The RIKEN Materials Science Beamline at SPring-8: Towards Visualization of Electrostatic Interaction

In order to visualize molecular interaction by the experimental electrostatic potential analysis we have optimized the optical parameters and developed the high-resolution Debye-Scherrer camera at the RIKEN materials science beamline, BL44B2 of SPring-8. For the purpose the camera was designed to be equipped with the hybrid X-ray detector system. One is the conventional detector, the imaging plate readout off-line to carry out high d(interplanar spacing)-resolution measurements and the other is the CCD detector, which can be operated in a camera at variable distances for high angle-resolution measurements. In addition we have been developing an in-situ properties measurement system to visualize the electrostatic interaction completely synchronized with material functions.
