 note = {In 2000, a micro-beam scanning particle induced X-ray emission (PIXE) analysis system was installed in NIRS. This system provides the ability of multi-elemental mapping on maximum 2.5mm * 2.5mm area in a spatial resolution of about 1MUm with quadrupole triplet magnets and a scanning coil. The estimated beam size on good tuning was 0.40 *0.65 MUm2 that is one of the best capacities of micro-beam scanning PIXE system in the world. The performance was tested using small biological samples such as fish scale, pollen and small fish eye. Fine elemental maps were obtained in the samples of about 30 MUm to a few mm size in the special resolution of about 1 MUm.},
