用于直接搜索暗物质的大质量液体Ar和Ar探测器

Massive liquid Ar and Xe detectors for direct Dark Matter searches

B. M. Ovchinnikov, Yu. B. Ovchinnikov, V. V. Parusov

摘要:

提出了一种新的直接寻找暗物质的实验方案,即采用液态氩质量达几百吨的液态氩双相室。为了抑制b-,g-和n0-背景,闪烁和电离信号的比较,为每个事件的建议。在液体Ar中加入光敏Ge(CH 3)4或C2H4和抑制闪烁信号的三重态分量确保了高效率地检测闪烁信号,并提供了对电子背景的完全抑制。为了检测光电子和电离电子,必须使用高度稳定和可靠的GEM检测器。

英文摘要:

A novel experiment for direct searches of the Dark Matter with liquid argon double-phase chamber with a mass of liquid Ar up to several hundred tons is proposed. To suppress the b-, g- and n0- backgrounds, the comparison of scintillation and ionization signals for every event is suggested. The addition in liquid Ar of photosensitive Ge(CH3)4 or C2H4 and suppression of triplet component of scintillation signals ensures the detection of scintillation signals with high efficiency and provides a complete suppression of the electron background. For the detection of photoelectrons and ionization electrons, highly stable and reliable GEM detectors must be used.
