Abstract

A thin superconducting solenoid magnet for the ATLAS detector in the CERN-LHC project is under construction as a cooperative work between KEK and CERN. A control dewar at the top of the detector is connected with a coil through a long chimney placed in the gap of the outer detectors and toroidal magnets. A set of superconducting bus lines and cooling tubes is arranged in the chimney. The fabrication of the chimney and the control dewar has been completed and the performance test was carried out. The current leads in the control dewar and the superconducting bus lines in the chimney were successfully tested with a current of 10 kA including 2 kA contingency. Quench characteristics of the bus was measured and also analyzed. A superconducting quench detector worked well to pick up quenches
