ESS is at an exciting turning point. It is in transition from being a construction site, to being an operating facility. To help us realise our goal of being the most powerful neutron source in the world, we are now looking for a RF cavity scientist or engineer to join the Linac Group to support the operation, maintenance and development of the normal-conducting and superconducting cavities of the ESS linear accelerator.

In this role, you will be working within a team of technicians and engineers. The ESS linac accelerating elements include an RFQ, 3 buncher cavities, a 5-segment drift-tube linac, 26 double spoke cavities and up to 120 elliptical cavities of two different families (medium beta and high beta). All of the normal conducting front-end, the spokes and 56 elliptical cavities are already installed for the staged commissioning of the facility at 2 MW power. Commissioning with low power beam is under way, and operation with higher beam power is planned to start in 2026 – when the protons can be sent to the spallation target.
