Bio-PIXE AT THE TAKIZAWA FACILITY (Bio-PIXE WITH A BABY CYCLOTRON)

For the developement of bio-PIXE, two problems remain to be solved; one in accelerator availability and the other in data analysis. To improve the former, a method of applying baby cyclotrons to PIXE has been developed. To solve the latter, the computer program SAPIX for x-ray spectrum analysis ,which runs on ordinary personal computers and is fairly easy to operate has been developed. Examples of spectral fitting by the SAPIX and a description of the program are given. Further, the two-detector measuring system which we have employed for the simultaneous determination of all elements is reported.
