| Abstract: | Transmission grating spectrometer is applied in the area of inertial confinement fusion and other laser plasma interaction experiments. Accurate spectrum estimation depends on the measurement uncertainty. Based on the transmission grating diffraction efficiency calibration experiments, the uncertainty of diffraction efficiency is analyzed. Then the uncertainty of X-ray spectrum unfolding progress is investigated. The total uncertainty of the measured spectrum is obtained for 0.1 to 5 keV.
