ABRIDGED MULTIPOLE STRUCTURE FOR THE TRANSPORT, SELECTION AND TRAPPING OF IONS IN A VACUUM SYSTEM |
摘要 |
An abridged multipole structure for the transport and selection of ions along a central axis in a vacuum system is constructed from a plurality of rectilinear electrode structures, each having a substantially planar face with a first dimension and a second dimension perpendicular to the first dimension. When a voltage is applied across the second dimension, an electrical potential is produced at the planar face whose amplitude is a linear function of position along the second dimension. Two electrode structures can be arranged parallel to each other with the first dimension extending along the central axis or more electrodes structures can be arranged to form multipole structures with various polygonal cross sections. Additional embodiments can act as linear ion traps or Paul ion traps. |
