A small and compact AMS facility for tritium depth profiling
Research output: Contribution to journal › Article
A dedicated AMS facility for depth profiling of tritium in carbon samples has been installed, tested and applied to routine measurements in the Forschungszentrum. Rossendorf. It is based on an SF6-insulated 100 kV tandem accelerator equipped with a thin diamond-like carbon (DLC) stripper foil of about 1 mug/cm(2). With this setup carbon samples with tritium concentrations in the range of 5 x 10(10)-10(19) atoms/cm(3) can be analysed. In first routine measurements carbon samples cut from tiles of the inner wall of the fusion experiments ASDEX-upgrade Garching/Germany, JET Culham/UK and TFTR Princeton/USA have been analysed. In addition, depth profiles of deuterium and other light elements can be measured using the Faraday cup at the entrance of the accelerator (SIMS mode of the facility) or in the case of very low concentrations after acceleration using a particle detector (AMS mode).
