ITER Organization

ITER Organization in Cadarache

The ITER Organization brings together people from all over the world to be part of a thrilling human adventure in southern France—building the ITER Tokamak. We require the best people in every domain. We offer challenging full-time assignments in a wide range of areas and encourage applications from candidates with all levels of experience, from recent graduates to experienced professionals. Applications from under-represented ITER Members and from female candidates are strongly encouraged as the ITER Organization supports diversity and gender equality in the workplace.

ITER Organization (IO) is an Equal Opportunity/Inclusive organization committed to diversity in the workplace, with diversity and Inclusiveness being one of the ITER Values.

As IO attracts and retains people coming from a vast array of different backgrounds and cultures, bias and exclusion cannot be tolerated. IO believes it is our diverse perspectives and backgrounds that gives unique strength and value to the ITER mission, regardless of race, member nation, gender, religion, status, sexual orientation, or disability – all are welcome and respected at ITER. Our working environment is truly multi-cultural, with 29 different nationalities represented among staff. The ITER Organization Code of Conduct gives guidance in matters of professional ethics to all staff and serves as a reference for the public with regards to the standards of conduct that third parties are entitled to expect when dealing with the ITER Organization. The south of France is blessed with a very privileged living environment and a mild and sunny climate. The ITER Project is based in Saint Paul-lez-Durance, located between the southern Alps and the Mediterranean Sea—an area offering every conceivable sporting, leisure, and cultural opportunity.

Department: Engineering Design Department

Division: Heating & Current Drive Division

Section: Ion Cyclotron Section

Group: Not applicable

Job Family: Engineering

Job Role: Engineer – 3

Job Grade: P3

Language requirements: Fluent in English (written & spoken)

Contract duration: Up to 5 years


As a Mechanical Engineer, you will be responsible for the integration of the transmission line components for the Ion Cyclotron (IC) system in the RF Building, Assembly Hall, Tokamak Building and specific components related to the integration of IC systems such as building penetrations, nuclear shielding or specific auxiliaries. Your tasks will include the management of design and procurement of IO Bioshield and support the procuring Domestic Agency (DA) on the design finalization and preparation of technical specifications for external contracts. The post will also support the installation and metrology follow up, system requirements and subsequent oversight of the activities leading to installation, commissioning, testing and operation of the IC system.


The IC system will be used at ITER for Heating and Current Drive (H&CD) in a number of plasma operating scenarios, providing 20MW of power to the plasma by means of two antenna installed in the equatorial ports. There is a possibility of potential upgrade for an additional 20MW (40MW in total) of delivered power. This system aims to increase the energy content in the plasma to assist fusion operation and control internal plasma parameters. The IC H&CD system consists of two broadband equatorial port plug antennas, their pre-matching and matching systems, transmission lines, Radio Frequency (RF) Sources and High Voltage Power Supplies. The RF sources include 18 amplifier chains and 9 combiners, which together constitute 9 sources that can provide each up to 3MW for 3000 seconds in a frequency range of 40-55MHz to a matched load. The transmission lines and matching system are designed and procured by the US Domestic Agency and will be installed by the IO in the RF, Assembly, Tokamak and Hot Cell buildings. It is a large network with around 1100 m of 300 mm diameter rigid coaxial lines and approximately 300 90º elbows. The layout in the RF building allows interconnecting the RF sources with the 8 main transmission lines, the 2 power dummy loads and the test line connected to the Port Plug Test Facility in the Hot Cell Facility.
