A small and compact AMS facility for tritium depth profiling

Depth profiling measurements of tritium at carbon samples have been performed during the past seven years at the AMS facility installed at the Rossendorf 3 MV tandetron. The samples have been cut from the inner wall of the fusion experiments ASDEX-upgrade/Garching and JET/Culham. The increasing amounts of tritium inside the samples from JET have been required a dedicated AMS facility to prevent any contamination of the versatile 3 MV tandetron. On base of an air-insulated 100 kV tandem accelerator equipped with a gas stripper a small dedicated AMS facility for tritium depth profiling was installed, tested and used for routinely measurements. After successful tests of diamond-like carbon (DLC) stripper foils at this accelerator a small and compact SF6-insulated 100 kV tandem accelerator with a DLC-stripper has been installed at the AMS facility. Results measured with the different tandem accelerators are presented.
