 note = {In March 1999, we installed an accelerator in the Electrostatic Accelerator Building for PIXE (Particle Induced X-ray Emission) analysis. The accelerator facility incorporates three beam lines for conventional, in-air and scanning microbeam PIXE analysis. The scanning microbeam PIXE analysis system provides the ability of multi-elemental mapping over sample areas up to 2 x 2mm area with spatial resolutions routinely at 1 micro meter. The scheduled operation of this facility started in April 2000. The result of beam resolution tests carried out in 2001 are as follows: For Scanning Transmission Ion Microscopy (STIM), the estimated beam size is 100 x 200 nm. For PIXE operation at 50 pA of beam current, the estimated best spot size is 0.4 x 0.6 micro meters. The micro-beam apparatus is being used for research into the elemental distribution of small biological samples such as biological cells and tissue., ２１世紀連合シンポジウム-科学技術と人間},
