Abstract:
Improvements to a side-on Penning trap include methods to stabilize ions in the trap. The ions are stabilized by injecting ions in the focusing region of the non-uniform DC fields produced by the pad electrodes of the trap. Ions are injected along an injection axis shifted from the central axis of a gap between a positively biased electrode pad and negatively biased electrode pad of the trap. Improvements also include methods to compensate for the Lorentz force that is produced when ions are injected into a side-on Penning trap. Electrodes of an ion injection device are DC biased so that the electrodes produce an electric field along the axis of the device that compensates for the Lorentz force. Finally, methods are provided to increase the m/z range of ions injected into a side-on Penning trap by pre-trapping ions just before injection of the ions into the trap.

Claim (Index 14):
A method for injecting charged particles in a focusing region of an electric field in a side-on injection Penning trap, comprising:\n applying a quadrupole electric field to a cylindrical gap between a first set of electrodes printed on a first printed circuit board (PCB) and a second set of electrodes that correspond in shape and size to the first set of electrodes printed on a second PCB using the first set of electrodes and second set of electrodes,\n wherein the first set of electrodes and the second set of electrodes each include a central disk electrode and one or more concentric segmented ring electrodes, the central disk electrode and the next adjacent concentric segmented ring electrode are separated by a circular non-conducting path and each concentric segmented ring electrode is separated by the next adjacent concentric segmented ring electrode by a circular non-conducting path, and each of the one or more concentric segmented ring electrodes is segmented by at least two radial non-conducting paths extending from the circular non-conducting path around the central disk electrode to the outer edge of the outermost segmented ring electrode, \n wherein the second PCB is placed in parallel with the first PCB so that the second set of electrodes and the first of electrodes are coaxial and so that each electrode and non-conducting path of the first set of electrodes faces a corresponding electrode and non-conducting path of the second set of electrodes, \n wherein the space between the first set of electrodes and the second set of electrodes is a cylindrical gap used to trap charged particles, and \n wherein the first set of electrodes and the second set of electrodes are biased to apply a quadrupole electric field to the cylindrical gap; \n applying a magnetic field to the cylindrical gap that is coaxial with the cylindrical gap using at least one permanent magnet that is placed coaxially with the first set of electrodes and the second set of electrodes but outside of the cylindrical gap,\n wherein the effects of the magnetic field and the quadrupole electric field combine to trap charged particles in the cylindrical gap; and \n injecting charged particles into the cylindrical gap in a direction perpendicular to the magnetic field and parallel to a radial non-conducting path of the first set of electrodes and a corresponding radial non-conducting path of the second set of electrodes using a charged particle injection device,\n wherein in injection mode, segments of the concentric segmented ring electrodes of the first set of electrodes on opposite sides of the radial non-conducting path are oppositely biased and segments of the concentric segmented ring electrodes of the second set of electrodes on opposite sides of the corresponding radial non-conducting path are correspondingly oppositely biased, producing an electric field in the cylindrical gap between the radial non-conducting path and the corresponding radial non-conducting path that has a focusing region and a defocusing region and \n wherein in injection mode, the charged particle injection device injects charged particles into the cylindrical gap along an axis of injection that is shifted from the axis of the radial non-conducting path and the axis of the corresponding radial non-conducting path towards segments of the concentric segmented ring electrodes of the first set of electrodes and towards segments of the corresponding concentric segmented ring electrodes of the second set of electrodes that are biased with the same polarity as the polarity of the charged particles so that the charged particles are injected in the focusing region.
