Beamline instrumentation

The work horse for ion beam analysis is a versatile RBS/PIXE chamber with a fast sample changer installed at the 0° beam line. The same chamber is used for nuclear reaction analysis and ion implantation. Several meters downstream, a nuclear microprobe with an Oxford Microbeams quadrupole triplet is attached. It is equipped with RBS, PIXE and STIM detectors. STIM and PIXE can also be performed in-air. For this purpose the beam is extracted into air via a glass capillary with a micron sized opening that does not need any vacuum diaphragm. The 30° beamline is hosting a Heavy Ion ERDA system combining a time-of-flight spectrometer with a gas ionization chamber. Good mass resolution is warranted by the use of very thin diamond-like carbon and silicon nitride films. Connected to the same analysis chamber, a Kobe-steel high resolution magnetic RBS spectrometer is being set-up. The MeV-SIMS capillary microprobe attached to the 6 MV Tandem beamline is described in some more detail here.
