由于地球通过银河暗物质晕的运动，定向重建提供了一种独特的方法来积极识别暗物质粒子引起的信号相互作用。方向信息还可以作为对具有与信号相互作用相同的最终状态特征的中子（和中微子引起的）背景的有力判别。暗物质时间投影室 (DMTPC) 合作使用基于气体的 TPC 技术，具有光学和电荷读出功能，来测量穿过探测器体积的粒子引起的核反冲的方向各向异性。在这里，我们展示了 DMTPC m3 探测器最近在表面实验室校准运行的初步结果，以及对其预计方向灵敏度的研究。
Directional reconstruction provides a unique way to positively identify signal interactions induced by dark matter particles, owing to the motion of the Earth through the galactic dark matter halo. Directional information can additionally serve as a powerful discriminant against neutron (and neutrino-induced) backgrounds that have the same final-state signature as a signal interaction. The Dark Matter Time Projection Chamber (DMTPC) collaboration uses gas-based TPC technology, with both optical and charge readout, to measure the directional anisotropy of nuclear recoils induced by particles traversing the detector volume. Here, we present preliminary results from recent calibration runs of the DMTPC m3 detector in a surface laboratory, as well as a study of its projected directional sensitivity.
