The specific tasks within the project will be: designing mechanical components for the probe head, fabrication of the individual components with 3D printing ,establishing a test setup involving electrical signal acquisition and processing devices to measure the rotational speed. During the Master thesis, you will acquire hands-on experience on mechanical and electronics design as well as 3D printing. In addition, you will have opportunities to get exposure to a wide range of instruments and techniques. You will be integrated in the larger team of the Spin & Photon Applications (SPA-) Laboratory. Within this project, you will use the infrastructure existent at the Institute of Microstructure Technology (IMT), i.e., microfabrication facilities, RF testing equipment, and multiple state of the art NMR scanners. This is a complete project, offering the possibility to fabricate and test the devices, giving you the opportunity to co-author conference and/or journal publications.
