摘要: Two curved crystal spectrometers are setup on "QiangGuang-1" generator to measure the z-pinch plasma spectra emitted from planar aluminum wire array loads. The Kodak Biomax-MS film and IRD AXUVHS5# array are employed to record time-integrated and time-resolved free-bound radiation respectively. The photon energy recorded by each detector is ascertained by using the L-shell lines of molybdenum plasma. Based on the exponential relation between the continuum power and photon energies, the aluminum plasma electron temperatures are measured. For the time-integrated diagnosis, several "bright spots" indicate electron temperatures between (450 eV~520 eV)± 35%. And for the time-resolved ones, the result shows that the electron temperature reaches about 800 eV±30% at peak power. The system satisfies the demand of z-pinch plasma electron temperature diagnosis on ~1 MA facility.
