论文摘要
在这项工作中，我们报告了第一个使用钻石作为Astroparpicle物理应用吸收剂的低阈值低温检测器的实现。我们测试了两个0.175 $ \，$ G CVD钻石样品，每个样品都带有W-TES。传感器显示约25 mk的过渡。我们介绍了钻石探测器的性能，并突出了表现最好的钻石探测器，在那里我们获得了低至16.8 eV的能量阈值。这一有希望的结果为在不同的应用领域中使用钻石的基础是需要低阈值和优异能量分辨率的不同领域的基础，即光线暗物质搜索和具有连贯的弹性中微子核散射的BSM物理学。
In this work we report the realization of the first low-threshold cryogenic detector that uses diamond as absorber for astroparticle physics applications. We tested two 0.175$\,$g CVD diamond samples, each instrumented with a W-TES. The sensors showed transitions at about 25 mK. We present the performance of the diamond detectors and we highlight the best performing one, where we obtained an energy threshold as low as 16.8 eV. This promising result lays the foundation for the use of diamond for different fields of applications where low threshold and excellent energy resolution are required, as i.e. light dark matter searches and BSM physics with coherent elastic neutrino nucleus scattering.
