This article addresses the computer control and data analysis system in "SPEED-1500", a Kawai-type multi-anvil press installed on beamline BL04B1 at the SPring-8, which is for X-ray diffraction and radiography experiments by means of synchrotron radiation. The system consists of several different computer applications, which are for pressure and temperature control, stage and goniometer control, and data-collection and its analysis. These programs have been used by many public users and are still improving.

The epitaxial growth of high quality TiO films has attracted much interest from the viewpoints of basic science and applications. In the synthesis process of TiO films, the pulsed laser deposition (PLD) method is widely employed because of its advantage for materials with high melting point. The laser irradiation generates plasmas from Ti bulk targets, and the evaporated Ti particles have interactions with buffer dioxide gas before/after the epitaxial growth. We observed the optical emission spectra from the plumes generated by laser ablation in order to improve on the epitaxial growth under proper conditions. The spectra show dependences of energy densities and wavelengths of the laser. The spectra are investigated for relevancies to the quality of films and crystallographic relationships that were assessed by x-ray diffraction, x-ray pole figures and Rutherford backscattering spectroscopy.
