A method bas been developed for measuring radiation temperatures using a set of absorption-foils coupled to a soft X-ray streak camera in laser plasme experiments. A result has been given for a planar gold target irrdiatcd by laser (λ = 1.053μm) pulses of about 360ps in duration with average intensities of about 1014W/cm2 from the LF-11# Nd: glass laser facility. In addition, applications to measuring time-resolved spectra and space-resolved temperature are discussed.
