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

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

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

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

5MW CW supply system for the ITER gyrotrons Test Facility

Damien Fasel, Albert Perez, Ugo Siravo

ECH (Electron Cyclotron Heating) for ITER will deliver into the plasma 20 MW of RF power. The procurement of the RF sources will be shared equally between the three following partners: Europe, Japan and Russia. Moreover, Europe decided to develop a RF sour ...

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

Damien Fasel, Albert Perez, Ugo Siravo, 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 ...
