As a Mechanical Technician in the Superconducting RF Cavity Technology Section (SRF) within the Radio Frequency Group (RF) of the Accelerator Systems Department (SY) at CERN, you will play a crucial role in assembling, testing, and maintaining superconducting cavities for CERN's particle accelerator complex. You will learn how to support the preparation of SRF cavities both inside and outside the cleanroom, ensure the mechanical integrity and quality of components used in sensitive cleanroom assemblies, and contribute to the efficient operation of cryomodule assembly processes.
Your responsibilities:
Under supervision and as part of a team, you will:
Take part in mechanical assemblies in both cleanroom and non-cleanroom environments, adhering to protocols and procedures.Qualify critical components, ensuring compliance with cleanliness standards.Contribute to the assembly of complex cryomodules, ensuring all mechanical components are properly integrated.Perform anti-dust cleaning with ultra-pure water at both low and high pressure on SRF cavities and related ultra-high vacuum components.Produce reports documenting cleanroom activitiesManage the stock of consumables, assist in the regular maintenance of cleanroom facilities and associated equipment.Your profile

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.
Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
