Radio Frequency Solid-State Amplifiers (RFSSA) will replace the oscillators supplying SPIDER, MITICA and the ITER HNB RF ion sources. In order to verify the operation of the amplifiers on a significant load for the appli-cation and to identify possible integration problems in advance, special tests on a Resonant Dummy Load (RDL) able to mimic the ion source characteristics were foreseen. This paper will present the RDL conceptual design and the special tests that will demonstrate the design and operation of the RFSSA first unit in normal and abnormal conditions, and its integration to mitigate risks before on-site commissioning.
In a world increasingly facing new challenges at the forefront of plasma scientific research and technological innovation, CNR and ISTP pledge progress and achieve an impact in the integration of research into societal practices and policy
