Backscattering X-ray standing waves in the XUV region

T. M. Grehk, W. Drube, L. Kipp and G. Materlik

Synopsis: X-ray standing waves are generated in (001) backscattering geometry for a TiSe₂ single crystal at h 1033 eV. The modulation of the photoelectron yield was measured as a function of the photon energy. The data reveal disorder along the c-axis.

Synchrotron radiation circular dichroism spectroscopy: vacuum ultraviolet irradiation does not damage protein integrity

A. J. W. Orry, R. W. Janes, R. Sarra, M. R. Hanlon and B. A. Wallace

Synopsis: To test for the extent of radiation damage occurring during synchrotron radiation circular dichroism (SRCD) spectroscopic measurements at vacuum ultraviolet wavelengths, the chemical integrity and secondary structure of the protein myoglobin were examined by gel electrophoresis, mass spectrometry and SRCD spectroscopy. No changes were detected by any of these methods even after extensive irradiation, indicating that damage does not occur during SRCD measurements.

Preliminary experiment of fluorescent X-ray computed tomography to detect dual agents for biological study

Q. Yu, T. Takeda, T. Yuasa, Y. Hasegawa, J. Wu, Thet-Thet-Lwin, K. Hyodo, F. A. Dilmanian, Y. Itai and T. Akatsuka

Synopsis: The simultaneous detection of contrast agents by fluorescent X-ray computed tomography (FXCT) with synchrotron radiation is examined. FXCT could image the distribution of both iodine and xenon agents in a phantom clearly and the contrast ratio was significantly better than that of transmission X-ray computed tomography images.

A new ray-tracing program RIGTRACE for X-ray optical systems

T. Yamada, N. Kawahara, M. Doi, T. Shoji, N. Tsuruoka and H. Iwasaki

Synopsis: A new ray-tracing program has been developed. It traces consecutively each ray, following its path, and treats diffraction by a monochromator crystal by adopting the Darwin-Prins theory.

A new implementation of the molecular replacement method using a six-dimensional Patterson vector search

F. Jiang and Z. Rao

Synopsis: A six-dimensional exhaustive search algorithm has been developed to search unknown target structures in the Patterson vector space. The determination of both the rotation and translation parameters simultaneously is shown to have several advantages.
