Junior Radiation Protection Physicist

Vor 4 Tagen


Geneva, Schweiz CERN Vollzeit

Your responsibilities

As a Radiation Protection Physicist, you will be part of the Occupational Health & Safety and Environmental Protection (HSE) Unit, specifically the Accelerators & Sites (AS) section of the HSE Radiation Protection (RP) Group. You will join a young and dynamic team, working on the future upgrade of the Large Hadron Collider (LHC), known as the High-Luminosity Large Hadron Collider (HL-LHC).

In the context of the LHC upgrade, several parts of the accelerator complex must be upgraded to meet the requirements of HL-LHC and support high-luminosity operation. Advanced planning of these activities, along with optimization from a radiological perspective, is strategically important for the organization, the project, and the protection of personnel and the environment. Indeed, more than 800 meters of accelerator components need to be dismantled and replaced with new beamline elements, and nearly 600 kilometers of cables will be removed and replaced. Additionally, the two beam dumps—components designed to safely absorb the LHC beams—will be replaced with new equipment specifically designed for the HL-LHC. Finally, radiological studies are required to finalize the design of several components for the new HL-LHC machine.

Your tasks will include:

- Performing Radiation Protection FLUKA Monte Carlo simulations relevant to the HL-LHC project.
- Assessing the induced activation in LHC and HL-LHC beamline elements using the ActiWiz code.
- Following up on the radiological characterization of the activated LHC cables, in preparation for their removal, using FLUKA simulations and measurements.
- Conducting radiological studies for the design of the new HL-LHC beam dump and providing support for the decommissioning of the current operational dumps.

Additionally, you will:

- Regularly report to your supervisor.
- Produce reports and technical notes and present your work at project meetings.
- Present relevant scientific results at conferences and/or in scientific publications.

- Strong interpersonal and communication skills.
- Fluency in English; willingness to learn French.

Eligibility criteria:

- You are a national of a CERN Member or Associate Member State.
- By the application deadline, you have a maximum of two years of professional experience since graduation in Physics or Energy/Nuclear Engineering (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
- You have never had a CERN fellow or graduate contract before.
- Applicants without University degree are not eligible.
- Applicants with a PhD are not eligible.

Job closing date: 12.12.2024 at 23:59 (midnight) CET.

- Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract.
- 30 days of paid leave per year.
- On-the-job and formal training at CERN as well as in-house language courses for English and/or French.

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.
