直接探测Sub-GeV暗物质的金刚石探测器
Diamond Detectors for Direct Detection of Sub-GeV Dark Matter
摘要：
我们建议使用高纯度的实验室生长的金刚石的亚GeV的暗物质的检测。金刚石靶可以对来自MeV及以上质量范围内的暗物质散射的核反冲和电子反冲敏感，以及对质量在亚eV至数十eV之间的暗物质的吸收过程敏感。与其他提出的半导体目标（如锗和硅）相比，金刚石探测器可以通过碳核的轻而产生的核反冲探测较低质量的暗物质。电子反冲的预期范围可与锗和硅的电子反冲的预期范围相媲美，其优点是预期暗计数处于更好的控制之下。通过吸收过程，无约束的QCD轴子参数空间可以成功地探测在金刚石质量为10 eV，进一步证明了我们的方法的力量。
英文摘要：
We propose to use high-purity lab-grown diamond for the detection of sub-GeV dark matter. Diamond targets can be sensitive to both nuclear and electron recoils from dark matter scattering in the MeV and above mass range, as well as to absorption processes of dark matter with masses between sub-eV to 10's of eV. Compared to other proposed semiconducting targets such as germanium and silicon, diamond detectors can probe lower dark matter masses via nuclear recoils due to the lightness of the carbon nucleus. The expected reach for electron recoils is comparable to that of germanium and silicon, with the advantage that dark counts are expected to be under better control. Via absorption processes, unconstrained QCD axion parameter space can be successfully probed in diamond for masses of order 10 eV, further demonstrating the power of our approach.
