Determination of laser plasma temperature from study of radiation in roentgen and visible regions of spectrum

A laser plasma temperature of T_e 20 eV is determined by the foil method from measurements in the region of soft roentgen radiation. Measurements of radiation intensity in the visible region of the continuous spectrum give values of the temperature of T 15 eV for the part of the plasma which is opaque in the visible region of the spectrum.Translated from Zhurnal Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 1, pp. 114–117, January–February, 1972.The authors are grateful to V. E. Panchenko and M. Yu. Lel'chuk for aid in conducting the roentgen measurements, as well as to A. M. Orishich and A. I. Shusharo for participating in the experiments on optical diagnostics.
