Applied Physicist TE-VSC-VSMGRAP

Your responsibilities

Are you an Applied Physicist with a deep interest in materials and their properties as applied to particle accelerators 

We invite you to take on a pivotal role in investigating the electrodynamic impedance of materials and its influence on the design and performance of particle accelerator components. This includes beamfacing surfaces which are integral to the accelerator vacuum system and its various parts. 

In this project you will engage in a wide range of activities including the study of surface roughness electrical conductivity and superconductivity. Collaborating with leading experts from different CERN Departments you will develop innovative tools to evaluate the electrodynamic properties of materials crucial for current and future CERN accelerators. 

This initiative is part of a core study within CERNs Technology (TE) Department specifically the Vacuum
Surfaces and Coatings (VSC) Group. Here advanced thin film coatings and surface treatments are developed for beamfacing surfaces of vacuum chambers and other components. These innovations aim to manage vacuum properties and secondary electron yield. As a key team member you will assess the impact on surface impedance by developing coaxial and dielectric resonators operating at cryogenic temperatures and multiple frequencies. This work will culminate in defining the optimal coating properties for each application. 

A significant part of your role will involve running simulation codes to design test equipment and model accelerator components. You will validate these simulations through experimental measurements. Additionally you will participate in projects focused on developing and evaluating superconducting thin film coatings further enhancing our capabilities to test thin film samples.

At CERN the European Organization for Nuclear Research physicists and engineers are probing the fundamental structure of the universe. Using the worlds 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 .
