Your responsibilities

You will join:

- The Accelerator Systems Department (SY), which is responsible for the beam-related technical systems of the CERN accelerators. The SY teams design, build and operate equipment systems in all CERN accelerators, and are engaged in ambitious forward-looking R&D programmes.
- The Sources, Targets and Interactions group (STI) that has the mandate to study the interactions of beam with matter, aiming to apply its know-how to particle generation and to particle interception. The skills involved and available in the group include Nuclear Physics and Engineering, Mechanical engineering, Material Science, Control systems and Electronic design, Photonics and Laser spectroscopy.
- The Lasers and Photocathodes section (LP) that is in charge of laser-based particle sources, in particular the RILIS (Resonance Ionization Laser Ion Source) of the ISOLDE radioactive ion beam laboratory and the photoinjectors of the Compact Linear Collider CLIC test facility. The section also contributes to the construction and operation of laser installation and laser beams for the AWAKE experiment.

In this position, you will:

- characterize, develop and optimize application-specific resonance ionisation laser ion sources for ISOLDE;
- develop and validate modelling methods;
- investigate design improvements for the enhancement of performance aspects such as ion survival, efficiency, ion capacity and selectivity.

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.
