Application of laser produced ion beams to nuclear analysis of materials

The ion beam driven nuclear analysis has been developed for many years by using various electrostatic accelerators. A proton micro-beam with the beam diameter of similar to 1.5 mu m at Takasaki Ion Acceleration for Advanced Radiation Application (TIARA), JAEA was used to analyze the positive electrode of the.Li-ion battery with PIGE and NNE. WThe RIGE and PIXE images of Li and Ni. respectively for Li-x Ni-0.8 Co-0.15 Al-0.05 O-2 (X = 0.75 similar to 1.0) anodes have been taken. The PIM): images of Li-x Ni-0.8 Co-0.15 Al-0.05 O-2 particles and the depth profile of the Li density have been obtained with high spatial resolution (a few pm). The images of the Li density distribution are very useful for the R&D of the Li ion battery. In order to make the in-situ ion beam analysis of the Li battery possible, a compact accelerator for a high quality MeV proton beam is necessary. Form this point of view, the diagnostics of Li ion battery is an appropriate field for the applications of laser produced ion beams.
