We have observed rapid ion loss from a Penning trap at certain operating conditions. Here the ratio of the cyclotron or axial oscillation frequency is an integer multiple of the “metastable" magnetron frequency. Higher-order contributions to the ideal quadrupole trapping potential causes energy transfer into the magnetron motion, whose orbit increases. This effect is analogous to the stop bands observed in accelerators and storage rings
