X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Performance Analysis of Digital Flux-locked Loop Circuit with Different SQUID - Transfer Curves for TES Readout System
Nan Li, Xiang-xiang Ren, Le-peng Li +11
A superconducting quantum interference device (SQUID), functioning as a nonlinear response device, typically requires the incorporation of a flux-locked loop (FLL) circuit to facil…
Beyond One-Thousandth Energy Resolution with an AlMn TES Detector
Liangpeng Xie, Yifei Zhang, Zhengwei Li +10
The superconducting Transition-Edge Sensor (TES) is a critical technology for next-generation X-ray spectrometers, known for its exceptional energy resolution. In the last decade,…
Development of Low-Noise Two-stage dc-SQUID for TES Detector Readout
Nan Li, Mengjie Song, Sixiao Hu +9
Direct-current superconducting quantum interference devices (dc-SQUIDs) are one of the most sensitive magnetic detectors. These sensors are extensively used in the readout of super…
Fabrication and Characterization of X-ray TES Detectors Based on Annular AlMn Alloy Films
Yifei Zhang, Zhengwei Li, Mengxian Zhang +16
AlMn alloy flms are widely fabricated into superconducting transition edge sensors (TESs) for the detection of cosmic microwave background radiation. However, the application in X-…
Fabrication and characterization of AlMn alloy superconducting films for 0vbb experiments
Zhouhui Liu, Yifei Zhang, Yu Xu +13
Neutrinoless double-beta decay (0vbb) experiments constitute a pivotal probe for elucidating the characteristics of neutrinos and further discovering new physics. Compared to the n…
