摘要
The use of an X-ray waveguide for scattering experiments at an undulator of a third-generation synchrotron radiation source is discussed. The performance with a perfect crystal monochromator, multilayer monochromator and focusing mirror is explored. A maximum flux of 8 x 10(9) photons s(-1) at lambda = 0.083 nm was obtained for a 0.15 (V) x 600 (H) mu m(2) beam at the exit of the waveguide with a multilayer monochromator. The combination of an Si(111) monochromator and ellipsoidal mirror resulted in a flux of similar to 10(9) photons s(-1) but with a horizontal compression of the beam to similar to 30 mu m. The use of the waveguide in diffraction experiments is addressed.
