CRESST-III实验寻找暗物质与普通物质的直接相互作用。主要事件的标志是其中一个结晶CaWO 4晶体内的核反冲。将晶体作为低温量热计操作，提供声子信号作为沉积能量的量度。两个信号的同时读出用于主动区分背景。CRESST-III侧重于亚GeV/c2质量区域，其中灵敏度由阈值驱动。在2016-2018年CRESST-III的第一次数据采集活动中，获得了前所未有的30.1 eV的核反冲阈值。在这篇文章中，我们将报告实验的状态和最新结果。
The CRESST-III experiment searches for direct interactions of dark matter with ordinary matter. The main event signature would be a nuclear recoil inside one of the scintillating CaWO4 crystals. Operating the crystals as cryogenic calorimeters provides a phonon signal as measure of the deposited energy. The simultaneous readout of both signals is used to actively discriminate backgrounds. CRESST-III focuses on the sub-GeV/c2 mass region where the sensitivity is driven by the threshold. In the first data taking campaign of CRESST-III from 2016-2018 an unprecedented low threshold of 30.1 eV for nuclear recoils was obtained. In this contribution, we will report the status of the experiment and the latest results.
