Abstract

1GW iodine photodissociation laser beam (λ= 1.315pm) is focused to generate continuum X-ray radiation at a titanium (Z=22) target. A piece of aluminum (360Å) on mylar (8μm) film is used to isolate the soft X-ray emitted. Convex - curved mica (2d002 = 19.84Å) crystal spectrometer is used to obtain soft X-ray spectra and the slope of continuum X-ray spectra ( λ < 20Å) are found to show two different effective electron temperatures, 0.11 KeV and 7.1 KeV and we conclude there are two electron groups in the iodine photodissociation laser produced titanium plasma.
