Applied Physicist

Company Description

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.

Job Description

Intra-beam scattering affects the beam quality of high brightness beams. This concerns the high intensity proton beams in the LHC, as well as the heavy ion beams all across the CERN accelerator chain. Tools for numerical integration (tracking) of macroparticle distributions have been developed at CERN to model and study this effect. In this Quest, you will:

• contribute to the consolidation of these tools and their integration into state of the art tracking codes
• benchmark simulation tools with experimental data from the LHC and the injectors
• study the impact of noise (power converter ripple, transverse damper, crab cavity noise) on transverse emittance growth in the LHC
• include this intra-beam scattering in accurate predictions of the luminosity evolution in the LHC

Qualifications

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State;
• You have a Master’s degree and between 2 and 6 years’ experience or PhD with up to 3 years of relevant experience in applied physics or other related field;
• You should have a working knowledge of English or French.

Skills and/or knowledge:

• You have knowledge in beam dynamics, optics design, beam instrumentation.
• You have experience in experimental techniques and analysis of data from beam measurements.
• You have knowledge of incoherent effects such as intra-beam scattering, and/or noise effects.

Additional Information

What we offer: 

• An employment contract of in principle 24 months, with a possible extension up to 36 months;
• On-the-job and formal training at CERN as well as in-house language courses for English and/or French;
• A monthly stipend ranging between 6050 and 6650 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.

 How to Apply:

You will need the following documents to complete your application:

• A CV;
• A scanned PDF of your most recent relevant qualification;
• We recommend to add two recent letters of recommendation, giving an overview of your academic and/or professional achievements. You can upload these letters at the time of application if you have them to hand. You will also be provided with a link as soon as you have submitted your application to forward to your referees to upload their letters confidentially.

The earliest expected start date for selected candidates is June 2023.
