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 Photoemission 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 at SPS and the RILIS installation (Resonance Ionization Laser Ion Source) of the ISOLDE radioactive ion beam laboratory
This exciting opportunity is at the intersection of nanophotonics, material science, quantum electronics and accelerator physics with a view on relevant medical applications.
The Photoemission laboratory is CERNs photocathode factory for lepton accelerators used for fundamental and applied research spanning many disciplines from particle physics to medical applications. You will contribute to the developments being carried out in the Photoemission Lab for photocathodes and electron sources for FLASH therapy within the DEFT collaboration. The results of this project will have a positive impact for future projects at CERN (FCC, LHeC, etc) and beyond, such as for FLASH radiation therapy, FEL development and others.
You will:
Carry out the experimental work related to novel photoemissive technology using plasmonics, as well as supporting the design and integration of the DEFT photoinjector based on existing cesium telluride cathodes; Investigate such surface-plasmon assisted photoemission with a view on simplifying the photocathode production at CERN while extending the lifetime of existing photo-injectors;Your profile
Skills and/or knowledge
Experience with Electron beam production, manipulation and detection; Knowledge of Laser-matter interactions, Ultrafast laser technologies, Laser beam transport, manipulation and monitoring;Knowledge of Photoemission modelling; 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.Job closing date: 25.02.2024 at 23:59h (midnight) CET.
Job reference: SY-STI-LP-2024-14-GRAP

A monthly stipend ranging between 6194 and 6808 Swiss Francs per month (net of tax).Coverage by CERN's comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.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.
