(a) Divergence of the beam at the MRH goniometer measured by the FWHM of the rocking curve of the Si(400) single-crystal reflection as a function of the bending of mirror M2 (bending radius of mirror M1 = 20.93 km, wavelength λ = 0.10008 nm). The sample was Si〈100〉 implanted with 5 × 1015 C+ (195 keV) cm−2 at 773 K (non-ideal crystal). (b) Intensity variation of the incident beam at the MRH goniometer position as a function of the bending of mirror M2 under the same conditions. |
