Abstract

The characteristics of input energy control with an intense pulsed power device was investigated to explore the properties of warm dense matter in an implosion time scale of inertial confinement fusion. An electron beam diode, which served as an impedance controller and could suppress the prepulse, was placed on the output terminal of the intense pulsed power device. The anode (output) current was regulated by changing the gap distance of the electron beam diode. The input energy into the dummy load representing the sample was controlled with the electron beam diode.
