Job Description

Your responsibilities

Are you a highly motivated Mechanical, Aerospace or Nuclear engineer eager to take on exciting challenges? Do you have a solid technical background, experience in mechanical design? If so, we invite you to take part and join our dynamic team responsible for beam intercepting devices (BIDs) and radiation absorbers for FCCee.

The successful candidate will be responsible for the analysis and design of various beam intercepting devices for the FCCee study, including collaboration with P3 on the positron source, as well as work on collimators, MDI masks, radiation absorbers, lepton and beamstrahlung dumps, depending on the project priorities. The activity will also include development of the radiation absorbers for the FCCee main dipole system.

This role involves defining and analysing complex numerical models to assess the performance of these devices under thermo-mechanical forces, including dynamic effects. The candidate will utilise Implicit and Explicit Finite Element solvers, such as LS-Dyna and ANSYS, to conduct these analyses. Additionally, CATIA will be used for basic 3D modeling and integration studies of these components.

The project encompasses both simulation and practical work, including prototyping and testing activities aimed at developing and optimizing mechanical components, such as leak-tight connections (flanges, gaskets) and cooling systems. Depending on the candidate, the role will also involve conducting material characterization studies and exploring manufacturing techniques in collaboration with internal and external partners.

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.
