Time resolved x-ray emission from nanosecond vacuum discharge with virtual cathode

Design features and parameters of a modernized installation of inertial electrostatic confinement based on a low-energy nanosecond vacuum discharge (similar to 1 J) are described when operating in diode geometry in the virtual cathode formation mode and the corresponding potential well. The device is used to study the processes of collisional DD synthesis in the interelectrode space, the processes of x-ray generation in complex plasma at various stages of the discharge: from the very initial stage, when the beam of autoelectrons only begins to irradiate the nonideal anode surface, to oscillating plasma configurations in later stages of the discharge. Here, the first steps were done to introduce x-ray spectral diagnostics, as well as to obtain the integral x-ray spectra for visualizations of interelectrode complex plasmas.
