Job Description
Your responsibilities
The Vacuum Surfaces and Coatings (VSC) Group within the Technology (TE) Department is responsible for the entire lifecycle of accelerator vacuum systems at CERN from development and design to installation operation and maintenance. We operate facilities for the measurement of vacuum performance and compatibilities of materials and surface technologies as well as for thin film coating surface finishing and vacuum-related physical and chemical characterization.
These activities are in-line with the needs of the FCC-ee study for which we need to lower the surface resistance of Nb thin films when used in radiofrequency regime.
As an Applied Physicist your main activities will consist of:
- Performing Nb thin films coatings onto various type of Cu based accelerating cavities (1.3GHz 400MHz 800MHz) by using the HiPIMS technique.
- Performing XRD quantitative data analysis.
- Studying the effect of different discharge gases onto the RF surface resistance of Nb using HiPIMS.
- Investigating the use of a dielectric barrier as a method for suppressing thermoelectric currents during SRF cavities cooldown.
- Commissioning and operating a moveable cathode sputtering system for 1.3GHz cavities.
- Commissioning operating and optimizing a sputtering system for 2-cells 400MHz cavities.
- Delivering 400MHz prototype cavities aligned with FCC-ee RF specifications.
Your profile
Skills:
- Demonstrated experience with using the HiPIMS coating technique.
- Experience with superconducting thin film elaboration on accelerating cavities.
- Experience with X-ray diffraction data analysis using Rietveld refinement.
- Experienced with Ultra High Vacuum systems.
- Experienced with assemblies in cleanroom environment.
- Spoken and written English or French with a commitment to learn the basics of the other language.
Eligibility criteria:
- You are a national of a CERN Member or Associate Member State.
- You have a professional background in Material Science Engineering Physics (or a related field) and have either:
- a Masters degree with 2 to 6 years of post-graduation professional experience;
- or a PhD with no more than 3 years of post-graduation professional experience.
- You have never had a CERN fellow or graduate contract before.
Additional Information :
Job closing date: 15.07.2025 at 23:59 CEST.
Contract duration: 24 months with a possible extension up to 36 months maximum.
Working hours: 40 hours per week
Target start date: 01-October-2025
This position involves:
- A valid driving licence.
- Stand-by duty when required by the needs of the Organization.
- Use of certain mobile work equipment or equipment used for lifting loads (lifting equipment bridge cranes aerial work platforms etc.) requiring a driving authorization.
Given the occupational health risks associated with this position the selected candidate must obtain medical clearance before a contract offer is confirmed.
Job reference: TE-VSC-SCCGRAP
Field of work: Applied Physics
What we offer
- A monthly stipend ranging between 6287 and 6911 Swiss Francs per month (net of tax).
- Coverage by CERNs comprehensive health scheme (for yourself your spouse and children) and membership of the CERN Pension Fund.
- Depending on your individual circumstances: installation grant; family child and infant allowances; payment of travel expenses at the beginning and end of contract.
- 30 days of paid leave per year.
- On-the-job and formal training at CERN as well as in-house language courses for English and/or French.
About us
At CERN the European Organization for Nuclear Research physicists and engineers are probing the fundamental structure of the universe. Using the worlds 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 .
