Engineering studies for Materials and Equipment under extreme conditions: In the context of beam intercepting devices, like for instance beam dumps, high power targets and collimators, thermo-mechanical studies using ANSYS and AUTODYN will be needed to validate existing equipment for future beam parameters. Development of objects for the LHC and Linac4 collimators and dumps as well as studies for machine upgrades and future programs. The candidate will integrate modifications to existing design or create a complete new concept (time depending). Aspects as heat loads and thermal behaviour, mechanical stresses, shock waves and impact, impedance issues and vacuum problems have to be combined into a robust design for the upgrade of the devices, keeping in mind radio protection issues. A close collaboration with the design office, the FLUKA team and Radio Protection is completing the tasks for this position. A special scope for this position is the aspect of an efficient cooling system. New techniques as heat pipes or cryogenic gas cooling might be considered and their impact on the mechanical design has to be evaluated. The construction of a demonstrator is foreseen at a later stage.
Special Requirements
University degree in mechanical engineering. Knowledge of analytical and numerical tools applicable to mechanical design, in particular in the fields of structural, thermal and dynamic analysis of machines and structures. Previous experience using a finite element analysis code, such as ANSYS, would be an asset.
Training Value
The trainee will gain experience with materials (graphite, tungsten, etc.) under particle impact with high energy densities and has the possibility to follow the full life cycle of the product from specification to commissioning. Some R&D on different cooling concepts
