Ion motion excitation
{"Image DocumentName": "Ion motion excitation", "Image ImageDescription": "Any of the three eigenmotions can be modified by using time-varying electric fields. Usually the ring electrode (or one of the correction electrodes between is radially split in order to create electric fields that have azimuthal and/or axial component. Using a time-varying dipolar electric field with a frequency of one of the eigenmodes will increase or decrease the radius of the corresponding motion. Motion excitation with quadrupole fields is another commonly used technique. With a quadrupole field one can couple two motions like cyclotron and magnetron motion with a quadrupole field having frequency \u03bd + +\u03bd \u2212 .With ion motion excitations, mass-over-charge ratio of trapped particles can be linked to frequency, which can be easily determined with high accuracy.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
