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 buoyancy system for an underwater autonomous vehicle is provided. The buoyancy system includes one or more pressure vessels, a primary pump connected to each of the one or more pressure vessels with the primary pump configured to pump liquid from the one or more pressure vessels. The buoyancy system further includes a controller communicatively coupled to the primary pump and configured to operate the main pump via wireless or wired communication, and a power source configured to provide power to the controller and the primary pump.
