WebIon traps create a three-dimensional analogue of the quadrupole mass analyzer by virtue of their construction. Here, three electrodes with hyperbolic surfaces function to trap charged ions: two endcap electrodes and a central ring electrode. Because ions are subjected to electrical fields from three directions, not two, they do not move. WebJan 5, 2024 · To reach this ambitious goal, ATIQ brings together the leading groups in ion-trap research at the Leibniz Universität Hannover / PTB Braunschweig, at the Johannes Gutenberg University Mainz, and at the University of Siegen, as well as research institutions, and strong industry and technology partners. “We want to take the next big step together.
