Laser plasma X-ray emission studies using an imaging transmission grating spectrometer. I. Principles and methods

成功地研制了一台用于激光等离子体软X射线(0.5～20nm)辐射特性研究的针孔透射光栅谱仪(PTGS)。文中对PTGS的成像及衍射原理进行了分析,并给出了实验上确定光栅常数和计算真实发射谱的方法。

A PTGS (Pinhole Transmission Grating Spectrometer) has been developed successfully for laser plasma soft X-ray emission (0.5-20nm) studies. Fundamental principles of imaging and dispersion of the key element PTG (Pinhole Transmission Grating) are presented in detail. Methods of determining the grating parameters and calculation of the real spectra are given.
