Noah Kurinsky, Paul Brink, Richard Partridge, Blas Cabrera, Matt Pyle

摘要:

我们提出了SuperCDMS高电压,低质量暗物质探测器的技术设计,旨在敏感的暗物质下降到300 MeV/ $c^2$的质量和解决个别电子空穴对从低能量散射事件在高纯度的Ge和Si晶体。在本文中,我们讨论了一些研究和技术改进,使我们能够设计这样一个敏感的探测器,包括声子传感器的设计和探测器模拟的进展。通过这种设计,我们期望在我们的Ge(Si)探测器中实现优于10 eV(5 eV)的声子能量分辨率,并且通过利用Luke-Neganov声子产生在高场中加速的电荷来实现低于1 eV的反冲能量分辨率。

英文摘要:

We present the technical design for the SuperCDMS high-voltage, low-mass dark matter detectors, designed to be sensitive to dark matter down to 300 MeV/$c^2$ in mass and resolve individual electron-hole pairs from low-energy scattering events in high-purity Ge and Si crystals. In this paper we discuss some of the studies and technological improvements which have allowed us to design such a sensitive detector, including advances in phonon sensor design and detector simulation. With this design we expect to achieve better than 10 eV (5 eV) phonon energy resolution in our Ge (Si) detectors, and recoil energy resolution below 1eV by exploiting Luke-Neganov phonon generation of charges accelerated in high fields.
