In a cold superconducting joint, a joint cup is provided. Lengths of superconducting filaments are placed in the joint cup. A superconducting material fills the joint cup in contact with the superconducting filaments and in thermal and mechanical contact with a pipe carrying a cryogen. The pipe extends into the joint cup and the superconducting material extends around the pipe within the joint cup.

Superconducting joints

An annular end piece for a cylindrical vacuum vessel, comprising a metal end piece (); an outer decorative shell () spaced away from a surface of the metal end piece; and a layer of solid foam filling the space between the metal end piece and the outer decorative shell.

Vacuum vessel for cooled equipment

A protection apparatus for a superconductive magnet unit has a support frame for location relative to a portion of the superconductive magnet unit. The support frame is arranged to carry a buffer for protecting the superconductive magnet unit from a shock load.

Protection apparatus, method of locating a superconductive magnet unit and superconductive magnet unit apparatus

In an arrangement with a basic field magnet and with a gradient coil of a magnetic resonance apparatus, the basic field magnet includes superconducting coils that are arranged in a reservoir with liquid helium for cooling. The helium reservoir is surrounded by a further reservoir, designated as an outer vacuum chamber. A vacuum exists between the outer vacuum chamber and the helium reservoir. A cryoshield is arranged between the outer vacuum chamber and the helium reservoir. The gradient coil is arranged in the inner chamber of the basic field magnet. The outer vacuum chamber has an additional coating with a high electrical conductivity.
