Special tests on the first unit of the solid-state RF amplifiers for the ITER HNB and the NBTF experiments

Lessons learned after three years of SPIDER operation and the first MITICA integrated tests

“…The above-mentioned evidences led to the decision to replace the RF generators in SPIDER and MITICA and change the current ITER baseline from self-excited free running tetrode oscillator technology to solid-state amplifier technology [17,23,24]. The solid-state amplifier technology is believed to be strongly attractive for ion source operation, since no frequency flip phenomena are expected and there are no tetrodes requiring high voltage.…”
