The new ion beam analysis facility of the University of Cologne — •Thomas Materna, Petra Kudějová, and Jan Jolie — Institut für Kernphysik, Universität zu Köln, Zülpicher Str. 77, D-50937 Köln

The new ion beam analysis (IBA) facility is situated at the 10-MV tandem accelerator of the Nuclear Physics Institute of the University of Cologne. It is dedicated to non-destructive atomic and nuclear techniques aiming 1) to determine probe composition, major and trace elements, with very low detection limits (PIXE and PIGE), 2) to determine depth profile information (RBS). The facility includes a fast scanning system allowing the determination of a two dimensional map of the major elements contained in the sample. The scanned area can be as big as 6x6 cm² and the beam size can be reduced to below 1 mm². Another feature of this facility is that the spectra are acquired using digital electronics.
