The 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 goniometer (to move the sample into the required position), an optical microscope, cameras, several radiation and particle detectors, providing multi-elemental analysis also on trace element level. For larger or vacuum-sensitive samples, the beam is extracted through a thin window. In this case, the beamsize is about a few tens of microns. The beam is scanned on the sample, which gives the mapping ability, both in vacuum and in air. The maximum scan size is about 2mm x 2mm.
