| Abstract: | The thermal load caused by the absorption of synchrotron radiation in X-ray optical elements of the Belok and RSA stations
leads to optics elements heating and induces strains upon simultaneous cooling. The heating of the cooled first crystal in
the double-crystal monochromator causes its bending and increases the reflected beam divergence, which, in turn, results in
the monochromatic beam intensity loss 1]. Numerical simulation makes it possible to more accurately determine the strains,
choose the optimal monochromator design, estimate the vertical sizes of the focal spot and wavelength resolution in the focusing
channel, correctly design the system for cooling the mirror at the channel input, and choose a design providing the minimum
temperature of the beam-limiting slit knives. |
