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…
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…
The Sliding Flux Ramp Demodulation Algorithm with High Sampling Rate in Microwave SQUID Multiplexer
Guofu Liao, Congzhan Liu, Zhengwei Li +12
Microwave SQUID Multiplexing (uMUX) is a widely used technique in the low temperature detectors community as it offers high capacity of reading out large scale Transition-Edge Sens…
