Abstract
Many different magnetic measurements require a large ac. magnetic field to be produced in a high background dc. magnetic field This paper describes the design, construction and performance of an ac. superconducting Nb3Sn coil. It is wound on a non-magnetic, non-metallic former that is made from silica glass and a machinable glass ceramic. The coil is 216 mm long with an outer diameter of 38 mm and an inner diameter of 18 mm. It is made in two sections, wound coaxially, which are configured in the opposite sense to reduce the coupling between the coil producing the ac. field and the dc. magnet. The coil is able to produce high ac. fields in a 40 mm bore, 17 T magnet. In a dc. field of 12 T the coil can produce 340 mT at 1 Hz and 85 mT at 20 Hz.
