在激光等离子体研究中,电磁脉冲干扰对实验结果影响很大,为了减小这一影响,设计一款新的扫描晶体谱仪,整个机身设计成几乎全密闭的良导体。该晶体谱仪通过更换晶体和调整入射角可以获得较宽范围的测量窗口。在X光光谱为2.5~3.5keV范围内的测量试验中,该扫描晶体谱仪的谱分辨能力为13(在2960eV),时间分辨率为10ps。其谱分辨和时间分辨可以满足对激光等离子体的研究。 In the study of laser plasma, electromagnetic pulse interference has a great influence on the experimental results. In order to reduce this influence, a new scanning crystal spectrometer is designed, and the entire fuselage is designed as an almost fully sealed good conductor. The crystal spectrometer by changing the crystal and adjust the angle of incidence can be a wide range of measurement window. In the X-ray spectrum of 2.5 ~ 3.5keV range of measurement experiments, the spectral resolution of the crystal scanning spectrometer 13 (at 2960eV), the temporal resolution of 10ps. Its spectral resolution and time resolution can satisfy the research of laser plasma.
