摘要:

EDELWEISS合作的目标是使用锗低温探测器直接探测光暗物质,该探测器具有低阈值声子传感器技术和高效的电荷读出设计。我们在这里描述的发展,锗测辐射热计配备高阻抗热敏电阻的基础上NbxSi 1-x TES合金。高纵横比螺旋设计允许TES阻抗与JFET或HEMT前端放大器匹配。我们详细介绍了这些传感器和检测器优化的灵敏度,平衡声子的超导过渡特性的行为。我们报告的初步结果,200克锗探测器,校准使用71锗激活中子在LSM地下实验室。

英文摘要:

The EDELWEISS collaboration aims for direct detection of light dark matter using germanium cryogenic detectors with low threshold phonon sensor technologies and efficient charge readout designs. We describe here the development of Ge bolometers equipped with high impedance thermistors based on a NbxSi1-x TES alloy. High aspect ratio spiral designs allow the TES impedance to match with JFET or HEMT front-end amplifiers. We detail the behavior of the superconducting transition properties of these sensors and the detector optimization in terms of sensitivity to out-of-equilibrium phonons. We report preliminary results of a 200 g Ge detector that was calibrated using 71Ge activation by neutrons at the LSM underground laboratory.
