The possibility of turning soft X-ray beams through large angles with the help of concave mirrors is shown. For a carbon-coated superpolished concave mirror a reflectivity of 60% is measured for 6.76 nm radiation and a turning angle ψ = 29°, which is two orders higher than for beam deflection by the same angle with one Fresnel reflection from a plane carbon mirror.
Concave glancing incidence mirrors for deflection and turning of soft X-ray beams by large angles are considered. For carbon-coated superpolished concave mirror the reflectivity of 60% is measured for 6.76 rim radiation and turning angle T = 29°, which is two orders higher than for beam deflection by the same angle with one Fresnel reflection from a plane carbon mirror.
