论文摘要
Edelweiss协作通过收集电荷和声子信号进行轻暗（DM）颗粒搜索。多亏了Neganov-Trofimov-Luke（NTL）效应，在用NBSI过渡边缘传感器（TES）仪器（TES）仪器（在Laborato Souterrain de Modane（LSM）上运行的NBSI过渡边缘传感器（TES）仪器（TES）上，获得了4.46个电子孔对的RMS分辨率。这种敏感性使使用Migdal效果降低到32 MeV/c $^{2} $可以搜索WIMP，并将横截面降至10 $^{ - 29} $ cm $^2 $。这是具有这种热传感器的低温锗中的第一个测量，证明了该技术的高相关性。此外，这样的TE对异常的声子表现出敏感性，为Edelweiss New Sperience Cryosel铺平了道路。这是在Edelweiss-Subgev计划中具有提高性能的开发开发GE检测器的重要一步。
The Edelweiss collaboration performs light Dark Matter (DM) particles searches with germanium bolometer collecting charge and phonon signals. Thanks to the Neganov-Trofimov-Luke (NTL) effect, a RMS resolution of 4.46 electron-hole pairs was obtained on a massive (200g) germanium detector instrumented with a NbSi Transition Edge Sensor (TES) operated underground at the Laboratoire Souterrain de Modane (LSM). This sensitivity made possible a search for WIMP using the Migdal effect down to 32 MeV/C$^{2}$ and exclude cross-sections down to 10$^{-29}$ cm$^2$. It is the first measurement in cryogenic germanium with such thermal sensor, proving the high relevance of this technology. Furthermore, such TES have shown sensitivity to out-of-equilibrium phonons, paving the way for EDELWEISS new experience CRYOSEL. This is an important step in the development of Ge detectors with improved performance in the context of the EDELWEISS-SubGeV program.
