Abstract

In recent years, there has been increasing interest in developing detectors which are sensitive to sub-GeV dark matter and low-energy events from coherent neutrino scattering. Due to carbon’s light atomic weight and its tendency to form crystals with high-energy, long-lived phonon modes, carbon-based crystals (including diamond and silicon carbide (SiC)) present themselves as natural target materials for scattering-based searches in this regime. We present our preliminary results in adapting our TES-based detectors to these substrates, specifically 4-H SiC and polycrystalline diamond. We focus on our fabrication efforts, specifically tuning the transition temperature (\(\text {T}_{\text {C}}\)) of tungsten films sputtered on these materials, as well as our advancement toward fabricating and testing devices on these substrates.

用于罕见事件搜索的钻石和碳化硅探测器
近年来,越来越多的人开始关注开发对亚 GeV 暗物质和相干中微子散射产生的低能事件敏感的探测器。由于碳的原子质量很轻,而且容易形成具有高能量、长寿命声子模式的晶体,碳基晶体(包括金刚石和碳化硅(SiC))自然而然地成为在这一机制下进行基于散射搜索的目标材料。我们介绍了将基于 TES 的探测器应用于这些基底(特别是 4-H 碳化硅和多晶金刚石)的初步成果。我们将重点介绍我们的制造工作,特别是调整在这些材料上溅射的钨薄膜的转变温度(\(\text {T}_{text {C}}\) ),以及我们在这些基底上制造和测试设备的进展。
