Cryomodule

simplified sketch of a SRF cavity in a helium bath, with RF coupling and a passing particle beam.

A cryomodule is a section of a modern particle accelerator composed of superconducting RF (SRF) acceleration cavities, and needs very low operating temperatures (of around 2 Kelvin). The cryomodule is a complex, state-of-the-art supercooled component in which particle beams are accelerated for scientific research. The niobium cavities are cooled with liquid helium.

A cryomodule section of an accelerator is composed of normal conducting and superconducting cavities that accelerate the beam, also including a magnetic lattice that provides focusing and steering.

Design considerations

SRF cavities tend to be thin-walled structures immersed in a bath of liquid helium having temperatures of 1.6 K to 4.5 K. Careful engineering is required to insulate the helium bath from the room-temperature external environment. This is accomplished by:
