Fellowship at CERN: Ionisation cooling

Your responsibilities

Are you passionate about accelerator physics and eager to tackle one of the biggest challenges in future collider technology? Join the Accelerator and Beam Physics group and become a part of the International Muon Collider Collaboration (IMCC). Contribute to groundbreaking research on collective effects during ionisation cooling—a crucial step in delivering high-brightness muon beams.

As an Applied Physicist in this exciting field, you will:

• Investigate collective effects that may impact ionisation cooling and the generation of high-brightness muon beams.
• Study beam interactions with electromagnetic wake fields in absorbers, gas-filled RF cavities, and other materials.
• Analyze the effects of ionisation-induced charge pairs and their impact on beam stability.
• Develop theoretical models and simulations to explore instabilities in the cooling process.
• Collaborate with leading experts in the IMCC, contributing to the future of muon collider technology.

Your profile

Skills
