The endcap trap, proposed by Schrama et al. [22], is a different geometric variant of a conventional quadrupole Paul trap and is a non-linear trap. Fig. 1 shows a model of the endcap trap used at NPL for atomic clocks and frequency standards experiments with 88Sr+ [17] and Yb+ [23].

Ion traps (March, ), also referred to as quadrupole ion traps, trap and store ions in an orbital motion within the ion trap and eject ions for detection. Storage is performed by collecting ions in a potential energy well, and ejection provides energy for ions to escape the potential energy well.

An ion trap, which was originally developed to cool down high-energy particles, [50][51] [52] [53] is now used in MS. 2,4,51,54,55) Various kinds of ion traps have been developed to hold, separate.

The key element of the mass spectrometer is a novel high ion capacity ion trap, combined in tandem configuration with a quadrupole collision cell and a quadrupole mass analyzer (i.e.

A theoretical method was proposed in this work to study space charge effects in quadrupole ion traps, including ion trapping, ion motion frequency shift, and nonlinear effects on ion trajectories. The spatial distributions of ion clouds within quadrupole ion traps were first modeled for both 3D and linear ion traps.
