Job Description

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.
We are on a Quest. A Journey into discovery like no other. Bring your expertise to our unique work and develop your knowledge and skills at pace. Join world-class subject matter experts on unique projects, in a Quest for greater knowledge and deeper understanding.

Diversity has been an integral part of CERN’s mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success

As an applied physicist, you will join the Linear and Non-Linear Optics Section (LNO) within the Accelerator and Beam Physics Group (ABP) under the Beams Department (BE), where you will be working on Magnetic and beam-based Modeling in CERN synchrotrons.
For the first time in 60 years of operation, it has been shown that we can develop magnetic models of the Proton Synchrotron (PS) main magnets to accurately predict changes in tune and chromaticity as energy increases.
This involved improving the magnetic model of the complex PS main magnets and refining the MAD-X optics models that estimate parameters based on OPERA predictions. It also required very careful setup of the optics measurements for comparison.

As an Applied Physicist, you will continue this work:

• Extend the existing model to cover the eddy currents and pole face windings as well as providing data for hysteresis modelling;
• Develop and Benchmark a magnetic and optics model for the LEIR bending dipole, using beam measurements;
• Depending on the progress made, improve models in the AD and PSB.
