Abstract
An electromagnet assembly has an inner magnet, an outer magnet, arranged around the inner magnet with an annular region extending between the inner magnet and the outer magnet, and a number of support elements extending through the annular region and dividing the annular region into a number of annular segments. The support elements are distributed in the annular region so as to form a small annular segment and a large annular segment.
Claims12
An electromagnet assembly for generating a strong magnetic field under superconducting conditions, comprising:
- an inner magnet;
- an outer magnet around the inner magnet, with an annular region extending between the inner magnet and the outer magnet;
- a plurality of support elements extending through the annular region and dividing the annular region into a plurality of annular segments;
- and
- said support elements being distributed in the annular region so as to form a first annular segment and a second annular segment, with the first annular segment being smaller than the second annular segment,
- wherein the outer magnet comprises:
- a first coil;
- a second coil spaced apart from the first coil;
- the first coil defining a first annular region;
- the second coil defining a second annular region that extends between the inner magnet and the second coil;
- and
- a plurality of support elements through the second annular region.
