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 (H α , 0.7171 nm and H β , 0.6052 nm) and helium-like (He α , 0.7757 nm and H β , 0.6634 nm) resonance lines are designed and the signal ratios of the H α line to the He α 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.
