Abstract

The thin solenoid for the Zeus detector has been installed and tested in HERA (Hadron Electron Ring Accelerator) at DESY. The coil reached the design magnetic field (1.8 T in the center) without training. During the test some measurements were made in order to investigate the cooling system and the quench-back behavior. No spontaneous quenches occurred. Several induced fast discharges showed the evidence of a quench-back effect, and the quench-back starting time was less than 1 s. The cylinder temperature measurements during the coil discharge perfectly agree with adiabatic calculations. The indirect cooling efficiency was verified for the two-layer winding. The tests performed showed that the magnet can operate safely at the nominal field
