英文摘要	a model coil for 40-t hybrid magnet superconducting outsert magnet has been constructed and tested at the high magnetic field laboratory, chinese academy of sciences. the model coil was wound with nb3sn cable-inconduit conductor (cicc) cabled in a 316ln jacket cooled with supercritical helium. the model coil alone can produce about 4 t maximum magnetic field with an operating current of 14 ka. the model coil, in combination with 7.57-t nbti background coil, can produce 11.5 t central field at 14 ka. during the test campaigns, a fast discharge was triggered by a dump resistor of 3.6 m to evaluate the thermalelectromagnetic behavior of the model coil. in order to avoid a quench of the background coil, no current was exerted on the background coil through a power supply during the fast discharge of the model coil. the test results show that the central magnetic field is not scaled proportionally to the current decay of the model coil. the circuit model gives excellent results compared with the measured ones for the central magnetic field evolution as a function of time in this paper. for the thermal-hydraulic behavior during the fast discharge, the maximum temperature at the inlet simulated by the 1-d gandalf code gives excellent agreement results compared with the measured ones with the conductor coupling time constant of 63 ms.
