摘要：

Characterization of the X-19 beamline at the National Synchrotron Light Source (NSLS) is described. The beamline is designed for high-resolution X-ray absorption spectroscopy over a wide energy range. All of the beamline optical components are compatible with ultrahigh vacuum (UHV) operation. This permits measurements to be made in a windowless mode, thereby facilitating lower energy (< 3 keV) studies. To upgrade the beamline performance, several possible improvements in instrumentation and practice are discussed to increase photon statistics with an optimum energy resolution while decreasing the harmonic contamination and noise level. A special effort has been made to improve the stability and UHV compatibility of the monochromator system. Initial X-ray absorption results demonstrate the capabilities of this beamline for X-ray absorption studies of low-Z elements (e.g., S) in highly dilute systems. The future use of this beamline for carrying out various X-ray absorption experiments is presented. © 1990.
