coilwind

An undergraduate student guides the superconducting wire onto the winding form of the magnet coil-winding machine. The wire is made of a niobium and titanium compound imbedded in a copper matrix. The wire becomes superconducting at a temperature of -443 °F or 9.5 Kelvin. All of the hundreds of superconducting magnets needed to guide the particle beam from the cyclotron to the experiments have been designed and manufactured at NSCL. The coil in the picture will become part of a quadrupole magnet, which focuses the particle beam in the A1900 fragment separator.
