A thin superconducting solenoid magnet for the WASA detector

A thin superconducting solenoid magnet has been developed for the WASA detector. The magnet consists of a pair of coils and it provides a central magnetic field of 1.3 T at 900 A in a cylindrical volume of 0.65 m in diameter and 0.555 m in length. The features of this solenoid magnet are the excellent transparency for particles, conducting cooling, thermo siphon method, applying aluminum strip for conduction cooling and corrugated outer wall. Recently, the performance test was successfully carried out. In this report, magnet design and fabrication of the WASA superconducting solenoid magnet will be presented and the test results will be described.
