Abstract
Abstract An electromagnet structure is described for producing highstrength magnetic fields. Individual layers of electrical coil layers are stacked on a support and comprise a coil structure. Each of the coil layers is individually reinforced against displacement away from the support by a wound reinforcing layer of material having substantial tensile strength.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
172 words
An electromagnet structure for producing high strength magnetic fields comprising a cylindrical tubular support defining a space in which the field is produced, a pair of saddle coil structures, said coil structures being positioned on opposite sides of said support aligned with each other on a common axis which is perpendicular with the axis of said support, each of said coil structures including a plurality of coil layers stacked on the outer surface of said support along said common axis, and a plurality of reinforcing layers of material having substantial tensile strength, said reinforcing layers each being comprised of a continuous strip anchored at both ends to said support and wrapped helically around said support and over a respective one of said coil layers in each coil structure to reinforce each individual coil layer of said electromagnet structure against strain in the presence of high strength magnetic fields, the turns of said strip being displaced from each other along the axis of said support to form a helical passage for coolant flow.
Claim 2
Dependent Claim
172 words
