Applied Physicist for Penning Trap in Genf

You will contribute to improving the performance of a Penning trap used in the HIE-ISOLDE post-accelerator to accumulate, cool and bunch high-intensity radioactive ion beams prior to charge breeding and acceleration. The work includes mechanical design and modification of internal trap components, production follow-up and quality assurance, as well as assembly and functional testing. You will also perform simulations of non-neutral plasmas and participate in experimental studies with Paul traps. Working within a small, collaborative team, you will apply and expand expertise in ion-trapping physics through both theoretical and hands-on activities.
