At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. They use the world's largest and most complex scientific instruments to study the basic constituents of matter, the fundamental particles. The particles are made to collide together at close to the speed of light. The process gives the physicists clues about how the particles interact, and provides insights into the fundamental laws of nature.
Accelerator Physicist Job Description
Are you interested in working in the largest accelerator complex in the world?
Would you like to work at powerful synchrotrons in the injector chain of the Large Hadron Collider (LHC)?
Come and work alongside top scientists and engineers to exploit and upgrade CERN's accelorators. We are looking for an Accelerator Physicist for Radio Frequency (RF) Operation and Beam Studies to help operate the RF systems of the Super Proton Synchrotron (SPS) accelerator and to play a key role in improving beam and RF system performance of the SPS, its injectors and the LHC. This could be the next exciting challenge in your career… take part!
You will join:
- The Beams Department (BE), which hosts the Groups responsible for beam generation, acceleration, diagnostics, controls and performance optimisation. (http://beams.web.cern.ch/)
- The Radio-Frequency (BE-RF) Group (https://be-dep-rf.web.cern.ch/) of the BE Department, responsible for the operation of all RF systems to accelerate and control the particle beams in all CERN synchrotrons and linear accelerators, including projects for future accelerators and upgrades to the existing installations.
- The Beams and RF Studies (BE-RF-BR) Section within the RF Group takes care of the interactions of various beams (protons, anti-protons and heavy ions) with RF systems and their environment in all CERN synchrotrons. The BR Section is strongly involved in performance improvements and upgrades of existing accelerators as well as in the design of RF systems for present and future CERN accelerators. (https://be-dep-rf.web.cern.ch/content/br-beams-rf-studies)
As Accelerator Physicist for Radio Frequency Operation and Beam Studies in the BR Section, you will be part of the team running CERN's SPS accelerator, its injector (PS) and the LHC.
In particular, you will contribute to the operation of the RF beam control and feedback systems. A large part of your work on existing synchrotrons will be the study of performance limitations related to the RF systems and longitudinal beam dynamics (beam loading, stability, RF manipulations and others) and the means to push to higher beam intensities after the upgrades performed during the current long shutdown (LS2). These studies will consist of participation in beam measurements during beam commissioning and Machine Development (MD) sessions, followed by data analysis as well as analytical calculations and numerical simulations. This work will also involve further development of the existing longitudinal beam observation system, the follow-up of RF upgrades, as well as contributions to CERN projects, notably High Luminosity (HL)-LHC and the Future Circular Collider (FCC).
To summarise, your main activity will be to participate in the beam commissioning of the SPS towards HL-LHC intensity and in the operational issues related to the RF beam control system. Additionally, you will participate in beam studies and propose improvements.
After an initial learning period, you will:
- Set-up operational beams as well as beams with special parameters for various MD studies.
- Participate in beam commissioning (up to High-Luminosity LHC intensities) after the long shutdown 2 (LS2).
- Perform theoretical studies to analyse the longitudinal beam behaviour in the SPS and LHC.
- Suggest possible improvements to the RF systems and measures to increase beam quality and stability.
- Participate in MDs, notably related to the intensity increase of the LHC beams.
- Maintain longitudinal beam observation systems; suggest and implement improvements.
- Contribute to the upgrade of the RF beam control and feedback systems.
- Work closely with accelerator physicists, operations teams, RF power and hardware engineers to achieve the aforementioned tasks.
- Participate in the standby service for the low-level RF systems in SPS and LHC.
This vacancy will be filled as soon as possible and applications should normally reach us no later than 19/09/2019
Contract type: limited duration contract (5 years).
These functions require:
- Participation in a regular stand-by duty, including nights, Sundays and official holidays.
- Work in radiation areas.
- Interventions in underground installations.
- A valid driving licence.
Job grade: 6-7
