Line emission spectra of multiply charged ions excited in a laser plasma are obtained. The spectral resolution and spatial resolution of the device are limited by the cell size (13 \u03bcm) of the detector and amounted to \u223c103 and 26 \u03bcm, respectively. The stigmatism of the device makes it possible to use it for spectral diagnostics of plasma with a high spatial resolution. The device dimensions are about 1 m.<\/p>\n<p><strong>Keywords:<\/strong> imaging spectrograph, ultrasoft X-ray range, VLS grating, Mo\/Be multilayer mirror, Mo\/Si multilayer mirror, laser plasma.<\/p>\n<p><strong>Received:<\/strong> 04.07.2022<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A.
