Improvement on experimental procedure of various samples in PIXE analysis

Abstract

Standard experimental procedures of PIXE in NMCC are described. We are engaged in researches on PIXE analysis and PET study by use of a small cyclotron in collaboration with CRC. The facilities are opened to scientists in Japan. As the research fields of the scientists are very wide, many kinds of samples are analyzed by PIXE. We established standard experimental procedures for those various samples. Preparation of the samples must be easy and simple to minimize risks of contamination and nonuniformity. We usually use silver nitrate or indium salt as an internal standard. Specific absorbers are often used to attenuate X-rays from a major matrix in specific samples.
