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 5):
The side-on injection Penning trap of  claim 2 , wherein the charged particle injection device comprises\n a third set of three trapezoidal electrodes printed outside of the first set of electrodes on the first PCB and a fourth set of three trapezoidal electrodes printed outside of the second set of electrodes on the second PCB,\n wherein the third set of electrodes and the fourth set of electrodes each include a central trapezoidal electrode with two diagonal sides of equal length and with a width that tapers toward the first set of electrodes or the second set of electrodes and two outer trapezoidal electrodes on either side of the central trapezoidal electrode that each have a diagonal side adjacent to a diagonal side of the central trapezoidal electrode and a horizontal side opposite the diagonal side, that each have a width that tapers away from the first set of electrodes or the second set of electrodes, and that together with the central trapezoidal electrode form a rectangular shape, \n wherein the three trapezoidal electrodes of the third set of electrodes and the fourth set of electrodes correspond in shape and size, and corresponding electrodes of the third set of electrodes and the fourth set of electrodes face each other across an axial gap between the third set of electrodes and the fourth set of electrodes, \n wherein the two outer trapezoidal electrodes of the third set of electrodes and the fourth set of electrodes are biased with a radio frequency (RF) voltage to apply a quadrupole electric field to the axial gap and the central trapezoidal electrodes of the third set of electrodes and the fourth set of electrodes are biased with a direct current (DC) voltage to minimize effects of the dielectric material of the first PCB and the second PCB, and \n wherein the charged particle injection device is mechanically shifted by printing the third set of electrodes on the first PCB shifted from the axis of the radial non-conducting path and printing the fourth set of electrodes on the second PCB shifted from the axis of the corresponding radial non-conducting path.
