Abstract
The monochromator of the Kosmos synchrotron radiation metrology station is described. The results of testing the monochromator in the energy range of 2000-6000 eV using Si (111) crystals are given. A spectral resolution at the level ΔE/E= 10-4 is obtained. A technique for checking verification spectral purity of the monochromatic radiation is described. It is shown that the monochromator can be used for spectroscopic measurements in the specified subrange.
