✦ Synopsis

A prototype thin superconducting solenoidal magnet for the SDC detector (Solenoidal Detector Collaboration for the former SSC project) was developed. The magnet was cooled down and excited up to 12,000A in the performance test at KEK. The magnet is 3.8 m in diameter, 2 m in length with a total cold mass of 4.5 tonnes. It was cooled by using indirect two-phase helium flow passing through a 64 m serpentine cooling path. The hydrodynamic characteristics has been investigated. The measured result and preliminary analysis are discussed.
