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 ...

Supply equipment to the new NBH system for the TCV tokamak

Alexander Karpushov, Damien Fasel, Ugo Siravo, Jérémie Dubray, Albert Perez

The TCV tokamak is equipped with a high power real time-controllable Electron Cyclotron Heating (ECH) system, made of 9 gyrotrons capable of 500 kW RF power. One of the major scientific challenge, the TCV upgrades aimed to, will be the access to a wider ra ...

Upgrade of the TCV tokamak, first phase: Neutral beam heating system

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Timothy Goodman, Yves Martin, Stefano Alberti, René Chavan, Alexander Karpushov, Damien Fasel, Matthieu Toussaint

Experiments on TCV are designed to complement the work at large integrated tokamak facilities (such as JET) to provide a stepwise approach to extrapolation to ITER and DEMO in areas where medium-size tokamaks can often exploit their experimental capabiliti ...

MAGY: an innovative high voltage - low current power supply for gyrotron

Damien Fasel, Ugo Siravo, Albert Perez, Mauro Carpita

From the electrical point of view, the body and the anode of high power gyrotrons behave as capacitive loads. A highly dynamic power supply is, therefore, hard to achieve. The MAGY concept (Modulator for the Anode of a triode type GYrotron) embodies an inn ...
