Rationale:
Linear quadrupole traps are employed in a wide range of applications. Here a linear quadrupole superimposed by a static transverse magnetic field in the x or y direction is considered. The magnetic field effect on the stability regions and performance of a linear quadrupole is surveyed.
Methods:
The equations of motion of particles in the trap with a static transverse magnetic field are calculated analytically. Subsequently, an applied magnetic field changes equations and stability parameters. The stability diagrams of a linear quadrupole trap with and without a static transverse magnetic field are compared.
Results:
A static transverse magnetic field applied to a linear quadrupole trap reshapes stability regions causing their area and position to change.
Conclusions:
Stability region reshapes caused by a static transverse magnetic field applied to a linear quadrupole trap are calculated analytically.

Magnetic Field due to Moving Charges
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
