Abstract
An ion trap comprises a ring electrode and opposite first and second endcap electrodes situated at opposite ends of the ring electrode. A waveform generator is configured to vary both frequency and amplitude of an AC waveform applied across the first and second endcap electrodes as a function of time, thereby exciting ions with a band of resonant secular frequencies substantially without exciting ions with adjacent secular frequencies.
