On the use of clessidra prism arrays in long-focal-length X-ray focusing

W. Jark, M. Matteucci and R. H. Menk

Synopsis: X-ray kinoform lenses of the clessidra type, which are composed of many small triangular prisms, can be used under suitable conditions effectively as arrays of refractive micro-lenses. These arrays can provide relatively large apertures in long-focal-length focusing.

Light flux density threshold at which protein denaturation is induced by synchrotron radiation circular dichroism beamlines

A. J. Miles, R. W. Janes, A. Brown, D. T. Clarke, J. C. Sutherland, Y. Tao, B. A. Wallace and S. V. Hoffmann

Synopsis: Radiation damage by heating of samples at high-flux synchrotron radiation circular dichroism spectroscopy beamlines can result in protein denaturation. This study compares the degree of damage that occurs at a number of beamlines worldwide in order to define the threshold beam flux density above which significant denaturation occurs.

Comparison of calculated brightness and flux of radiation from a long-period wiggler and a short-period undulator

T. Shaftan, S. L. Hulbert and L. Berman

Synopsis: The radiation properties of two classes of insertion devices, a long-period wiggler and a short-period undulator, are calculated and compared, using different computer codes. Special care is found to be needed when modeling these properties.

S. Cornaby and D. H. Bilderback

Synopsis: X-ray transmission mirrors, which function as high-pass energy filters, have been made out of silicon nitride and tested in synchrotron X-ray beams. The high-energy cut-off can be selected by adjusting the incidence angle of the transmission mirror.

Spatial resolution limits for synchrotron-based spectromicroscopy in the mid- and near-infrared

E. Levenson, P. Lerch and M. C. Martin

Synopsis: Spatial resolution measurements at Advanced Light Source beamline 1.4.4 are used to determine the wavelengths at which a cross-over from diffraction-limited to electron-beam-source-size-limited resolution occurs. Performance is then predicted for different synchrotrons, beamline optics and endstation microscopes.
