“…Его рабочим телом является фольга или проволочки, расположенные в диэлектрической (дугогасящей) среде. ЭВРТ нашли применение при создании мощных источников энергии на основе взрывомагнитных генераторов для запитки лайнерных пондеромоторных узлов [2], а также для формирования высоковольтных импульсов в высокоимпедансных нагрузках [3,4]. В определенных условиях за счет быстрого роста сопротивления и низкой индуктивности ЭВРТ могут использоваться в качестве второго каскада обострения и формировать мегаамперные импульсы тока с фронтом ∼ 0.1 µs [5].…”

The results of studies of a solid-state closing switch for a high-current pulse switching are presented. The experiments were carried out on a laboratory facility with a capacitive energy storage run down a discharge circuit with electrical-explosive opening switch (EEOS) by a current pulse with an amplitude ~450 kA. The discharge circuit consists of two sections separated by a branch with a solid-state closing switch. A metal foil of the EEOS can be located in an interelectrode gap of the closing switch. The operation of the EEOS leads to a breakdown of the insulation of the closing switch, as a result of which an effective shunting of the section of the discharge circuit containing the EEOS occurs. The developed combined solid-state closing switch in the future is capable of providing multi-channel switching of a high-current pulse to the load synchronously with the EEOS operation.

“…The N-module 0.4-ineterdiameter DEMG with typical initial current Io = 6 MA at N = 10-15 [4,5] and N = 25 is used. The magnetic flux compression in the DEMG cavi-ties begins at current b (t=O), when the helical EMG is disconnected from DEMG, and is completed, when the shock waves from the disk charges enter DEMG TL (t. t 23 ps).…”

AbstracfTo study dynamic strength of materials according to the initial liner perturbation'growth in Rayleigh-Taylor insta-bility development, three-layer liner systems driven by azimuthal magnetic field pressure have been suggested. This paper demodtrates that 0.4-m-diameter disk EMG ensuring currents up to -70 MA can be used for this pur-pose. In the three-layer liner systems, the liner shock-free loading to more than 1 Mbar pressures is therewith possi-ble, with the pressures rising for times longer than 1 ps or longer than 0.3 ps in different systems. Here the shock loading of the liners under study is possible up to 3 -4 Mbar pressures.Examples of 2D computations of the initial perturbation growth in the liners under study at shockfree and shock pressures up to 1 Mbar, strain rates up to 10' sec-', and strains up to 200 % are given.

This current is initial one for the subsequent process of current amplification with the help of explosive. The high-speed implosion of a condensed liner is anThe explosive compresses an inductive circuit fast (in efficient method to achieve the state of substance time, which smaller than time of a magnetic flow characterized by high energy density, temperature and attenuation in an generator inductive circuit), pressure.continuously superseding a magnetic flow to load. TheThe experimental procedure for radiographing the compression of an inductive circuit should be carried out perturbations growing in the cylindrical aluminum liner continuously without occurrence of cavities, that a having the walls 2 mm thick, which is imploded under the magnetic flow will superseded in loading with the effect of 35 MA pulses produced by high-power explosive minimal losses. Then a current I = / L and magnetic magnetic disk generator (DEMG), is described. energy W = 2/ 2L grow with reduction of circuit System shielding the X-ray film situated at a distance of inductance L according to a degree of preservation of a 40 sm from HE explosive of 100 kg in the explosive magnetic flow. magnetic generator is described in detail. Specially arranged units having low total thickness equivalent to shield the film 15 mm of aluminum were used to provide the necessary protection from damage but still allowed the needed picture contrast.The developed procedure demonstrates the efficiency of EMG in the experiments on pulsed hydrodynamics and high-speed implosion of liners.
