Internship Experience at HYQU Laboratory, ETH Zürich - Summer 2022

Overview

During the summer following my first year at university, I had the opportunity to intern at the Hybrid Quantum systems group (HYQU) at ETH Zürich. This experience was pivotal in applying my theoretical knowledge in physics to practical challenges in the field of experimental physics.

Project Focus

My primary responsibility was to design and implement a stabilization system to suppress vibrations in the Cryostat Fabry-Perot interferometer experiment. The goal was to enhance the accuracy and reliability of the experimental setup.

Design and Development

• Differential Equations: I utilized my understanding of physics to derive a system of differential equations, focusing on amplitude attenuation in various systems. This theoretical framework was crucial for developing a viable solution.
  • Differential Equations for Natural Frequencies
• Modeling in COMSOL Multiphysics: To validate my calculations and theoretical models, I employed COMSOL Multiphysics software. This step was instrumental in refining the models and ensuring their practical applicability.
• Optimal System Design: The best model incorporated a combination of pendulums, springs, and eddy current dampers. This design was a result of extensive research and iterations.

Additional Responsibilities

• Physical Calculations: I conducted various physical calculations, including heat dispersion analysis from the superconductivity of the metal and the eddy current damper. These calculations were vital in understanding the thermal dynamics of the system.
• Magnetic Field Derivation: Deriving the approximate magnetic field from the magnet system was another critical aspect of my role, ensuring the system’s overall effectiveness.
