Searches for weakly interacting massive particle (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 (NV) 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.

寻找弱相互作用的大质量粒子（WIMP）暗物质将在不久的将来对太阳中微子敏感。定向检测提供了一种拒绝太阳中微子并改善WIMP搜索的方法，但是使用现有的定向检测器达到这种灵敏度带来了挑战。我们提出了一种使用大容量金刚石探测器的原子/粒子物理学相结合的方法。WIMP候选事件触发了一个粒子检测器，此后氮空位（NV）中心的光谱法读出了进入粒子的方向。我们讨论了在钻石中实现定向检测所需的技术现状，并提出了一条通往灵敏度低于中微子底限的检测器的途径。
