A segmented printed-circuit-board trap for macroscopic particles — •Joachim Zoll, Heather Partner, Alexander Kuhlicke, and Oliver Benson — AG Nanooptik, Institut für Physik, Humboldt-Universität zu Berlin, Newtonstraße 15, 12489 Berlin, Germany

In this presentation, a linear Paul trap for the investigation of levitating macroscopic particles such as diamonds with nitrogen-vacancy-defects [1] is introduced. The trap consists of two printed-circuit-boards (PCB), which are easy and fast to fabricate. For a rapid characterization of many different particles, the trap is separated in 12 segments, to establish loading, storing and subsequent analysis. Good optical access is ensured through a window in the side of the PCB. This is important for the detection of low optical signals. I will present a finite-element-simulation of the pseudo-potential for different particles, which have been stabilized in the PCB-trap. The stability of the trap was tested with microspheres (SiO2) and various diamonds under atmospheric pressure.
