XRD ABSORBING FOIL METHOD FOR MEASUING PLASMA RADIATION TEMPERATURE

This paper describes a X-ray diode (XRD) absorbing foil method to measure radiation temperature of hohlraum irradiated by 1.05μm laser, and introduces especially principle of the method, the program computation, selective rule of filters and state of the measurement at LF-12 in 1989, hohlraum's X-ray escaping energy and radiation temperature time spectrum are estimated, experiment results are in agreement with that of filter XRD's array (Dante) in error range.
