Directional detection of dark matter with diamond

Mason C. Marshall, Matthew J. Turner, Mark J. H. Ku, David F. Phillips, Ronald L. Walsworth

摘要:

在不久的将来,WIMP暗物质将对太阳中微子敏感。定向探测提供了一种拒绝太阳中微子和改善WIMP搜索的方法,但现有定向探测器达到这种灵敏度带来了挑战。我们提出了一种结合原子/粒子物理方法,使用大体积的金刚石探测器。WIMP候选事件触发粒子探测器,之后氮空位中心的光谱学读取进入粒子的方向。我们讨论了目前的技术状态,需要实现定向检测钻石,并提出了一个探测器的灵敏度低于中微子地板的路径。

英文摘要:

Searches for WIMP dark matter will in the near future be sensitive to solar neutrinos. Directional detection offers a method to reject solar neutrinos and improve WIMP searches, but reaching that sensitivity with existing directional detectors poses challenges. We propose a combined atomic/particle physics approach using a large-volume diamond detector. WIMP candidate events trigger a particle detector, after which spectroscopy of nitrogen vacancy centers reads out the direction of the incoming particle. We discuss the current state of technologies required to realize directional detection in diamond and present a path towards a detector with sensitivity below the neutrino floor.
