The results of a miniature plasma focus are presented in this paper which is operated with energy less than or equal to 150 J. The miniature plasma focus is driven by a small capacitor bank and the peak current delivered in the focus is 75–80 kA. The deuterium gas is filled with a pressure range of 5–7 mbar inside the plasma focus chamber. The quartz glass is used for generating initial surface breakdown...
The design, construction and operational characteristics of a portable flash X-ray source driven by battery-powered compact Marx is reported. The novel configuration of compact Marx utilizes hollow capacitors in successive stages to enhance the erection reliability. The characteristic impedance of this system is ∼200Ω. At discharge of ∼22kV, >200kV output pulse of 60ns duration (FWHM) with rise...
The results of a miniature plasma focus are being presented in this paper which is operated with energy less than or equal to 150Joules. The miniature plasma focus is driven by a small capacitor bank and the peak current delivered in the focus is 75kA. The deuterium gas is filled with a pressure range of 5–7mbar inside the plasma focus chamber. The quartz glass is used for generating initial surface...
The results of a pulse power generator driving an axial virtual cathode oscillator are being presented in this paper as a source of high power microwave (HPM) radiations. The electron beam generator is also modified to attain the intense X-ray burst. The pulse power generator used for these applications is common and is having 10 ohms as its characteristic impedance with 50nS of pulse width. The peak...
Railgap switches are connected to transfer energy from high energy capacitor bank to enable large coulomb transfer in distributed monde in 1.2MJ capacitor bank ‘RUDRA’ at Energetics & Electromagnetics Division, BARC, Visakhapatnam. The total energy stored in the 1.2MJ bank is segmented in to six modules (of 200kJ each) capable of delivering 3.6MA of peak current with 5 to 7\is rise time collectively...
