Rendering of the stack of five identical cylindrical Penning traps of the PENTATRAP experiment. Traps 2 and 3, with labels marked in red, are used as measurement traps and are equipped with a detection system. Shuttling the ions from Position 1 into Position 2 effectively swaps the ion species in traps 2 and 3, resulting in the alternating data structure as shown in b . Traps 1 and 4 are used as storage traps, while trap 5 is not used in this measurement.
