PIGE is part of nuclear reaction analysis (NRA) technique. Nuclear reactions of the incident ion with the nucleus of the target atom emit photons (gamma-rays) or charged particles. PIGE only measures the gamma-rays and is of high interest for the detection of low-Z elements. Some low-Z elements can also be detected by PIXE but the information depth is deeper for PIGE. Elemental maps can be recorded to display the distribution of elements.

The Oxford type scanning nuclear microprobe is operated at one of the beamlines of our particle accelerator. The beam diameter is about 1-3 microns for the usual applications in vacuum. The microprobe is equipped with a 5-axis goniometer (X-Y-Z translations and two rotations, to move the sample into the required position), optical microscope, cameras and...
