| Popis: | Digital waveform technology allows the waveform frequency and duty cycle to be instantly changed. These sudden changes affect ion motion and hence ion energy. Mass spectrometrists can take advantage of these sudden changes to isolate or excite trapped ions. To understand these processes on the microsecond time scale, a theoretical treatment of ion motion during the first repetitions of the newly applied waveform is needed. Fortunately, the matrix solution to the Hill equation allows the observation of ion trajectories before, during, and after the waveform transition process. This study begins the investigation of the short time scale effects of changing waveforms on ion motion. |
