Trainee in optimization of a Single-Electron Accelerator

Your tasks

You will optimize a model of a superconducting radio-frequency accelerator for single electrons, with the goal of achieving the best possible temporal and spatial coherence. To this aim, you will use a code that allows to track the electron through the accelerating cavity and calculate the beam parameters. Since this tracking is time-consuming, you will use surrogate modeling and optimization algorithms. You will work with a diverse team of scientists, engineers and technicians in the electron beam instrumentation group.

Your profile

  • You are a student of physics, engineering, or computer science, and you are at least in your penultimate year of undergraduate study (minimum 4 semesters) 
  • You have strong programming skills in MATLAB, Python, or a similar high-level language 
  • Ideally, you are familiar with computational frameworks and libraries relevant to optimization and machine learning 
  • You have excellent analytical and problem-solving abilities, with a keen attention to detail 
  • You have not yet completed your Master’s thesis

We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration. 

The contract will be limited to 3 months.
