Abstract
Summary form only given. A device that integrates a Johann-type spectrometer with the x-ray PIN diodes, positioned accurately on the rowland circle of the cylindrical bent crystal with different Bragg angles to aim at different spectral lines, has been developed for measuring th e time-resolved K-shell line emissions of the imploding Al wire array. Four typical channels respectively keyed to the Al ion hydrogen-like (Hα, 0.7171 nm and Hβ, 0.6052 nm) and helium-like (Heα, 0.7757 nm and Hβ, 0.6634 nm) resonance lines are designed and the signal ratios of the Hα line to the Heα line has been used to retrieve the time-dependent electron temperature. The designing principle of the spectrometer is described and the preliminary experimental results on the YANG and PTS accelerator are presented and analyzed.
