Oral presentation

Development of ion luminescence microscopic spectroscopy analysis and imaging system using ion microbeam probe and aerosol characterization

Kada, Wataru; Sato, Takahiro; Yokoyama, Akihito; Koka, Masashi; Kamiya, Tomihiro

no journal, , 

Microscopic chemical-sate analysis increases its importance in deciding the behavior of materials, especially with the toxic materials in the environment. Conventional PIXE is not applicable to these usage, however, ion-beam-induced photons can be related to these information. In this study, a new IBA technique of Ion Luminescence Microscopic Spectroscopy (ILUMIS) was developed and applied to the analysis and imaging of the several microscopic targets. The results confirmed that ILUMIS is one of the new promised microbeam technique with sensitivity in chemical analysis.

Development of an image reconstruction method for quantitative profiling of $$gamma$$-ray sources at close range using Si/CdTe Compton camera

A conventional $$gamma$$-ray imaging system such as a gamma camera and SPECT has a fundamental problem that imposes a tradeoff between sensitivity and spatial resolution and restricts $$gamma$$-ray energy to low because of the physical constraints resulting from the mechanical collimation. On the other hand, a Compton camera, which applies kinematics of Compton scattering to the electronic collimation, is a next generation $$gamma$$-ray imaging system which decouples the tradeoff between sensitivity and spatial resolution and covers a wide range of energy. We study an application of a Si/CdTe semiconductor Compton camera being developed for space observation to in vivo tracer imaging in medicine and biology. Particularly, it is essential for a medical and biological application to estimate quantitative distribution of tracers in a field close to the camera. We developed an image reconstruction method to realize quantitative profiling of $$gamma$$-ray emitting sources.

Production of platinum nanoparticles using a few ten keV electron beams and application to catalytic reactions

Hakoda, Teruyuki; Isozumi, Yukihiro*; Yamamoto, Shunya; Aritani, Hirofumi*; Yoshikawa, Masahito

no journal, , 

In the present study, the reduction of PtCl$$_{4}$$$$^{2-}$$ ions and subsequent formation of Pt particles were examined for a few tens keV EB irradiation of PtCl$$_{4}$$$$^{2-}$$ ion solution in the presence of 5-20wt% ethanol as an OH radical scavenger. As a result, the reduction of PtCl$$_{4}$$$$^{2-}$$ ions proceeded in whole solution by irradiating only the topmost surface layer of the solution, and these Pt particles with sizes of 2-5 nm would be produced as a primary particle through reduction of PtCl$$_{4}$$$$^{2-}$$ ions. Moreover, these Pt particles was observed to have hydrogen dissociation activity and oxidation activity.
