摘要: 热扰动是空间引力波探测最重要的干扰来源之一, 为满足中国空间引力波探测“太极计划”的需求, 需要保证探测器光学干涉平台所在区域温度波动优于10 μK·Hz–1/2 @ 0.1 mHz～1 Hz, 这需要μK·Hz–1/2的温度测量技术. 针对空间引力波探测对高分辨率测温技术的需求, 研制了一套基于惠斯通电桥的多激励源的测温电桥实验装置. 讨论了测温电桥的激励源及其他组件的设计方案, 并进行了恒压源、恒流源和交流源激励下的测温电桥本底噪声的实验验证. 结果表明, 在三种激励源分别激励电桥时, 交流源结合锁相读出技术相较其他两种激励源能够达到更低的本底噪声, 且在30 mHz～1 Hz频率范围内的噪声优于10 μK·Hz–1/2, 基本能满足“太极探路者”的指标要求, 对太极计划后续μK·Hz–1/2级温度测量系统的研制提供了重要参考.Abstract: Thermal disturbance is one of the most important sources of interference for spatial gravitational wave detection. To meet the needs of the Taiji program for spatial gravitational wave detection, it is necessary to ensure that the temperature fluctuation in the area where the detector's optical interference platform is located is better than 10 μK·Hz–1/2 at frequencies between 0.1 mHz and 1 Hz. This requires μK·Hz–1/2 temperature measurement technology. In response to the need for high-resolution temperature measurement technology in spatial gravitational wave detection, this paper has developed an experimental setup for a temperature measurement bridge with multiple excitation sources based on the Wheatstone bridge. The design of the excitation sources and other components of the temperature measurement bridge is discussed, and experimental verification of the noise floor of the temperature measurement bridge under excitation from constant voltage sources, constant current sources, and alternating current sources is conducted. The experimental results show that when the bridge is excited by the three excitation sources, the alternating current source combined with phase-locked readout technology can achieve lower background noise compared to the other two excitation sources. The noise is better than 10 μK·Hz–1/2 in the frequency range of 30 mHz to 1 Hz, basically meeting the requirements of the Taiji Pathfinder. This provides an important reference for the subsequent development of the μK·Hz–1/2-level temperature measurement system for the Taiji program.
