## Abstract

Most of the matter in our universe is hidden from our view. We can’t see it directly, but we know it’s there because of the way it pulls on the things we can see, like stars and planets. One possible type of this invisible matter is called the axion. Scientists first suggested the existence of axions in the 1970s to help explain a major mystery in particle physics: why neutrons have a very small electric dipole moment. If we can find axions or similar particles, it could help answer some of the biggest questions in physics. In physics laboratories, axions might create new types of forces between atomic nuclei that can be measured at very small distances. The Axion Resonant InterAction DetectioN Experiment, known as ARIADNE, uses a technique called nuclear magnetic resonance to detect these forces. In this experiment, a mass is placed near a detector made of helium-3 atoms. This causes the detector’s magnetic properties to change, allowing scientists to see the axions moving between the mass and the helium-3. The ARIADNE project aims to complete the setup of the experiment and start collecting data. As part of this research, a team made up of postdoctoral researchers, graduate students, and undergraduate students will receive training in important areas like precision measurement, low-temperature physics, micro-fabrication, vacuum technology, and data analysis. This experience will help prepare them for future careers in science.
