Over the last quarter of this century, revolutionary advances have been made both in kind
and in precision in the application of particle traps to the study of thephysics of charged …

A pulsed beam of ground state OH radicals is slowed down using a Stark decelerator and is
subsequently loaded into an electrostatic trap. Characterization of the molecular beam …

The theory of the computer calculation of the stability of ion motion in periodic quadrupole
fields is considered. A matrix approach for the numerical solution of the Hill equation and …

We demonstrate trapping of electrons in a millimeter-sized quadrupole Paul trap driven at
1.6 GHz in a room-temperature ultrahigh vacuum setup. Cold electrons are introduced into …

Using a new type of ion trap, we demonstrate that the length of a packet of charged particles
oscillating between two electrostatic mirrors will remain constant under special conditions …

We have detected excess micromotion of trapped ions by modulating the trapping voltage.
This radio-frequency (rf) modulation induces parametric resonance and excites secular …

The concept of phase stability in a Stark decelerator ensures that polar molecules can be
accelerated, guided, or decelerated without loss; molecules within a certain position and …

The motion of an ion bunch trapped between two electrostatic mirrors in an ion-trap
resonator is analyzed both experimentally and via numerical simulations. It is found that …

We study a method for mass-selective removal of ions from a Paul trap by parametric
excitation. This can be achieved by applying an oscillating electric quadrupole field at twice …

Modeling of ion motion and experimental investigations of ion excitation in a linear
quadrupole trap with a 4% added octopole field are described. The results are compared …
