Job Description

Your responsibilities

Have you ever wanted to be involved in irradiation experiments for qualifying detector prototypes, materials and electronics to be installed in the High Luminosity LHC (HL-LHC), its experiments or future particle accelerator projects? IRRAD and GIF++ are our two irradiation facilities to qualify components and systems to be used in harsh radiation environments. If you relish a challenge, join the Detector Development section (DD) of the Detector Technology Group (DT) and realize your potential. Take part

The Detector Technology Group (DT) within the Experimental Physics Department (EP), responsible for providing expertise and services in various fields of detector technologies, is looking for a motivated Mechanical Technician to join our team. In this role, you will have the unique opportunity to work on the operation of the CERN detector test facilities IRRAD (CERN proton IRRADiation facility) and GIF++ (CERN Cs-137 Gamma Irradiation Facility) taking a critical role in providing electro/mechanical support to the CERN community in the field of radiation testing, qualification as well as dosimetry and radiation monitoring.

Specifically, you will:

  • Actively participate in the operation and maintenance of the IRRAD and GIF++ irradiation facilities equipment and setups, including the associated laboratory infrastructure.
  • Contribute to the design, manufacturing and testing of setups for detector irradiation tests, including preparation of mechanical drawings, electro/mechanical systems and interaction with commercial suppliers to fabricate equipment.
  • Support senior staff during experiments installation and tests execution, as well as in the reporting of results.
  • Support users at the two facilities throughout the whole process, from planning to execution, as well as contribute to the execution of the dosimetry measurements required for the follow-up of the irradiation experiments.
  • Technically support research and development for new particle beam measurement technologies and detectors (for intensity and/or profiling) designed for high-energy proton beams and gamma-rays environment.
  • Contribute to managing the EU-funded EURO-LABS Transnational Access program for the two EP-DT irradiation facilities.

Your profile

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.

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.
