Superconducting Thin Film Coating Physicist (TE-VSC-SCC-2024-191-LD)

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. Find out more on http://home.cern.

Introduction

Are you passionate about advancing thin-film technologies for superconducting applications? Step into a pivotal role driving innovation in particle acceleration coatings!

CERN operates the largest accelerator complex in the world where particles are accelerated by superconducting radiofrequency cavities. Are you interested in developing new superconducting thin films for a more efficient particle acceleration? Then come and join the Vacuum, Surfaces and Coatings Group! Take part!

The Vacuum, Surfaces and Coatings Group is responsible for all high and ultra-high vacuum systems for the CERN accelerators. Its mandate covers all activities from development to operation, including design, production and procurement, surface engineering and analysis, acceptance tests, control and monitoring. The Surface Coatings and Chemistry section (SCC) takes care of surface and chemical analyses, thin film coatings and surface finishing.

Functions

Within the VSC Group of the TE Department, you will:

• Participate in R&D activities for thin films coating for Superconducting Radiofrequency (SRF) applications at CERN with a focus on coatings onto copper substrates;
• Contribute in the projects of SRF thin film coatings related to the upgrade and consolidation of existing facilities at CERN (LHC, HIE-ISOLDE);
• Coordinate the characterization of superconducting coatings by surface analysis, electron microscopy, X-ray diffraction and other relevant techniques;
• Coordinate the activity of substrate preparation, coating and RF testing at CERN;
• Manage the established collaborations for SRF thin films R&D activities with external institutes;
• Design and upgrade dedicated physical vapor deposition (PVD) systems according to the identified materials and objects to coat;
• Transfer and upgrade the existing coating facilities to the new SRF dedicated building to be accessible in 2029;
• Promote innovation to maintain the Organization knowledge at the state of the art in the domain of superconducting thin films.

Master's degree or equivalent relevant experience in the field of physics or material science (or equivalent) or a related field.

A PhD in the field of thin film coating would be an asset.
