“…This appeared to restrain researchers' efforts to increase the energy parameters of non-chain HF (DF) lasers. Although there have been numerous works concerned with non-chain HF (DF) lasers, the radiation energy attained for them by 1996 was at the level of 10 J [16][17][18]. The incompleteness of the traditional understanding of the physics of forming SSVD in dense gases came to be understood after we found that it was possible to obtain discharge in SF 6 and mixtures of SF 6 with hydrocarbons (deuteron-carbons) in the systems of plane electrodes with high electric field enhancement at the edge without any preionization in a gas [2,3].…”

“…It should also be mentioned that analysis of the literature data indicates a negligible role for preionization in the formation of SSVD in non-chain lasers. For example, in [16], where a set of metal rods connected to a common busbar through a resistance (resistance uncoupling) served as the discharge gap cathode, preionization was absent, while in [18] it was performed through a high current dielectric surface discharge whose spectrum displayed not only UV radiation, but also soft x-ray radiation.…”

Dedicated to the 100th anniversary of the birth of Academician A M Prokhorov, this paper reviews the physics of self-sustained volume discharge without preionization-self-initiated volume discharge (SIVD)-in the working mixtures of non-chain hydrofluoride HF (deuterofluoride (DF)) lasers. The dynamics of SIVD in discharge gaps with different geometries is thoroughly described. The mechanisms for the restriction of current density in a diffuse channel in electric discharges in SF6 and SF6 based mixtures (which determines whether SIVD is possible) are proposed and analyzed using simple models. The most probable mechanisms are the electron impact dissociation of SF 6 and other mixture components, electron-ion recombination and electron attachment to vibrationally excited SF 6 molecules. Starting from a comparative analysis of the rate coefficients of these processes, it is shown that electron-ion recombination is capable of compensating for electron detachment from negative ions via electron impact. It is also established that SIVD is not only observed in SF 6 , but also in other strongly electronegative gases. The factors that determine the uniformity of the active medium in non-chain HF (DF) lasers are analyzed. Some special features of non-chain HF (DF) lasers with different apertures operating are carefully examined. Consideration is given to the problem of increasing the aperture and discharge volume of non-chain HF (DF) lasers. Based on our experimental results, the possibility of increasing the energy of such lasers to ~1 kJ and above is shown.

Pulse sources of electromagnetic radiation based on a low-inductive extended z-discharge are studded experimentally and numerically. Z-discharge is initiated by a high-voltage pulse generator through a long transmission line. It is shown that using a sliding avalanche discharge traveling wave, one can provide electrical breakdown of long discharge gaps in a wide range of initial gas pressure and produce a plasma column at moderate voltages of the generator. Sources alloy to obtain the electromagnetic radiation of different kinds, from red visible range up to hard x-ray one. A new nonpinch mechanisms of radiation generation are discovered in the soft and hard x-ray ranges of spectra. These mechanisms offer a higher efficiency of conversion of elecnrical energy to the energy of a radiating medium.
