提出了一种用于超导体暂态稳定性测量的小型陶瓷片式电阻器。使用1 mm*1.5 mm*0.5 mm陶瓷电阻器和NbTi线获得了初步结果，其铜与超导体（Cu/SC）的比率为1和2，具有相同的SC面积。电阻器被焊接在NbTi线上以最小化电阻器和线之间的热阻。在相同的背景磁场和相同的工作电流与临界电流之比下，Cu/SC比2的导线的最小失超能量大约是Cu/SC比1的导线的两倍。
A small ceramic chip resistor is proposed as a possible ideal point heater for transient stability measurements of superconductors. Preliminary results were obtained using a 1-mm*1.5-mm*0.5-mm ceramic resistor and NbTi wires whose copper-to-superconductor (Cu/SC) ratios were 1 and 2, having the same SC areas. The resistor was soldered on the NbTi wire to minimize the thermal resistance between the resistor and the wire. The minimum quench energy of the Cu/SC ratio 2 wire was approximately twice as large as that of the Cu/SC ratio 1 wire, under the same background magnetic field and with the same ratio of the operating current to its critical current.
