Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Lead the operation and technical development of the Linac3 ion source to ensure high-performance delivery of heavy ion beams. Coordinate maintenance activities, supervise a multidisciplinary team, and contribute to the design of upgrades for the CERN ion injector complex.
Requires a Master's or PhD in Applied Physics, Engineering, or a related field with demonstrated experience in particle source design or operation. Must have hands-on experience with high-voltage equipment, microwave generators, and multi-particle simulation codes.
At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.
Within the Beam department (BE) and the Accelerator and Beam Physics group (ABP), join the Hadron Sources and Linacs section (HSL) at CERN as a lead applied physicist overseeing the Linac3 ion source, a role bringing together multiple physics domains coupled with beam dynamics, including high voltages, high magnetic fields, plasma heating with microwaves, the delivery of gases and vapours into vacuum systems as well as x-ray generation and shielding. You will ensure the high-performance delivery of heavy ion beams, driving both daily operations and long-term technical development of the system providing particle beams for one of the world's most unique accelerator complexes, serving fixed-target users and the LHC.
Master's degree or PhD or equivalent relevant experience in the field of Applied Physics, Engineering or a related field.
Spoken and written English, with a commitment to learn French.
