Upgrade of a 30 kV/10 mA anode power supply for triode type gyrotron

Stefano Alberti, Jean-Philippe Hogge, Damien Fasel, Ugo Siravo, Jérémie Dubray, Philippe Marmillod, Albert Perez, Blaise Marlétaz

The RF power of a gyrotron with a triode type magnetron-injection-gun (MIG) can be directly controlled via the voltage applied between its anode and its cathode. Hence, the performance of this type of gyrotron relies directly on the possibilities offered b ...
