Job Summary

Introduction

Join CERNs mission to advance accelerator technology. As an Engineer in the Superconducting Radio-Frequency Section you will design and develop key RF components for the new 400 MHz Demonstrator Cryomodule contributing to innovations that will drive the future of particle physics.

You will join the Accelerator Systems Department (SY) which is responsible for the beam-related technical systems of the CERN accelerators. The SY teams design build and operate equipment systems in all CERN accelerators and are engaged in ambitious forward-looking R&D programmes.

You will join the SC RF Cavity Technology Section of the Radiofrequency Group. You will participate in the development of RF power components and in particular the fundamental RF power couplers and HOM RF power extraction couplers which are highly sophisticated and critical components in the RF power transmission to accelerator SRF cavities.

Functions

You will join a multidisciplinary team developing advanced accelerator technologies for CERNs future program. Your work will focus on the design and development of key RF components Fundamental Power Couplers (FPC) and High Order Mode (HOM) extraction couplersfor the new 400 MHz Demonstrator Cryomodule (DEMO).

More specifically you will:

Take a significant part in the mechanical design of FPCs and HOM couplers including material selection and manufacturing technologies.
Perform coupled RF thermal and mechanical simulations across all operating conditions from room temperature to cryogenic (<4.5 K) optimising designs for efficiency and reliability.
Contribute to the design construction and operation of test stations for RF conditioning and high-power qualification.
Oversee the production and assembly of prototypes including preparation of specifications cleanroom procedures quality control and documentation.
Support cryogenic qualification testing on single cavities and full assemblies.
Collaborate across internal and external teams reporting progress and presenting results in workshops and conferences.

Qualifications :

Masters degree or PhD or equivalent relevant experience in the field of electrical or mechanical engineering or a related field.

Experience:

Demonstrated experience in mechanical and electrical engineering aspects of RF equipment applied to scientific instruments.
Demonstrated experience with electromagnetic simulation tools for evaluating RF fields power dissipation and multipacting effects in addition to mechanical and thermal finite element computations and computer-aided design software.
Demonstrated experience in coordinating multidisciplinary projects for scientific instruments covering the full lifecycle from conceptual and electromagnetic design through mechanical integration prototyping RF testing and qualification.
Experience in preparing technical specification technical reports and publishing paper in international conferences.

Technical competencies:

Knowledge and application of RF techniques: incl. electrical engineering techniques for the design testing and optimisation of superconducting RF systems.
Design and analysis of mechanical structures.
Knowledge and application of cryogenic heat transfer and insulation techniques.
Design and modelling of RF accelerating structures.
Knowledge and application of clean-room techniques.

Behavioural competencies:

Demonstrating Accountability: taking responsibility for own actions and decisions.
Learning and Sharing Knowledge: thinking out of the box and proposing fresh ideas insights and methodologies.
Managing Self: taking initiative beyond regular tasks and making things happen.
Working in Teams: understanding when teamwork is required to achieve the best results; including others accordingly and sharing information.
Demonstrating Flexibility: adapting quickly and resourcefully to shifting priorities and requirements.

Language skills:

Spoken and written English or French with a commitment to learn the other language.
