Nuclear Microprobe and Detector Testing
Nuclear microprobe beamline at the Ruđer Bošković Institute in Zagreb
In the high current operation mode case needed for the ion beam analysis, PIXE and/or RBS is operated by proton or He ion beam. For the ion beam analysis and of light isotopes, a nuclear reaction analysis (NRA) is being used; often this is done by He3 ion microbeam. Typical spot sizes in the high current mode can be as low as 1 m.
In the low current operation mode of the nuclear microprobe (ion beam currents < fA) techniques such as STIM (scanning transmission ion microscopy) and IBIC (ion beam induced charge) are used. IBIC technique is used for imaging of transport properties in radiation detectors and other electronic devices. Ion microbeam can in that case be used for in situ study of materials radiation hardness or creation of single event upsets in electronic circuits. For the most favourable conditions the beam spot size of the low current mode can be as low as 250 nm.
