Synchrotron radiation circular-dichroism spectroscopy as a tool for investigating protein structures

Wallace, B.A

2000 Journal of Synchrotron Radiation

doi:10.1107/S0909049500009262 pmid:16609210

This paper reviews the use of synchrotron radiation circular dichroism (SRCD) spectroscopy for examining protein structures, discussing the differences between conventional circular dichroism and SRCD, as well as examples of what SRCD studies have revealed about protein structures to date. It...

Breast cancer diagnosis using scattered X‐rays

Lewis, R. A.; Rogers, K. D.; Hall, C. J.; Towns‐Andrews, E.; Slawson, S.; Evans, A.; Pinder, S. E.; Ellis, I. O.; Boggis, C. R. M.; Hufton, A. P.; Dance, D. R.

2000 Journal of Synchrotron Radiation

doi:10.1107/S0909049500009973 pmid:16609219

Small‐angle X‐ray diffraction data has been collected from 99 `core‐cut' breast tissue specimens representing a number of different pathologies. Data in the range 75–1390 Å have been compared with controls from patients with no breast disease. Bessel functions and Bragg maxima resulting from the...

Characterization of implanted semiconductors by means of white-beam and plane-wave synchrotron topography

Wieteska, K; Wierzchowski, W; Graeff, W; Turos, A; Grotzschel, R

2000 Journal of Synchrotron Radiation

doi:10.1107/S0909049500009420 pmid:16609215

AlxGa1-xAs epitaxic layers, with x = 0.43 and GaAs single crystals implanted with various doses of high-energy Se and Si ions, and silicon single crystals implanted with high-energy light ions were studied by means of different X-ray diffraction methods employing either a strongly limited white...

The effect of beam time structure on counting detectors in SRS experiments

Bateman, J.E

2000 Journal of Synchrotron Radiation

doi:10.1107/S0909049500007597 pmid:16609213

Counting detector systems are increasingly used in X-ray experiments because of their attractive properties as regards linearity, large dynamic range and simple noise properties. In synchrotron radiation source (SRS) applications of X-ray detectors, counting rates are generally high enough to...

Synchrotron beam test with a photon‐counting pixel detector

Brönnimann, Ch.; Florin, S.; Lindner, M.; Schmitt, B.; Schulze‐Briese, C.

2000 Journal of Synchrotron Radiation

doi:10.1107/S0909049500008682 pmid:16609212

Synchrotron beam measurements were performed with a single‐photon‐counting pixel detector to investigate the influence of threshold settings on charge sharing. Improvement of image homogeneity by adjusting the threshold of each pixel individually was demonstrated. With a flat‐field correction,...

Wavelength-dispersive double flat-crystal analyzer for inelastic X-ray scattering

Bortel, G; Alp, E.E; Sturhahn, W; Toellner, T.S

2000 Journal of Synchrotron Radiation

doi:10.1107/S090904950000950X pmid:16609217

A double flat-crystal analyzer for inelastic X-ray scattering is described. The general correlation between the energy and direction of the X-rays transmitted by the analyzer allows one to collect data for a range of energy transfers simultaneously. Such an analyzer with 120 meV resolution was...

Primary radiation damage of protein crystals by an intense synchrotron X-ray beam

Teng, T; Moffat, K

2000 Journal of Synchrotron Radiation

doi:10.1107/S0909049500008694 pmid:16609214

X-ray radiation damage of a lysozyme single crystal by an intense monochromatic beam from a third-generation radiation source at the Advanced Photon Source has been studied. The results show that primary radiation damage is linearly dependent on the X-ray dose even when the crystal is at...

First results from the Canadian SGM beamline at SRC

Yates, B. W.; Hu, Y. F.; Tan, K. H.; Retzlaff, G.; Cavell, R. G.; Sham, T. K.; Bancroft, G. M.

2000 Journal of Synchrotron Radiation

doi:10.1107/S0909049500007214 pmid:16609211

The first experimental results obtained from the Canadian SGM beamline at SRC (Synchrotron Radiation Centre, University of Wisconsin‐Madison, USA) are reported. The beamline is based on the Dragon‐type design, with a constant deviation angle, using photons from a second‐generation bending‐magnet...
