Job Description
Your responsibilities
Are you a skilled applied physicist or material scientist who is passionate about developing, testing and applying new material treatment processes for large vacuum systems ? CERN, take part!
You will join the Vacuum Surface and Coatings group in the Technology Department, which is responsible for the fabrication, installation operation and maintenance of the vacuum systems in CERNs accelerator complex. As a member of a small team, you will be working on the development of a laser surface treatment designed for vacuum components which are facing directly the particle beam of the Large Hadron Collider (LHC). In the cold (cryogenic) parts of the LHC, the vacuum system includes copper pipes designed to reduce the thermal load induced by the particle beam. The laser surface treatment under development aims at mitigating the thermal load by reducing the effect of electron multiplication of the surface. This can be achieved by creating a roughness which lowers the secondary electron yield of the surface. Such a surface has never been inserted in LHC an preliminary tests are necessary before the treatment of several magnets.
As a physicist specialized in laser technology, you will we operate a unique setup for laser surface treatment of inner tube surface and you will producing a prototype vacuum chamber envisaged to be inserted in the vacuum system of the LHC in the winter break 2023-2024 to validate, in presence of the particle beam, the compatibility of the laser technology with requirements of safe machine operation.
As part of your activities, you will:
Identify areas for improvement of the experimental setup in collaboration with project partners and test themDefine the final treatment parameters via material analyses and parameter studiesIntegrate all optical, electronic and mechanical equipment into a functional solutionPerform and document the laser treatmentYour profile
Skills and/or knowledge
- Experience on operation of high power lasers as well as calibration and alignment of optical systems - Knowledge of principles and methods of surface and material analysis - Knowledge of basics principles of robotics and control systemsFluent in English, the ability to work in French would be an advantage.Eligibility criteria:

About us
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.
