Introduction

Are you looking for unprecedented challenges in the world’s largest and most amazing scientific instrument? Do you have experience in carrying out studies based on low-temperature physics? Then join CERN central cryogenic laboratory. Take Part!

You will join the Cryogenics Group, and the Cryolab & Instrumentation (CI) Section, that is responsible for the CERN central cryogenic laboratory. This lab is a research facility for systems working in a temperature range down to 50 mK, equipped with about ten test stands. The research program is based on demands specified by the CERN community and is varying from short duration experiments (several days) up to subjects covered by complete PhD programs. The diversity of people working in the laboratory, from CERN employees to students, makes it a lively environment and an attractive place to work.

Functions

As a thermodynamic engineer/applied physicist in the Cryolab & Instrumentation (CI) section, you will be in direct contact with the users of the laboratory. In collaboration with them you will study the physical properties they are interested in by analysing low-temperature thermal(-hydraulic) data obtained either from dedicated experiments performed in the laboratory, from large scale components test or from accelerator operation data.

The design/fabrication or modification of the laboratory test stands shall mostly be done in collaboration with the Cryolab colleagues, while information on large-scale components tests and accelerator operation shall be harvested in collaboration with sections from within as well as external to the group. Every project has to be documented, and the results to be presented to the users. The guiding of technical students, PhD students or fellows participating to your studies, will be part of your responsibility.

The modelling and numerical thermo-hydraulic simulations for superconducting devices used in CERN facilities such accelerators and detectors

Your functions will include:

• Conceive and perform low-temperature experiments.
• Analyze low-temperature thermal (-hydraulic) data ranging from dedicated lab-scale experiments to data from large-scale accelerator operation and component tests.
• Act as an expert user and developer of relevant analysis tools and numerical methods for simulation of observed thermo (-hydraulic) phenomena. This comprehends both commercial as well as in-house software tools.
• Develop models to guide the conception of future accelerator components, specifically but non-exclusively at the interface between cryogenics and superconducting magnet design.
• Active exchange with various stakeholders from within the TE Department groups and beyond if necessary.
• Represent the Organization at conferences, workshops, or in other research laboratories and institutions.

The candidate shall evolve to propose research and development projects and become subsequently responsible for the supervision of technical and academic collaborators.

Master's degree or PhD or equivalent relevant experience in applied physics, thermodynamics, mechanical engineering or a related field.
