“…This allowed monochromator designs, including all focusing options, based on proven monochromators at secondgeneration sources, e.g. the National Synchrotron Light Source (Rosenbaum et al, 1988), which are operationally much easier to handle, rather than on the inclined crystal geometry design (Khounsary, 1992) with liquid-gallium cooling (Smither et al, 1989) developed earlier at the APS.…”

The 19ID undulator beamline of the Structure Biology Center has been designed and built to take full advantage of the high flux, brilliance and quality of X-ray beams delivered by the Advanced Photon Source. The beamline optics are capable of delivering monochromatic X-rays with photon energies from 3.5 to 20 keV (3.5-0.6 A wavelength) with fluxes up to 8-18 x 10(12) photons s(-1) (depending on photon energy) onto cryogenically cooled crystal samples. The size of the beam (full width at half-maximum) at the sample position can be varied from 2.2 mm x 1.0 mm (horizontal x vertical, unfocused) to 0.083 mm x 0.020 mm in its fully focused configuration. Specimen-to-detector distances of between 100 mm and 1500 mm can be used. The high flexibility, inherent in the design of the optics, coupled with a kappa-geometry goniometer and beamline control software allows optimal strategies to be adopted in protein crystallographic experiments, thus maximizing the chances of their success. A large-area mosaic 3 x 3 CCD detector allows high-quality diffraction data to be measured rapidly to the crystal diffraction limits. The beamline layout and the X-ray optical and endstation components are described in detail, and the results of representative crystallographic experiments are presented.

“…Although many different kinds of double-crystal monochromators [1][2][3][4][5][6][7][8][9][10][11][12][13][14] have been developed and some of them are commercially available, they are extremely expensive and have some application limitations. Meanwhile, many investigators of the small Participate Research Team ͑PRT͒ desire to propose an x-ray beamline to be installed at the Synchrotron Radiation Research Center ͑SRRC͒.…”

A low-cost and flexible double-crystal monochromator for an x-ray beamline

This work designs and implements an inexpensive and simple double-crystal monochromator, which yields a high performance at a bending magnet x-ray beamline. A primary feature of the proposed monochromator is that the offset between the incident and monochromatic exit of the x-ray beam can be adjusted to cover a wide energy range with a short X -Y traveling stroke. Such a short range of X -Y strokes can reduce the monochromator's overall size and, also, increase the stability of motions. Meanwhile, in this monochromator, instead of using a complicated hardware linkage mechanism, a software program is developed to effectively control the X -Y stage for positioning the second crystal in a fixed exit configuration, alleviating mechanic motion errors to maintain the parallelism of the two crystals. The entire software control mechanical linkage offers a relatively inexpensive and simple assembly monochromator that is more flexible than the commercially available one.
