APPARATUS FOR OBTAINING IMAGES OF A PLASMA OBJECT IN SOFT X-RAY AND EXTREME ULTRAVIOLET SPECTRAL RANGES WITH SPECTRAL, SPATIAL AND TEMPORAL RESOLUTIONS SIMULTANEOUSLY Russian patent published in 2023 - IPC G01J3/18 

FIELD: imaging.

SUBSTANCE: invention relates to the field of plasma diagnostics and pertains to an apparatus for obtaining spectral images of a plasma object in soft X-ray and extreme ultraviolet spectral ranges. Apparatus comprises a slot mask, a diffraction grating, a microchannel detector, and an image recording device optically coupled with the microchannel detector. The slots of the slot mask are located at equal distances from each other and are perpendicular to the grooves of the transmission diffraction grating. A multistrip or four-sector microchannel detector is used as a microchannel detector. The number of slots is equal to the number of strips in the multistrip microchannel detector or two if a four-sector microchannel detector is used.

EFFECT: possibility of obtaining spectral images of a plasma object with spatial and temporal resolution simultaneously.
