A superconducting magnet with 200 kJ stored energy and 150 A nominal current has been designed and manufactured. The magnet consists of two coaxial coils, counter-series connected in order to keep the stray field below a given limit. The SC wire is a copper stabilized Ni-Ti strand, coated with an insulating glass yarn. Several copper slabs are placed within the coils in order to permit heat removal deep within the coil, thus allowing the device to operate at high AC losses regime. The device is addressed to innovative power system control aNd stabilization. Several tests with different ramp rate have been carried out at the liquid helium temperature. Design and manufacturing characteristics as well as test results are presented in this paper.

Abstract
A superconducting magnet with 200 kJ stored energy and 150 A nominal current has been designed and manufactured. The magnet consists of two coaxial coils, counter-series connected in order to keep the stray field below a given limit. The SC wire is a copper stabilized Ni-Ti strand, coated with an insulating glass yarn. Several copper slabs are placed within the coils in order to permit heat removal deep within the coil, thus allowing the device to operate at high AC losses regime. The device is addressed to innovative power system control aNd stabilization. Several tests with different ramp rate have been carried out at the liquid helium temperature. Design and manufacturing characteristics as well as test results are presented in this paper.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
