The CNRS LAPP (Laboratoire d'Annecy de Physique des Particules) institute is opening a 3 years fixed terms research engineer position.

In support of work package technical manager, and in collaboration with other actors of the project, the candidate's main mission will be to contribute to the ongoing developments concerning the vacuum tubes of the Einstein Telescope. Still at the preliminary stage, this project aims to assess the feasibility, performance and costs of various possible designs. In the mid-term (two years), chosen solution(s) will be launched in manufacturing to integrate the pilot sector of several tens of meters, which will be installed at CERN. This prototype aims to consolidate the cost and performance of this optimized design for the Einstein Telescope.


• Contribute to design and development of various vacuum tube designs.
• Contribute to finite element calculations to assess performances of the different concepts.
• Design and develop the associated mechanical assemblies: supports, production and installation tools
• Participate in progress and collaboration meetings (CERN, industrial partners)
• Identify potential industrial partners and contribute to cost assessment.

Attachment: Mechanical Service


• In-depth knowledge of the principles and methods of mechanical design
• In-depth knowledge of finite element calculation techniques: static buckling, dynamic, thermal.
• Ability to deal with the industrial environment.
• Proficiency in CATIA-V5 / 3D software experience and Ansys Workbench would be a plus
• Young graduates accepted, a first experience would be a plus
• Fluency in English reading, writing and speaking essential

Desired educational level: engineering degree
Desired work experience: 0 to 10 years

Work Context

LAPP is a combined CNRS and “Savoie Mont-Blanc” University unit. Close to 150 people are working at LAPP: researchers, professors, engineers and support staff, students and visiting scientists. The laboratory is very actively involved in several large international collaborations working on accelerators (ATLAS and LHCb on the LHC at CERN, BaBar at SLAC in California, OPERA in Gran Sasso) and astroparticle experiments (Virgo, AMS, H.E.S.S. and CTA). Involved in many R&D and construction programs for large research infrastructures, the laboratory's skills cover a large scope of domains involving innovative technologies in micro-electronics, complex mechanical structure design and optimization, grid computing and scientific software developments. The location of LAPP, 50 km from CERN, and the presence of the theory laboratory LAPTh in the same premises, make the LAPP campus a very attractive research place for scientists contributing to particle and astro-particle physics. LAPP hosts the MUST mid-range data storage and computing centre - widely open to distributed computing infrastructure supporting research and academic projects.

As part of the implementation of the vacuum tube demonstrator project for the “Einstein Telescope” gravitational wave detector project, the LAPP mechanical department wishes to strengthen its project team by recruiting a research engineer. The Einstein Telescope is the next major European research infrastructure dedicated to the observation of gravitational waves, currently in the preparation phase.

Constraints and risks

Some short trips have to be planned in France and abroad
