[11] The linear form of the trap can be used as a selective mass filter, or as an actual trap by creating a potential well for the ions along the axis of the electrodes. Ions in a quadrupole field experience restoring forces that drive them back toward the center of the trap. A DIT is driven by digital signals, typically rectangular waveforms[22][23] that are generated by switching rapidly between discrete voltage levels. Sketch the electric field lines around two opposite charges, with the magnitude of the negative charge being smaller than the magnitude of the positive charge. 1 This is how much electric field the positive charge creates in the x direction.

In the two-dimension case (a so-called "linear RF trap"), confinement in the third direction is provided by static electric fields. To achieve this objective, a uniform magnetic field is added in the axial direction of the quadrupole ion trap. 2 [4] There are two main classes of traps, depending on whether the oscillating field provides confinement in three or two dimensions. Due to the air currents, ions, and water drops on ice particles in a thunderstorm, positive and negative charges are separated.

Supposing that the semiconductor initially is charge neutral, with the charge due to holes exactly balanced by the negative charge due to acceptor doping impurities. A pure quadrupole is created from hyperbolic electrodes, though cylindrical electrodes are often used for ease of fabrication. 911), and the negative charges are dumped into the ground in lightning strokes. [21] One of the main bottlenecks of a quadrupole ion trap is that it can confine only single-charged species or multiple species with similar masses. The boundaries of the shaded regions in the figure are the boundaries of stability in the two directions (also known as boundaries of bands). It indicates two different directions of the electric field lines which is impossible. This constraint is additionally present in the machining requirements of the 3D trap).[13].
