ABSTRACT
Varied line spacing (VLS) monochromators are now a standard part of the repertoire of synchrotron radiation. Four are installed at the ALS, one each at BESSY II and LURE, and at least ten in Japan. Many VLS spectrometers have also been constructed. VLS monochromators offer significant advantages over other fixed deviation designs; fixed exit slit, simple scanning motion, built-in demagnification, high spectral resolution, compactness, and a zero order image in focus at the exit slit. These features lead to low cost and user-friendly operation. This paper reviews a particular VLS design and compares its performance with an equivalent SGM. © 2000 American Institute of Physics.
