Use Of X-Uv Multilayered Optics For Synchrotron Radiation, Plasma Diagnostics And Astrophysical Research.

X-UV multilayer mirrors have now been made and tested for about ten years , so it is the time to look if the initial hopes have been satisfied. These new mirrors have found applications in X-UV optical systems as Bragg reflectors alone, or combined with the grazing incidence mirrors and gratings. In this review paper we shall consider mainly the astrophysics, plasma physics and synchrotron radiation applications, the three fields for which the X-UV is an important range, to illustrate some kinds of problems which have been solved by using X-UV multilayered mirrors. Finally we shall try to indicate new promising directions.
