“…In the context of z pinches these regions are called "bright spots" (or sometimes hot spots) : their diameter is quoted as 50-100 pm (Stallings 1979;Burkhalter 1979;Riordan 1981). However, when a single group looks at both vacuum sparks and z pinches the bright spots in z pinches seem identical to plasma points (Alikhanov 1984;Gol'ts 1986;Gol'ts 1987). Perhaps these lower values reflect the spectral features used in the interpretation.…”

This review discusses the intense x-ray emitting regions, called plasma points, that appear in low-inductance vacuum sparks and other high-current discharges. Accurate x-ray spectroscopy indicates the existence of two types of plasma points with different plasma parameters. One type is extremely small ( -microns), dense ( -1023/cm3), and hot ( 2 1 keV), while the second type is an order of magnitude less extreme. A dynamic model (Vikhrev 1982a) based on radiation cooling with axial outflow of plasma predicts a radiative collapse that is consistent with many features of the plasma points. R21
