AI 中文摘要
与超导量子干涉器件（SQUID）耦合的过渡边缘传感器（TES）探测器的读出电子设备中会发生通量跳变，这是超导状态下SQUID周期性传递函数导致的结果。这些事件表现为时间序数据（TOD）中的不连续性，会显著降低测量信号的质量。本研究中，我们提出了一种自动流水线，用于识别和校正QUBIC（宇宙学Q与U bolometric干涉仪，Q & U Bolometric Interferometer for Cosmology）仪器校准数据中的通量跳变，该仪器旨在测量宇宙微波背景（CMB）的B模式偏振。我们利用多个观测 campaign 的数据，表征了通量跳变的统计特性，并将其与基于仪器电子配置的预期进行比较。所提出的流水线成功校正了这些事件，使受影响的数据得以恢复，并可用于后续的CMB分析。
英文摘要
Flux jumps occur in the readout electronics of Transition Edge Sensor (TES) detectors coupled to Superconducting Quantum Interference Devices (SQUIDs), as a consequence of the periodic transfer function of SQUIDs in the superconducting regime. These events manifest as discontinuities in the Time Ordered Data (TOD) and can significantly degrade the quality of the measured signals. In this work, we present an automated pipeline to identify and correct flux jumps in the calibration data of the QUBIC (Q \& U Bolometric Interferometer for Cosmology) instrument, designed to measure the B-mode polarization of the Cosmic Microwave Background (CMB). Using data from multiple observation campaigns, we characterize the statistical properties of flux jumps and compare them with expectations based on the electronic configuration of the instrument. The proposed pipeline successfully corrects these events, allowing the recovery of affected data and enabling their use in subsequent CMB analysis.
