“…The scheme of the device was proposed in 1977 and used for the first time in experiments with laser-produced plasma [104,105,111,113,116,123,125,131]. The major contribution to the practical implementation of the spectrograph was made by A.B.…”

“…The operating principle of spectrographs with spherically bent crystals was described in detail in [104,124,125,147]. The main idea of the device is based on using the property of a spherical crystal mirror to focus X-ray emission.…”

“…Therefore, from the standpoint of X-pinch diagnostics, the main attention should be paid to creating diagnostic methods for detection and analysis of UV and X-ray emission of the Х-pinch plasma. The experience gained in laser plasma studies [100][101][102][103][104][105][106][107][108][109][110][111][112][113][114][115] is widely used when developing X-ray diagnostics. However, many new methods for X-ray spectroscopy of hot plasma were implemented for the first time namely in Х-pinch experiments .…”

Results of experimental studies of the Х-pinch since its invention and implementation in 1982 at the Lebedev Physical Institute are presented. The concept of the Х-pinch arose in the course of innovative experiments on studying the generation of hot dense plasma in nanosecond Z-pinches. The main idea was to localize the region occupied by the plasma and stabilize the moment of its formation. This was achieved by using a load in the form of crossed wires. The resulting plasma object turned out to be so interesting that a new scientific direction appeared in plasma physics. At present, studies in this direction are being performed in many laboratories worldwide. The term Х-pinch became conventional, and sections devoted to its study are always present at plasma conferences. Х-pinch is not only a very interesting scientific object, but also a unique source of X-ray emission with extreme parameters. The use of Х-pinches for point-projection X-ray radiography of high-energy-density objects provided many new experimental results. In some cases, the concepts of the processes occurring in matter upon fast energy deposition changed dramatically. The review consists of two parts. The first part briefly outlines the history of creation and studies of Х-pinches, describes the diagnostic techniques and devices developed during these studies, and presents the main results obtained in studying the physical processes occurring in the Х-pinch. The second part is devoted to the results of detailed studies of the Х-pinch hot spot-the region where the highest plasma parameters are achieved and which is a source of X-ray emission with extreme parameters. Some results of Х-pinch simulations are also presented.

“…Here we present 3 of 7 diagrams showing the changes in energy structure of relevant configurations against the atomic number Z (Figs. [13][14][15]. The energies were scaled in such a way, that the total width remains nearly constant, and the graphs were plotted so that the numerical data can be restored from them.…”
