Abstract

A new PIXE facility combined with a small cyclotron (alias Baby Cyclotron) established exclusively for medical use is described. Sufficient amount of 2.9-MeV protons can be extracted from the cyclotron by accelerating H₂⁺-ions with acceleration parameters for 8.3-MeV deuterons. Some technical problems for applying the cyclotron to PIXE analysis, such as elimination of deuteron contamination from proton beams and radiation shielding of the PIXE room during radioisotope production in the cyclotron vault, are reported.
