Abstract
We report theoretical and experimental investigations of the x-ray properties of concave cylindrical mirrors for the soft x-ray (SX) band. Elements of this type facilitate solutions of many problems in the control of synchtrotron-radiation (SR) beams. These include: operation of SR channels; production of a vertical SR beam; transmission of an SR beam to another horizontal plane (to the second story); effective filtering-out of short-wave radiations. We describe the main features of deflection of SX beams by concave surfaces. The angular and spatial distributions of the radiation intensity at the exit from a cylindrical mirror are analyzed by the tridiagonal method. Experimental results are presented on the rotation of an SR beam through 90° by a cylindrical mirror with a reflecting carbon coating. The efficiency of the SR transfer was investigated in wide range\(\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{\lambda } \)∼10–100Å, and furthermore the angular and spectral distributions at the exit of the rotary mirror were measured. The influence of a thin carbon film covering the refecting surface on the x-ray and optical parameters of the cylindrical lens are discussed in the conclusion.
