⚡ Accelerator Scientist with Expertise in X-Band Technology – Pioneer Energy Compression for PETRA IV at DESY, Hamburg

DESY – one of the world's leading research centres with over 2,900 employees across Hamburg and Zeuthen – is pushing the boundaries of laser-plasma accelerator (LPA) research for health, photon science, and particle physics. We need a driven scientist to design and build an energy compression beamline for the next-generation PETRA IV plasma injector, a cornerstone of our future research infrastructure.

Your Role

• Shape the development of the PETRA IV plasma injector from concept to prototype
• Review and refine the x-band based dechirper design, challenging assumptions where needed
• Partner with DESY groups, suppliers, and international labs to source, integrate, and test x-band hardware
• Run feasibility studies and propose alternative RF technology routes when the current design falls short
• Build and commission a prototype energy compressor for GeV-class LPA electron beams

What You Bring

• PhD in physics with a focus on accelerator physics or an equivalent qualification
• A solid track record in accelerator physics and deep RF technology knowledge, ideally in x-band
• Hands-on experience with simulation tools such as elegant for beam-dynamics modelling
• Practical experience in constructing and commissioning accelerators
• A proven ability to steer complex, multi-stakeholder research projects
• Background in plasma acceleration is a strong plus
• Fluent English and a genuinely collaborative working style
