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 15):
A side-on injection Penning trap that includes a charged particle injection device that is biased to compensate for a Lorentz force experienced by charged particles flowing through the charged particle injection device, comprising:\n a first printed circuit board (PCB) on which is printed a first set of two or more concentric circular or semi-circular electrodes; a second PCB on which is printed a second set of two or more concentric circular or semi-circular electrodes that correspond in shape and size to the first set of electrodes, wherein the second PCB is placed in parallel with the first PCB so that the second set of electrodes faces and is coaxial with the first set of electrodes, 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 wherein the first set of electrodes and the second set of electrodes apply a quadrupole electric field to the cylindrical gap; 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 that applies a magnetic field to the cylindrical gap that is coaxial with the cylindrical gap, wherein the effects of the first magnetic field and the quadrupole electric field combine to trap charged particles in the cylindrical gap; and a charged particle injection device configured to inject charged particles into the cylindrical gap in a direction perpendicular to the magnetic field and biased to apply an electric field to the flow of charged particles in the charged particle injection device that compensates for a Lorentz force applied to the flow of charged particles in the charged particle injection device by the magnetic field outside of the cylindrical gap.
