Radio Frequency Quadrupole (RFQ)
... In RFQ the electrodes in the form of ‘rods’ or ‘vanes’ are placed in cavity resonators to prevent the RF fields from radiating. The issues related to the electrodynamics are distinct from those associated with the beam dynamics. The beam dynamics is confined to a region of small radius near axis as ...

... The densities of states at these regions primarily consist of Tc-5s, Tc-4d, and P-3p states. From Figure 2b, we can see that the bonding peaks ranged from −20 to −13 eV and the bonding peaks between 1 and 20 eV are mainly dominated by the P-3p state. The peaks of the bonding ranged from −13 to −6 eV ...

Dielectric
A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction. This creates an internal electric field that reduces the overall field within the dielectric itself. If a dielectric is composed of weakly bonded molecules, those molecules not only become polarized, but also reorient so that their symmetry axes align to the field.The study of dielectric properties concerns storage and dissipation of electric and magnetic energy in materials. Dielectrics are important for explaining various phenomena in electronics, optics, and solid-state physics.
