Analysis of Continuum X-ray Specturum and Determination of Electron Temperature from Iodine Photodissociation Laser produced plasma

1-GW Iodine photodissociation Laser (λ=1.315${\mu}{\textrm}{m}$)is focused to generate the continuum x-ray radiation at titanium(z=22)target. A piced of aluminum(360 )-mylar(8${\mu}{\textrm}{m}$) film is used to isolate the soft X-ray radiation emitted. Convex-xurved mica crystal spectrometer is used to obtain the soft x-ray spectra from the laser titanium target plasma and the slope of continum X-ray spectra are found to show two different different electron effective temperaturres, 0.11keV and 7.1KeV. We compare the two temperature result with the foil absorption method.
