EFFECT OF AN ELECTRON-BEAM GENERATED IN AN X-PINCH PLASMA ON THE STRUCTURE OF THE K-SPECTRA OF MULTIPLY-CHARGED IONS

The first experimental studies of an electron beam generated in an X p inch on the XP machine (Cornell University, USA) and the BIN machine ( P. N. Lebedev Physical Institute, Russian Academy of Sciences) are rep orted. It is shown that it is possible in an X pinch to isolate the ef fect of a plasma-generated electron beam on the multiply charged ion r adiation. The intensities of the satellite lines corresponding to Li-, Be-, B-, and C-like ions are calculated for the Al spectrum on the ba sis of a collisional-radiative model with a non-Maxwellian electron di stribution in the plasma. The effect of an electron beam on the multip ly charged light ion radiation in an X-pinch plasma is demonstrated. C omparing our calculations with the experimental spectra, we conclude t hat the present model can be used to estimate the electron beam intens ity. (C) 1997 American Institute of Physics.
