Optical schemes for measuring (a) rocking curves and (b) angular profile and spectral density of X-rays from the high-heat-load monochromator. S1 and S2 – two pairs of slits; Si1 and Si2 – Si nnn crystals of the high-heat-load monochromator; Si3 and Si4 – Si 975 crystals of the high-energy-resolution monochromator; IC – ionization chamber; A – absorbers; APD – avalanche photodiode detector; CRL – beryllium compound refractive lens (optional). |
