Joel Leser presented his bachelor's thesis on "High Frequency Control of Piezoelectric Oscillators". For this project, he designed, developed, and tested a coupler that combines signals of different frequencies and significantly different amplitudes — a technically demanding challenge. The designed coupler will in the end enable magnetic field ramps at speeds that were previously out of reach for our experiments. Congratulations, Joel, on a very tangible and impactful first contribution to the research lab!
