New PIXE in-air setup at the 10 MV FN-Tandem accelerator — •Ilias Alexandridis, Markus Schiffer, and Dennis Mücher — Institute for Nuclear Physics, University of Cologne, Germany

In order to determine the material composition of geological and ar- chaeological samples studied by different groups at the University of Cologne, a PIXE in-air setup will be installed at the FN-Tandem accel- erator of the Institute of Nuclear Physics. Here, the X-rays induced by irradiation with ionized particles are measured using an SDD(Silicone- Drift-Detector) detector. Conclusions can be drawn about the atomic components of the sample from the characteristic x-rays present in the spectrum. As a non-destructive measurement method, PIXE is partic- ularly suitable for the intended samples. The measurement in air also allows for a large number of potential samples to be measured while minimizing the amount of beamtime being spend. In this contribution we will present the new setup and first measurements of elementary metal samples.
