“…In contrast to our previous experiments [14,15], the used diffraction grating (3, figure 1) had an extremely large slit length (2 cm), inside and along which there are free-standing gold bars. To visualize the spectra, a quadrant MCP radiation recorder was used (4, figure 1), the working field of which was separated into four sectors, which allowed one to obtain up to four time-separated consecutive frames of the source image (6, figure 1).…”

“…In the past a number of publications reported that loads made of flat or cylindrical foils, composed of different materials and different sizes, were exploded with pulse high-current generators for the purpose of various applications [1][2][3][4][5][6][7][8][9][10][11][12]. Under the 1000 Å), as well as soft x-ray (SXR) radiation (2 Å < λ < 100 Å) [13][14][15]. It is obvious that during the explosion of foils, we should also expect the presence of radiation of this range, which can be used to study the processes occurring in the foil load when a powerful current pulse passes through it.…”

“…The generation of short wavelengths ultraviolet radiation is directly connected with the creation of plasma sources with a sufficiently high temperature (T e 50-100 eV) and high energy conversion efficiency 'from the outlet'. The use of low-voltage generators (with a voltage below 50 kV) [14,15] with loads in the form of foils seems to be the most preferable for the purpose of creating a soft x-ray and extreme ultraviolet (SXR/EUV) radiation source among other pinch devices. In our experiments [14,15] there is practically no generation of hard x-ray radiation, which is undesirable for a number of applications (for example, lithography).…”

The results of studies of the soft x-ray and extreme ultraviolet (SXR/EUV) radiation of thin flat aluminum foils and wires under the explosion in an electric discharge on the compact high-current KING generator are presented. These studies were based on the SXR/EUV spectroscopy with a spectral resolution of 6 Å, a temporal resolution of 5 ns and a spatial resolution of 200 μm. To study the plasma radiation of exploded foils and wires in the SXR/EUV range, we used a transmission diffraction grating spectrograph which in combination with two additional slits provided spectral and spatial resolution. The spectrograph was coupled with a four-frame recorder based on a microchannel plate for providing temporal resolution. The analysis and comparison of the spectral, spatial, temporal, and energy characteristics of the SXR/EUV radiation of plasma formed under the explosion of foils and wires of a similar mass made of aluminum was carried out. The spectra were calculated as well and the plasma parameters and their changes in time and space were estimated on the basis of these calculations and comparison with relevant experimental results. Experiments have shown that when foils explode, a single intense source of SXR/EUV radiation is formed with radiated energy in the range of 10-20 J and a power of up to 100 MW in the quantum energy range from 30 to 250 eV. At the same time, the radiation power under the explosion of foils turned out to be about twice above the power under the explosion of wires of comparable mass.

Obtaining new data on the gas-dynamic responses from the polymer samples (polytetrafluoroethylene, PTFE) irradiated by powerful VUV radiation from compressed plasma flows is in the focus of the present study. An erosion type magnetoplasma compressor (MPC), a type of plasma focus discharge, was used as a radiation source. The operating voltages of the MPC were between 15 and 25 kV, the maximum measured discharge current was 200 kA, and the radiation energy in the VUV range was ≈1–2 kJ. The VUV fluxes on the sample surface were high and equal to ≈1022–1024 photons cm−2·s−1. Double-exposure laser holographic interferometry and schlieren photography were used to diagnose and visualize the gas-dynamic structures. The spatial distribution of the parameters (temperature, pressure and concentrations of electrons and ions) was defined based on the assumption of local thermodynamic equilibrium. It has been demonstrated that the maximum temperature ranged from ≈ 10 to 15 kK in the plasma layer. The electron concentration was ≈ (0.7–1.6) × 1018 cm−3 in this region. The used techniques of optical diagnostics and procedures of result processing make it possible to obtain data on the dynamics of polymer ablation, which occurs when their surface is exposed to powerful energy fluxes (thermal, shock-wave, radiation, and other extreme loads).
