论文摘要
可移动的温度剖面是24个传感器的7 m垂直阵列，该阵列的精度为几mK，可以测量低温温度。该精度对于监测大型基于阿贡的大型中微子探测器内的液体 - 阿贡的再循环和纯化的效率是必要的。液体氩温度会影响电子（信号）漂移速度，流量，纯度分布以及总体能量校准。温度剖面机电动并垂直移动，而在检测器中，并进行了交叉校准相邻的传感器。每个传感器之间的温度偏移取消电磁噪声的影响。该海报报告了在CERN处的原始调整（单相）处的温度测量值和原位横振。
The movable temperature profiler is a 7 m vertical array of 24 sensors that measures cryogenic temperatures with a precision of a few mK. This precision is necessary to monitor the efficiency of re-circulation and purification of liquid-argon inside large liquid-argon based neutrino detectors. Liquid argon temperature impacts electron (signal) drift velocity, flow, purity distribution and thus the overall energy calibration. The temperature profiler is motorized and moves vertically, while in the detector, and cross-calibrates neighboring sensors. The temperature offsets between each sensor cancel the effects of electromagnetic noise. This poster reports on the temperature measurements and such in-situ cross-calibrations at ProtoDUNE (single phase) at CERN.
