JAERI Takasaki in-air micro-PIXE system for various applications

In JAERI Takasaki, an in-air micro-PIXE system has been developed. This system enables multi-elemental mapping of samples in atmospheric environment with spatial resolution of 1 μm. Various research programs, such as biomedical research, dental study, environmental science and geology, have been started in recent years. Several related techniques for these applications were developed. A FTP server has been operated for the remote collaborators to share experimental data over the internet. We have developed image processing methods for elemental concentration analysis and a new beam monitoring technique in thick target irradiation
