More Information: To this purpose the existing PIXE set-up installed at the +45° external collimated beam line of the 3 MV Tandetron accelerator of LABEC laboratory was upgraded for Total –IBA measurements. The set-up includes two X-ray detectors for PIXE, a 10 mm2 Silicon Drift Detector (SDD) for light and major elements analysis and a 80 mm2 Si(Li), for heavy and trace elements; one particle detector for EBS/RBS, a Si pin diode 10×10 mm2 active area, placed at 135° scattering angle and mounted in an aluminium case, kept at 10-1 mbar pressure; and one gamma-ray detector for PIGE, a 20% relative efficiency HPGe detector with a mechanical cooler. Quantitative results are obtained by accurate charge-equivalent normalisation measuring the extracted beam weak currents using a rotating chopper [1]. M. Chiari et al., Nucl. Instr. Meth. B 188 (2002) 162-165.
