Abstract

The high heat flux ion beam test facility at Forschungszentrum Jülich can produce peak power densities of 0.14 to 12 kW/cm2 for pulse lengths of 10 ms to 15 s. Longer pulses up to steady-state operation are possible with reduced power. The total ion beam power can be varied between 70 kW and 6 MW at particle energies of 10 to 60 keV. The particles are hydrogen and helium. The beam illuminates an area of 1300 cm2, which allows a large area for materials tests. The rise time of the beam pulses can be adjusted between 2 and 200 ms, and the pulse repetition rate is between 1 and 5 min. The test facility is equipped with a sample manipulator with a vacuum lock that allows a sample size of 15 x 10 cm with active or passive cooling. The extensive diagnostic system of the test stand and the diagnostic system of the sample manipulator are described. The results of a materials test series performed for the development of wall materials for NET/ITER are shown. Possible up-grades of the facility are also discussed.
