Abstract Negative ions, probe particles of radius ∼ 10–20 Å, can be injected into helium, manipulated and detected. They can be trapped by quantized vortices and hence used as vortex detectors. We show that by observing the change of the ion current caused by rotation of helium one can learn about the presence and dynamics of vortices even at very low temperatures.
