摘要:

直接暗物质搜索使用完全耗尽的高电阻率CCD探测器。由于它们的低电子读出噪声(RMS ~ 7 eV),这些设备以40 eV的非常低的检测阈值工作,使得寻找低质量(~ 5 GeV)的暗物质粒子成为可能。在一个浅的地下场地进行的工程运行的结果,展示了这种技术在低质量区域的潜力。

英文摘要:

A direct dark matter search is performed using fully-depleted high-resistivity CCD detectors . Due to their low electronic readout noise (RMS ~ 7 eV) these devices operate with a very low detection threshold of 40 eV, making the search for dark matter particles with low masses (~ 5 GeV) possible. The results of an engineering run performed in a shallow underground site are presented, demonstrating the potential of this technology in the low mass region.
