Ia. Zhitnik et al., INVESTIGATION OF MULTILAYER X-RAY MIRRORS FOR LAMBDA-APPROXIMATE-TO-19 NM SPECTRAL RANGE WITH THE HELP OF LASER-PLASMA RADIATION SOURCE, Kvantovaa elektronika, 20(1), 1993, pp. 89-94
On the basis of a Q-switch Nd:YAlO3 laser (second harmonic lambda = 0.
54 mm) a laser-plasma radiation source has been created for the invest
igation of focusing X-ray multilayer mirrors of normal incidence. By t
he example of Mo-Si coating mirror (lambda=19.3 nm), the possibility t
o measure angular resolution of less than 1'', spectral dependence of
reflectivity and its uniformity across the aperture is shown.
