An Ion micro-Beam Induced Luminescence (micro-IBIL) and micro-PIXE combined system for chemical-state analysis was newly developed on a micro-beam facility of single-ended accelerator at JAEA Takasaki TIARA. The photons caused by an ion impact have much information about the chemical state of the target in its wavelength. Therefore the proposed micro-IBIL system had developed by using a monochromator and a photon-counting system to observe photon intensity at specific wavelength range. A photomultiplier in the photon-counting system was cooled by a peltier device to reduce the background noises down to 10 cps. Quite weak photon signals were able to be observed by the proposed system. 3-MeV proton irradiation experiments were performed to obtain micro-IBIL photons from the target. IBIL photon signals from the silicon dioxide in target aerosol particles had been successfully measured by the proposed micro-IBIL System.

The details are not understood though it is thought that protists take on specialized roles on the transition of radioisotopes in soil. In this study, the three-dimensional distribution of Pb in a cell of 
in water including Pb was tried to measure with micro-PIXE and ML-EM (maximum likelihood expectation maximization) algorithm. As a result, it was found that the distribution of Pb was limited on the surface of the cell.

Cognitive degradation and behavior disorder occur under the mental disease caused by stimulant drugs. In this study, it was continuously administered to mice. After that, neuropoiesis of dentate gyrus and trace elements in its brain were analyzed by in-air micro-PIXE. As a result, the distribution of trace elements was different from that of normal mice.
