论文摘要
使用改良的商业步进电动机在Millikelvin温度下运行了能够将放射性校准源转移到多个位置的原型设备。它是为低温暗物质探测器的原位校准策略而开发的。通过在原型暗物质检测器的多个径向位置扫描校准源获取的数据显示了其功能。讨论了设备的结构，热负荷和操作，电动机对检测器操作的影响也是如此。列出了超级cdms检测器的多个位置的样本数据集，作为该设备实用程序的一个示例。
A prototype device capable of moving a radioactive calibration source to multiple positions was operated at millikelvin temperatures using a modified commercial stepper motor. It was developed as an in-situ calibration strategy for cryogenic dark matter detectors. Data taken by scanning a calibration source across multiple radial positions of a prototype dark matter detector demonstrated its functionality. Construction, heat load, and operation of the device are discussed, as is the effect of the motor on the detector operation. A sample dataset taken over multiple positions of a SuperCDMS detector is presented as an example of the utility of such a device.
