12474 IUPAC Gold Book - magnetron motion 10.1351/goldbook.12474 12474 current 1 Slow rotation of the center of cyclotron motion around the central axis of a Penning ion trap that results from a drift of the cyclotron centre along the electric equipotential lines perpendicular to the magnetic field direction. The characteristic frequency of this motion is called the magnetron frequency.
