Superconducting radio frequency (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra-low electrical resistivity of a superconducting material allows an RF resonator to obtain an extremely high quality factor , Q .
Beginning in the 1960s, scientists at Stanford and elsewhere began to explore the use of superconducting radio frequency cavities for particle acceleration. [13] Superconducting cavities made of niobium alloys allow for much more efficient acceleration, as a substantially higher fraction of the input power could be applied to the beam rather ...
A cryomodule section of an accelerator is composed of superconducting ... An example of niobium-based 1.3 GHz nine-cell superconducting radio frequency to be put ...
Modern superconducting radio frequency, multicell linear accelerator component. In a linear particle accelerator (linac), particles are accelerated in a straight line with a target of interest at one end. They are often used to provide an initial low-energy kick to particles before they are injected into circular accelerators.

The cavities serve as resonators (tank circuits) to determine the frequency of the oscillators. A microwave cavity or radio frequency cavity (RF cavity) is a special type of resonator, consisting of a closed (or largely closed) metal structure that confines electromagnetic fields in the microwave or RF region of the spectrum.
Thin coatings can be used in superconducting radio frequency cavities to minimize energy loss and reduce the inefficiency of liquid helium cooled niobium cavities. Because of the low cost of its constituent elements, MgB 2 has promise for use in superconducting low to medium field magnets, electric motors and generators, fault current limiters ...
