Abstract: Improvements to a side-on Penning trap include a feedback system for stabilizing the magnetic field. This system includes a magnetic sensor that measures the magnetic field and a solenoid coil that in response to the magnetic field measurements increases or decreases the overall magnetic field. Improvements also include a number of different configurations of the two sets of PCB electrodes used to produce the quadrupole electric field. Dimensions of the PCB electrodes are optimized, an equipotential surface electrode is added, and additional ring electrodes are added to produce a purer quadrupole field. A central disk electrode is segmented to direct charged particles to the trap center to make the trap useful for applications other than mass spectrometry. Finally, outer ring electrodes are segmented to increase the path of charged particles, thereby increasing sensitivity.

Abstract: A method is provided for processing ions in a multipole ion trap, comprising generating RF radial confinement fields within a first and second multipole rod set positioned in tandem, a ratio of q value exhibited by the second rod set relative to the first rod set being greater than one for any m/z, said RF axial confinement fields within the first and second rod sets interacting in an interaction region between the first and second rod sets so as to produce a fringing field; transmitting ions through said first rod set towards said second rod set; and increasing the radial oscillation amplitude of at least a portion of the ions within said first rod set such that at least a portion of said ions having an increased radial oscillation amplitude are repulsed by said fringing field.
