High heat flux ion beam test facility for material research and development
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.
