**Job Description** Your responsibilities**

You will be part of:

- The Beams department, responsible for the beam generation, acceleration, diagnostics, controls and performance optimization for the LHC and its injector accelerators.
- The Accelerator and Beam Physics Group, which is responsible for studying and understanding the beam dynamics over the complete CERN Accelerator Complex through theoretical, simulation and experimental studies. The group provides input and support for machine operations, devising settings and scenarios to optimize the machine performance. It is also responsible for working out concepts and ideas for future accelerators.

In this position, you will lead the project of characterisation the Radio Frequency Quadrupole (RFQ) for carbon ion acceleration.

Specifically, you will:

- Perform the beam measurements on the RFQ at high frequency (750MHz) that is the pre-injector for a linac-based Carbon Ion Facility;
- Characterise the proton and carbon source in preparation of the RFQ commissioning;
- If time permits, study the implication on the folded linac layout of the measurement findings.

**Your profile**

Skills and/or knowledge
- Experience with beam measurements;
- Knowledge of the Radio Frequency Quadrupoles (at high frequency);
- Fluent in English, the ability to work in French would be an advantage.

Eligibility criteria:

- You are a national of a CERN Member or Associate Member State.
- You have a professional background in Applied Physics (or a related field) and have either:

- a **Master's degree with 2 to 6 years** of post-graduation professional experience;
- or a **PhD with no more than 3 years** of post-graduation professional experience.
- You have never had a CERN fellow or graduate contract before.
