Self-powered detectors for test blanket modules in ITER

Self-powered detectors are under test for application as neutron and gamma flux monitors in ITER test blanket modules. This paper presents the experimental setup designed for the first tests with flat sandwich-type detectors, based on beryllium and vanadium emitters. Results from the irradiation experiments with 14 MeV neutrons are shown. A preliminary understanding of the signal-creation mechanism for the tested detectors is discussed and future plans are outlined.
