Abstract
A gradient coil or other element of a magnetic resonance imaging system includes at least one layer comprised of copper having a first surface and a second surface. A first semiconductor layer is applied to the first surface of the copper and an insulation layer applied to the first semiconductor layer. In one embodiment, a second semiconductor layer is applied to the second surface of the copper. The first and second semiconductor layers encapsulate any voids formed between the copper and the semiconductor layers, equalize the potential around the voids and prevent partial discharge formation.
