Offer Description

The European Synchrotron, the ESRF, is an international research centre based in Grenoble, France.

Through its innovative engineering, pioneering scientific vision and a strong commitment from its 700 staff members, the ESRF is recognised as one of the top research facilities worldwide. Its particle accelerator produces intense X-ray beams that are used by thousands of scientists each year for experiments in diverse fields such as biology, medicine, environmental sciences, cultural heritage, materials science, and physics.

Supported by 21 countries, the ESRF is an equal opportunity employer and encourages diversity.

The Accelerator and Source Division (ASD) operates an accelerator complex with a 6 GeV electron storage ring, which is the source of the X-rays that are exploited on the experimental stations. In 2020, the ESRF has commissioned a new ultra-low emittance ring that constitutes the world’s first Extremely Brilliant Source (EBS) of hard X-rays. As part of the ASD, the Radio Frequency (RF) group is responsible for the 200 MeV Pre-Injector Linac, the 352 MHz accelerating RF cavities of the booster and the storage ring with their high power RF transmitters, as well as the pulsed magnets and power supplies of the beam injection/extraction systems. The RF group comprises five units with a total of 16 collaborators.

As an engineer in the RF group, within the RF power amplifiers unit, your main tasks will be to :

• Participate in the operation, maintenance, monitoring and upgrading of RF power amplifiers to ensure safe and reliable operation of the accelerator complex.
• Taking an active part in current projects: replacement of the 1.1 MW klystron transmitters with ten 110 kW solid-state amplifiers, implementation of 1.4 GHz solid-state amplifiers for the new 4th harmonic RF system for cluster extension.
• RF characterization and tuning of passive components using a vector network analyzer
• RF design, prototyping, characterization and optimization of active RF components, in particular RF amplifier boards.
• Actively participate in technical and scientific exchanges and collaborations at a global level within the accelerator community.

In addition, as a member of the Accelerator and Source division, you will be required to contribute 15% of your time to the operation of the accelerator complex as part of the shift work for the user service and take part in the RF standby duty.
