A linear transformer is an annular parallel connection of switches and capacitors designed to deliver rapid high power pulses. The linear transformer was designed at the Institute of High Current Electronics (IHCE) in Tomsk, Russia. The GSP is capable of producing high current, up to 1 megaamp pulses with a risetime of less than 100 ns. This is an improvement over Marx generator based pulsed power devices which require pulse compression to achieve such fast risetimes. It is being considered as a driver for z-pinchbased inertial confinement fusion.
