Evaluation and Analysis of Microwave Flex Resonators designed to induce the spin-flip in Positrons within the Antihydrogen atoms trapped at the ALPHA apparatus

The absence of antimatter, the counterpart to matter, represents one of the most profound mysteries in modern physics and is the subject of extensive research at CERN (the European Organization for Nuclear Research). A leading experiment in this field is ALPHA (Antihydrogen Laser Physics Apparatus), which aims to study the properties of antihydrogen, the antimatter equivalent of hydrogen. A significant achievement of the ALPHA experiment has been the observation of resonant quantum transitions in trapped antihydrogen. To take measurements further, a precise and accurate flexible microwave resonator is required to induce spin flips in the antiprotons within the antihydrogen atoms. As part of this effort, thirteen different microwave resonators were designed and fabricated. In this way, this project focuses on the design and implementation of tools to analyse and evaluate the performance of these resonators. Additionally, the project includes a thorough analysis and interpretation of the results, contributing to the refinement of the experimental techniques used to study antihydrogen.
