Job description

You will join a multidisciplinary team developing the next generation of high-performance superconducting radiofrequency (SRF) cavities. In this role, after dedicated training in the team, you will develop and optimise advanced surface treatments essential to their performance, including chemical polishing, electrochemical polishing and electroplating. You will also contribute to the design, procurement, commissioning, and acceptance of a new surface treatment facility dedicated to SRF components.

Your responsibilities

• Develop, operate and optimise chemical and electrochemical surface-processing techniques for SRF accelerating cavities and their subassemblies.
• Optimise existing processes by developing and conducting laboratory-scale chemical and electrochemical trials, applying multiphysics simulation tools to improve process performance and reproducibility.
• Define technical requirements and coordinate the design, procurement, testing, commissioning and acceptance of new equipment and facilities for the chemical and electrochemical surface finishing of SRF components.
• Develop, validate, document and implement operating procedures, process specifications and quality control methods for the surface finishing of SRF components.
• Work closely with engineers, physicists, technicians, safety specialists and external suppliers, communicating results and technical recommendations through reports, reviews and project meetings.
• Ensure that all necessary safety measures and documentation are kept up to date and effectively implemented across existing and new processes and facilities
