Theme: Disordered Structure Probed by High-energy X-ray Diffraction Technique
Shinji Kohara (JASRI/SPring-8)

High-brilliance and high-energy X-rays are one of the biggest advantages of SPring-8. The use of high-energy X-rays allows us to measure diffraction patterns up to high-reciprocal space in transmission geometry with small scattering angles and small correction terms, which provides more detailed and reliable structural information of disordered materials (glass, liquid, and amorphous materials) than has hitherto been available. In this course, we will focus on the structural analysis of disordered materials by the diffraction measurement. We will learn how we can obtain a reliable diffraction data for disordered materials and how we analyze the data. Furthermore we will try to perform structural modelling of disordered materials on the basis of diffraction data employing a computer simulation technique.

Theme: Probing Atomic Vibration using Nuclear Resonant Inelastic Scattering
Yoshitaka Yoda (JASRI/SPring-8)

Quantized vibrational motion is called a phonon, which is investigated by several spectroscopic methods such as Raman spectroscopy, inelastic X-ray scattering and neutron scattering. Its typical energy range is ~100 meV. Nuclear resonant scattering (NRS) is caused by a nuclear level, which has ~neV energy width. Every isotope has different nuclear level, so NRS has distinguished feature of just probing a specific isotope. Recently biochemical materials such as an enzyme have been intensively studied by NRS to focus on its active center in the complicated system. In the beamline practical, we will introduce a high-resolution monochromator and a fast timing detector, which have crucial roles to realize this spectroscopy at synchrotron radiation and a model sample will be measured in the cryostat.

Theme: Data Collection and S-SAD Phasing of Protein Crystals
Kazuya Hasegawa (JASRI/SPring-8)

Phase problem is a major difficulty in protein crystallography. Recently, S-SAD phasing method has been got attention because it does not need heavy atom derivative and is expected to improve the throughput of structure determination. On the other hand, it has a potential difficulty because of the small anomalous signal of sulfur atom. Therefore, the precise measurement of the anomalous signal is crucial. In this exercise, we plan to collect diffraction data from a protein crystal with various condition and examine what is important for the successful structure determination by S-SAD phasing.

Theme: Handling of X-ray Polarization and Application to X-ray Magnetic Circular Dichroism Spectroscopy
Motohiro Suzuki, Naomi Kawamura and Masaichiro Mizumaki (JASRI/SPring-8)

  X-ray magnetic circular dichroism (XMCD) is a useful tool to investigate magnetic properties because of an element specificity, electronic shell selectivity and angular-momentum sensitivity. In particular, unnecessary ultrahigh-vacuum in hard X-ray region is effective to measure the XMCD under multiple extreme conditions such as high-magnetic field, extreme low temperature, and high pressure. To measure XMCD spectra with high accuracy, it is necessary to optimize the tuning of the relation among the undulator, monochromator, and X-ray phase retarder (XPR) precisely; that is, the undulator gap and the XPR condition must be adjusted according to the X-ray energy. In addition, a helicity-modulation technique, which provides a dichroic signal of less than 0.01% and with a good signal-to-noise ratio, requires a combination of fast switching of the helicity and a phase-sensitive (lock-in) detection system. Therefore, extremely high-quality XMCD spectra are obtained in a short acquisition time.
  In this study, you can understand polarization control using XPR and the basis of the helicity-modulation method.

The Fresnel zone plate (FZP) is a focusing/imaging optics widely used in the x-ray region. The FZP for x-rays is fabricated by recent nano-technology, and a few tens nm probe size has been achieved using FZP focusing optics and the third generation synchrotron radiation light sources.
