Dynamics of formation and evolution of the hydrogen liner in the inverse Z-pinch configuration, and nuclear reaction (pd &#x2192; <sup>3</sup>He+&#x03B3;(5.5 MeV) in the ultra low range of collision energies were studied at the pulsed power generator MIG. The upper limits for the astrophysical S-factor and effective cross section of the pd reaction in the(More)
The bremsstrahlung output obtained from the interaction of a relativistic electron beam with converter foil has been studied experimentally. The experiments were carried out on SNOP-1 accelerator at 0.4-1.1 MV, 320-120 kA and pulse with FWHM of 20-65 ns. The electron beam energy was about 10 kj and the power was 0.18 TW. For generation of the higher(More)
Summary form only given. Since 2006, researches of the X-pinch dynamics have been carried out at the Institute of High Current Electronics (Tomsk, Russia) on compact pulsed power generators (100-250 kA, 110-180 ns) of our own design. Considerable amount of the experimental data was accumulated during these years. It was shown experimentally that at the(More)
This paper presents experimental results on the shot pulse (&#38;#60; 20 ns) &#x03B3;-ray generation. The experiments were carried out on the MIG facility, which consists of 240 kJ high voltage linear pulse transformer (LPT), two water lines, vacuum inductive energy storage (IES), plasma opening switch (POS) and diode. The POS parameters have been(More)
A versatile X-ray source has been designed based on a unitary pulse power system. The source makes it possible to perform investigation and tests in a wide range of quantum energy. A line pulse transformer with a stored energy of 250 kJ is used as a base for powering the system [1]. The design of a multi-purpose pulse generator (MIG) is a quite reasonable(More)
Experimental models of capacitors meant for using in directly operated pulsed power systems with energy supply time to load of 500 ns have been designed. It is supposed that the capacitor with energy output of 20 kJ would be rather perspective used as an elementary unit in such systems. At present time, an intermediate model HCEIcap50-4 is being tested and(More)
The paper reports on recent developments in the field of design, manufacturing, and testing of compact capacitive energy stores with an energy transfer time of 100 ns, namely high-voltage pulse capacitors, capacitor-switch assemblies, and artificial forming lines, at the High Energy Density Department of the Institute of High Current Electronics.

In this work, experiments have been performed on the MIG generator with a water transforming line on exit (the impedance 0.65-0.34 &#x03A9;, the peak pulse power 1.5 TW) to explore the possibilities of producing multimegabar pressures by electrodynamic implosion of condensed cylinders. The generator produces a current of 3-3.5 MA with a risetime of ~70 ns(More)
A set of neutron diagnostics including scintillation time-of-flight detectors, bubble detectors, and several kinds of threshold nuclear activation samples is used to obtain information about the yield and spectrum of the neutrons produced by a deuterium gas-puff z-pinch. The experiments are performed at a current of about 3 MA on the GIT-12 generator at the(More)
