PIXE laboratory

High sensitivity conventional and external beam PIXE setup


The setup is established on the 5 MeV EG-2R Van de Graaff accelerator of KFKI RMKI. The IN-AIR PIXE is combined with a versatile positioning stages for sample objects varying from grams up to 10 kgs.




Scanning proton microprobe


The scanning proton microprobe is installed at the 5 MV Van de Graaff accelerator of the KFKI Research Institute for Particle and Nuclear Physics. It is an upgraded version of the Hamburg MP dismantled in 2001. The probe forming system includes a pair of focusing quadrupoles and an additional quadrupole pair in front of it, which is applied to increase the proton beam divergence. The fine focusing is performed by a computer controlled procedure optimizing the contrast of the secondary electron image of a hexagonal copper grid.
