Abstract:
A stigmatic grazing-incidence flat-field grating spectrograph was developed. The spectrograph consisted of a variable line-spacing concave grating and a grazing-incidence collecting optics composed of a cylindrical mirror and a spherical mirror. Using this spectrograph, we have obtained soft x-ray spectra of line-focused laser plasmas with good spatial resolution along the normal of the target surface over the entire wavelength range covered by the spectrograph.
