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 ...

Passive UHF RFID Systems for Capacitive Sensing Applications

Kerem Kapucu

In this work, a complete passive UHF RFID system for capacitive sensing applications is developed to be used in food quality monitoring and supply chain management. All the components of the RFID system including the base station, the base station antenna, ...

Moment-based, self-consistent linear analysis of gyrotron oscillators

Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Trach-Minh Tran

A new model for simulating gyrotron oscillators in the monomode time-dependent linear self-consistent regime is presented. Starting from a nonlinear time-dependent monomode model, the linearization and the following simplification of the model, based on a ...

Design of a Passive UHF RFID Tag for Capacitive Sensor Applications

Catherine Dehollain, Kerem Kapucu

In this work, the design of a passive UHF RFID tag for sensor applications is described. The system level design issues are discussed taking into account the possible operation scenarios. Among the blocks in the tag, the emphasis is on the design of the re ...

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 ...

Gyrotron parasitic-effects studies using the time-dependent self-consistent monomode code TWANG

Stefano Alberti, Jean-Philippe Hogge, Trach-Minh Tran, Fengping Li

Parasitic effects have recently appeared to be a potential limiting factor for reliable operation of high-power high-frequency gyrotrons. Within the domain of validity of a self-consistent monomode model, the time-dependent code TWANG has been developed wi ...

IEEE2011

This paper is focused on the design, modulation and control of a re-generative non-symmetrical multi-level converter for high-power applications such as oil and gas or mining. The converter is based on standard IGBT modules and the DC-link voltages are cho ...

First experimental results from the EU 2 MW coaxial cavity ITER gyrotron prototype

Timothy Goodman, Stefano Alberti, Minh Quang Tran, Jean-Philippe Hogge, Laurie Porte, Damien Fasel, Ugo Siravo, Emmanuel Droz

The EU is working towards providing 2 MW, coaxial-cavity, CW, 170 GHz gyrotrons for ITER. Their design is based on results from an experimental pre-prototype tube in operation at FZK for several years, having a pulse length of several milliseconds. The fir ...
