将低温锗基暗物质探测器扩展到探测更小的wimp -核子截面，在增加劳动力、冷硬件、热电子和热负荷等方面提出了重大挑战。更大晶体的发展缓解了这些问题。本文介绍了两个直径为100mm，厚度为33mm的圆柱形探测级锗晶体的电离实验结果。通过这些结果，证明了在超低温暗物质搜索（SuperCDMS） SNOLAB实验中使用这种晶体的潜力。
Scaling cryogenic Germanium-based dark matter detectors to probe smaller WIMP-nucleon cross-sections poses significant challenges in the forms of increased labor, cold hardware, warm electronics and heat load. The development of larger crystals alleviates these issues. The results of ionization tests with two 100 mm diameter, 33 mm thick cylindrical detector-grade Germanium crystals are presented here. Through these results the potential of using such crystals in the Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB experiment is demonstrated.
