Abstract: A non-bonded, tape wound magnet includes a stack of disk coils, the disk coils having outer radius rd stacked on a z axis having opposing terminal ends. The disk coils include pancake-wound superconducting tape including a superconducting material and having a wound radius rsc. At least one disk coil at each opposing terminal end of the stack has overbanding positioned radially outward from the pancake wound superconducting tape. The overbanding has an elastic modulus and ultimate tensile strength at least 50% greater than the elastic modulus and ultimate tensile strength of the superconducting tape, and an electrical resistance at least 100% greater than that of the superconducting material, the overbanding having a radial dimension ro. The overbanding applies radial compression to the pancake wound superconducting tape. A method of making a magnet is also disclosed.

Abstract: A new type of vacuum balloon. A layered wall structure is used, including a relatively thick honeycombed section sandwiched between and bonded to two relatively thin layers. This layered wall design is used to form a thin-walled sphere having greatly enhanced resistance to buckling. Using this approach it is possible, with existing materials, to create a rigid vacuum balloon having positive buoyancy.

Abstract: A magnet for use with a neutron scattering apparatus. The neutron scattering apparatus provides an incident beam of neutrons to a sample under analysis. The magnet has first and second body portions of high conductivity material and has a mid-plane portion there between in which the sample under analysis is positioned. The first and second body portions of the coil are electrically connected to each other via the mid-plane portion of the coil between the body portions of the coil. The conductive mid-plane portion has a split that allows neutron scattering through large angles.
