Digital electronics engineer

Context & Job description

The ESRF’s Radio Frequency (RF) group designs, operates, and maintains instrumentation essential for increasing and stabilizing electron energy in the accelerator complex. To enhance the performance of the storage ring, the group is developing a digital Low-Level RF (dLLRF) system, featuring a fast RF feedback system to control both existing accelerating cavities and new harmonic cavities. In this context, we are looking to strengthen our team with a Digital Electronics Engineer.

Main Missions

• FPGA & Digital Electronics Development: Lead the construction and validation of the new dLLRF system based on Micro Telecommunication Computing Architecture (MicroTCA).
• System Adaptation: Adapt the dLLRF system developed at SOLEIL Synchrotron to meet ESRF’s requirements, as part of a collaborative agreement.
• Data Logger Development: Design and implement a fast data logger for post-mortem analysis of RF signals.

Key Responsibilities

• Finalize and validate architectural choices for the new dLLRF system.
• Develop the application framework (FPGA firmware), including optical communication links between modules to configure the fast-digital RF feedback system.
• Study, compare, implement and test digital regulation algorithms for the project.
• Complete the implementation, testing, deployment and documentation of the final dLLRF system in the accelerator complex.
• Participate in shift work as per ESRF regulations.
