Ion Trap Experiment (IMAGE) University of Cologne Caption The CH5+ molecular ions were investigated in an ion trap setup such as this. The trap itself is the illuminated cylindrical cavity in the middle of the photo, in which some trap electrodes can be seen. In this trap, several thousand CH5+ ions were stored, cooled, and investigated by a laser. The obtained high-resolution spectra are shown in the inset, as well as a sketch of the CH5+ molecule in motion.
