Mechanical Engineer or Applied Physicist for Ultra-High Vacuum Technology (TE-VSC-BVO-2024-146-LD)

Company Description

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

Job Description

Introduction

Are you ready to work on one of the most advanced vacuum systems on the planet? With 130 km of cutting-edge vacuum vessels, CERN operates one of the largest and most complex vacuum systems ever built. If you're driven by the challenge of pushing the boundaries of science and technology, this is your chance to make a mark. Join the Vacuum, Surfaces, and Coatings Group and be part of something extraordinary!

The Vacuum, Surfaces, and Coatings (VSC) Group is at the forefront of CERN’s pioneering technological research, overseeing all high and ultra-high vacuum systems across the CERN accelerators. From design to operation, surface engineering to acceptance tests, we handle it all. The Beam Vacuum Operation section (BVO) ensures the flawless operation and continuous upgrade of the vacuum equipment critical to the Large Hadron Collider (LHC), the most powerful particle accelerator ever built. This includes the systems that enable hadron beams to circulate through superconducting magnets and detectors.

Functions

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

• Operate, maintain and consolidate complex and highly specialised ultra-high vacuum equipment, instruments and prototypes for particle accelerators.
• Model and design vacuum systems and predict their behaviour under different operating conditions. Built and test prototypes to validate designs and make necessary adjustments. Choose the appropriate materials and manufacturing process to ensure system reliability and performance.
• Analyse the performance of vacuum systems under operation conditions and diagnose failures to determine root causes and implement corrective actions.
• Test materials for compatibility with vacuum environments, particularly for outgassing rates and thermal properties.
• Lead and participate in activities aimed to install new or consolidated vacuum equipment in accelerators.
• Play an active role in multidisciplinary projects, requiring close collaboration with teams in charge of other accelerator systems and engineering fields.

Demonstrated experience in hands-on installation, commissioning and operation of ultra-high vacuum systems,

Experience:

Demonstrated experience in preparing scientific documentation and technical procedures for ultra-high vacuum systems,

Knowledge of surface treatments and thin-film coatings for ultra-high vacuum applications.

Technical competencies:

• Installation and commissioning of vacuum systems
• Knowledge and application of materials, surface and thermal treatments for UHV
• Knowledge and application of leak detection techniques and equipment
• Design and simulation of UHV systems

Behavioural competencies:

• Working in Teams:
  • Working well in groups and readily fitting into a team; participating fully and taking an active role in team activities,
• Communicating Effectively:
  • Providing others with timely information,
  • Ensuring that information, procedures and decisions are appropriately documented,
• Achieving Results:
  • Having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind,
• Solving Problems:
  • Identifying, defining and assessing problems, taking action to address the,
  • Finding the information needed to solve problems; making objective judgments based on all the facts available.

Language skills:

Spoken and written English: ability to draw-up technical specifications and/or scientific reports and to make oral presentations.

Ability to understand and speak, or willingness to learn and improve French.
