Design and Implementation of a Blade-Type Linear Paul Trap (2504.15368v1)

Abstract: In this work, we present the design, implementation, and construction of a linear Paul trap in a blade configuration. The trap was optimized to minimize micromotion and enable the formation of linear ion chains comprising tens of ions. We use ytterbium atoms, and in particular, we describe the trapping and cooling of the isotopes $^{174} \mathrm{Yb}^+$ and $^{171} \mathrm{Yb}^+$, starting from an isotope-selective ionization process based on laser frequency stabilization and optimization of fluorescence for each isotope. The electronic control system-including magnetic field generation, laser delivery, and microwave driving-was fully implemented and is described in detail. The system supports pulsed operation, and we performed Rabi oscillations of the hyperfine states in the $^2 \mathrm{S}_{1/2}$ level, demonstrating coherent spectroscopy. These capabilities are fundamental tools for the experiments we aim to pursue, including the use of structured light beams, quantum simulation protocols, and the generation of non-classical motional states.
