Assistant/Associate RF Researcher

Brookhaven National Laboratory (BNL) is the building site for the Electron‑Ion Collider (EIC), a one‑of‑a‑kind nuclear physics research facility. The EIC will be a discovery machine for unlocking the secrets of the “glue” that binds the building blocks of visible matter in the universe. The machine design is based on the existing and highly optimised RHIC Ion‑Ion collider. It will consist of two intersecting accelerators, one producing an intense beam of electrons, the other a beam of protons or heavier atomic nuclei which are steered into collisions. Beyond sparking scientific discoveries in a new frontier of fundamental physics, the Electron‑Ion Collider will trigger technological breakthroughs that have broad‑ranging impact on human health and national challenges. Position Overview Assistant / Associate RF Researcher in the RF Group, responsible for conceptualisation, design and analysis of normal‑conducting radio‑frequency (RF) cavities and auxiliary components for the EIC Project, and for supporting fabrication oversight, cavity system assembly, verification, installation and commissioning. Responsibilities Conceptualise and design normal‑conducting RF cavity systems for the EIC project, including cavities, power input couplers, parasitic mode dampers, and tuning methods. Perform multi‑physics analysis and studies to provide adequate confidence that the RF cavity system will meet requirements. Document designs, studies, and measurement results. Develop plans and procedures for cavity system assembly, verification, and installation. Support fabrication oversight, assembly, verification, installation, and commissioning of cavity systems and their ancillaries. Contribute to project planning, budgeting, and execution of normal‑conducting RF cavity systems scope for the EIC in collaboration with RF Group leadership and EIC project management. Support the development of superconducting RF (SRF) cavity systems for the EIC project. Required Knowledge, Skills, and Abilities Degree in Electrical Engineering, Physics, or a related field.
