Uppsala University joined the RADIATE project on 1 April 2021 as a full project partner and is supporting the consortium’s transnational access activities. The Tandem Laboratory at Uppsala University will provide approximately 600 hours of transnational access.

At the tandem laboratory, the following facilities are accessible for external users:

  • A 5 MV pelletron accelerator system with in total 6 beamlines and 9 end-stations which can be used for all types of standard IBA, such as RBS, PIXE, foil & ToF-ERD, channeling and NRA several of which in multiple end-stations, optimized both for high sample throughput and for large custom samples. The laboratory also features a μ-beam facility. The system also holds a set-up for thin film growth, annealing and keV ion implantation which permits simultaneous in-situ ion beam analysis using several IBA-methods. The accelerator also features an AMS-beamline mainly used for radiocarbon and Be, but also capable of analysis using other radionuclides.
  • A 350 keV high-current implanter is used for ion implantations for a wide range of species for targets up to 6 inch and at elevated temperatures. The same accelerator acts also as an ion source for a low-energy IBA system featuring RBS, PIXE, NRA and channeling. Finally, the system also feeds a world-unique ToF-ERDA system, which can be used for high-resolution depth profiling using a wide variety of primary ion energies and species, as well as different geometries, even enabling transmission experiments. The system is also capable of in-situ analysis during annealing.
  • A 200 kV compact tandem system (MICADAS provided by ETH Zurich) serves as basis for the majority of the radiocarbon dating services provided for external users. The system can be feed with graphitized samples and gas.
    Finally, a time-of-Flight Low-energy ion scattering system connected to a multipurpose growth and analysis chamber offers to study near-surface properties of materials with a resolution not accessible for the other systems.

  • ToF-ERDA analysis using 2 different set-ups optimized for high sample throughput & large flexibility in sample dimensions respectively. The 5 MV tandem accelerator offers large flexibility in choice of the primary ion species and energy, allowing also for heavy primary ions such as iodine or Au at sufficiently elevated energies.
  • NRA for high-resolution depth profiling of hydrogen using 15N primary ions.
  • ToF-MEIS for high-resolution depth profiling, with the option of in-situ thermal treatments
  • ToF-LEIS for high-resolution depth profiling, with the option of in-situ thermal treatments
  • In-situ IBA offering RBS, ERDA, PIXE & NRA in combination with thermal annealing, sputtering, thin film
    deposition and gas exposure
  • Irradiation station for MeV ions
