and others
A pulse generator with a power of 0.1 TW, an amplitude of up to 2 MV and {approximately}1.5-nsec rise time is described. A Marx voltage pulse generator charges a low-inductance capacitor (1.8 nF) and a radial line (0.9 nF) to a voltage of {approximately}2 MV in 200 nsec. At the peak voltage, a water switch is actuated at the center of the radial line resulting in {approximately} 2.5-MV voltage pulse at the end of the line. This pulse propagates along the oil-insulated line. The line is connected to an oil-filled peaking switch with a metal diaphragm, which reduces the transfer capacitance of the discharge gap to 5 pF to match the radial-line wave impedance to the load connected to the switch output. A crossover switch may be used when operating in the short-pulse mode. A pulse with a width of up to 20 nsec has been generated across a load equivalent matched to the line.
