Abstract
Ion-beam-induced luminescence/fluorescence analysis techniques are analytical methods that can be simultaneously used with particle-induced X-ray emission analysis, a method to analyze trace element compositional distributions. The information obtained from the ion-beam-induced luminescence or fluorescence is diverse. It is correlated with the chemical morphology and biochemistry of the sample under consideration. To reveal these correlations, two spectral mapping systems have been developed to analyze the ion-beam-induced luminescence and fluorescence. Both systems use a charge-coupled-device-based spectrometer and a photon-counting detector. By improving the detection efficiency of the optics, ion-beam induced-luminescence and fluorescence analysis using a nuclear ion beam microprobe can be investigated and further developed. The objectives of this study were to develop dedicated optics and to establish an experimental system to enable analysis using a nuclear ion beam microprobe. Using a 4.5 MV dynamitron accelerator microbeam line at Tohoku University, a new ion-beam-induced luminescence and fluorescence analysis system was constructed. The newly designed optical system enables better detection capability of the ion-beam-induced luminescence and fluorescence owing to the fast response of the photon counter monochromator with a photomultiplier array for wavelength-dispersive analysis. It also enables an improved signal-to-noise ratio of the imaging capability owing to the detection of the fluorescence caused by the proton microbeam. The ability of the system to perform spectral mapping using particulate phosphors was also evaluated.
