An investigation was made of the x-ray emission spectrum of a magnesium plasma heated by ruby laser pulses of 10--20 psec duration and 10/sup 14/ W/cm/sup 2/ power density on the target surface. The relative intensities of the spectral lines were used to determine the electron temperature (200 eV), density ((1--1.15) x 10/sup 20/ cm/sup -3/), and ionization state ((Li)/(He)approx. =1) of the luminous part of the plasma. The relative intensities of the resonance lines of the H- and He-like ions yielded an estimate of the electron temperature in the vicinity of the critical point (T/sub cr/> or approx. =550--700 keV).
