Description
The Bonn Isochronous Cyclotron provides light ion beams with a charge-to-mass ratio Q/A ≥ 1/2 and kinetic energies below 14 MeV per nucleon to one of five experimental sites. It is planned to extend the facility’s analytic capabilities through the development and installation of an ion beam material analysis setup.
It is intended to use low energy alpha particles with energies between 2 and 5 MeV, with investigations on whether to achieve this through a higher harmonics mode of the cyclotron or energy dispersive elements in the beamline currently under way.
The analytic methods will be Rutherford backscattering (RBS), which is a method sensitive to the mass of a nucleus, and particle induced x-ray emissions (PIXE) which is used to detect characteristic x-ray emission lines to disambiguate isobars.
The experimental setup is currently in development and will house a surface barrier detector (SBD) for RBS, a small number of SBDs for beam characterization and a silicon drift detector for PIXE measurements.
This contribution will give an overview over the development process, some preliminary detector tests and a preparatory benchmark x-ray measurement.
