CALIBRATION

The calibration of accelerators, analytical geometry, and detectors is an essential steps necessary to achieve an accuracy <10% in any ion-beam analysis. The voltmeters of electrostatic accelerators are accurate to about 1%, not enough for the strong energy dependence of Rutherford backscattering, nuclear resonance analysis, or high resolution analysis. Furthermore, magnet power supplies drift over the operational time leading to offsets in their deflection. In the worst case drifts of magnetic field and beam energy compensate each other leaving you completely blind for a beam energy variation.


According to the latest scientific results and international recommendations of best practice, we apply NMR Magnetometers and nuclear resonance techniques for a reproducible calibration down to 1-2 keV. In addition to the beam energy calibration, we also calibrate your detectors for RBS, NRA, PIXE, and PIGE. A combination of nuclear decay sources and properly selected reference materials enables a calibration via a combination of equation systems and nuclear resonance edges, depending on your preferred beam energy range.


This analysis reveals drifts and the weak parts in your setup. Even more importantly it will improve your accuracy and ease data analysis. Our own systems and data analysis tools rely on these extensive procedure to reach their exceptional accuracy and automatisation.
