Low-level RF-Engineer

Paul Scherrer Institut; Schweiz; Hybrid; EUR 96.000 - 138.000; Vollzeit

Zusammenfassung

The Paul Scherrer Institute (PSI) invites applications for a Low-level RF-Engineer to design and validate control algorithms for multi-bunch operation in travelling-wave RF structures. Work includes modeling RF systems, developing automation tools, and contributing to LLRF architecture within SwissFEL projects.

Candidates should hold MSc/PhD in Physics, EE, CS or related field, with strong background in control theory, beam dynamics, and Python/MATLAB programming.

Qualifikationen

• MSc or PhD in Physics, Electrical Engineering, Computer Science, or a related field
• Strong background in feedback control theory and automation of complex systems
• Foundational knowledge of beam dynamics in linear accelerators
• Experience with LLRF systems or EPICS-based control systems is an asset
• Proficiency in Linux environments and programming (e.g., Python, MATLAB); experience with FPGA firmware is a plus
• Familiarity with system and/or software engineering practices is advantageous
• Demonstrated problem-solving mindset, hands-on approach, and excellent command of English

Aufgaben

• Design and develop advanced control algorithms for multi-bunch operation in travelling-wave RF structures, with a focus on 4-bunch schemes for FCC-ee and experimental validation using 2-bunch configurations at SwissFEL
• Perform modeling and simulation of RF systems and beam acceleration to support control strategy development and operational studies
• Create automation tools to efficiently configure, optimize, and stabilize multi-bunch beam operation
• Contribute to the systems engineering of LLRF systems, translating user requirements into integrated hardware, firmware, and software architecture
• Support and gain hands-on experience in the operation and optimization of the SwissFEL LLRF system
