A stigmatic plane grating monochromator (PGM) and a 4-meter normal incidence monochromator (NIM) were recently installed on undulator sources at the Synchrotron Radiation Center (SRC). Details of their design, installation, and performance will be reported. A new pure permanent magnet (PPM) undulator will be installed next year. The design criteria for spectroscopy beamlines utilizing this source as well as two possible monochromator designs, a modified Wadsworth and a varied line spacing (VLS) monochromator, will be discussed. © 2000 American Institute of Physics.

    The locations of self-reproduction planes in the Talbot effect and the distance between coherence peaks in the Lau effect are functions of the radiation wavelength. This fact can be used to develop new methods for spectral investigations. Below, we estimate the spectral selectivity of Talbot and...
