PhD High-Intensity Electron Sources for Future Accelerators

Immigration Policy Lab; Zürich; On-site; CHF 65,000 - 75,000; Full time

Benefits offered by this job

ETH Doctoral Programme enrollment

Teaching and mentoring opportunities

Job summary

ETH Zurich seeks a Doctoral candidate to work on high-intensity electron sources for future accelerators, based at PSI Villigen with teaching duties at ETH Zurich. The project combines beam/plasma physics, RF technologies and high-power lasers to advance beam shaping for FCC and SwissFEL+ applications.

You will commission a new electron source test stand, compare laser-shaping techniques, and explore AI-based optimization, with opportunities to contribute to groundbreaking accelerator research

Qualifications

• Master's degree (or equivalent) in physics, accelerator science, electrical engineering, photonics, or a closely related field.
• Professional proficiency in English; knowledge of German is an asset.

Responsibilities

• Commission a new electron source test stand and demonstrate pulse-to-pulse modulation of bunch charge, beam size, and laser pulse energy relevant to FCC-ee electron source concept
• Compare laser-shaping techniques through beam measurements, build a prototype for photocathode operation, and investigate machine-learning/AI-based optimization to improve performance
• Study photocathode and laser performance, including the lifetime of semiconductor photocathodes at bunch charges of up to 5 nC
• Measure gains in beam brightness from both photocathode laser shaping and RF compression with applications to a SwissFEL upgrade (SwissFEL+)
