未来10万吨级液氩探测器的研制

R&D for Future 100 kton Scale Liquid Argon Detectors

A. Marchionni

摘要:

目前正在考虑将100千吨级的大型液氩探测器用于质子衰变研究和中微子天体物理学,并考虑将其用作下一代长基线中微子振荡实验的远探测器,目的是确定中微子质量等级和在轻子区进行CP破坏研究。这些检测器依赖于在低温条件下以低热损失稳定地维持大LAr质量和实现电离电荷的长漂移的可能性,从而使每单位体积的读出通道的数量最小化。世界各地正在开展许多研发活动,最终探测器设计的概念略有不同,但有许多共同的基本研发问题。

英文摘要:

Large liquid argon (LAr) detectors, up to 100 kton scale, are presently being considered for proton decay searches and neutrino astrophysics as well as far detectors for the next generation of long baseline neutrino oscillation experiments, aiming at neutrino mass hierarchy determination and CP violation searches in the leptonic sector. These detectors rely on the possibility of maintaining large LAr masses stably at cryogenic conditions with low thermal losses and of achieving long drifts of the ionization charge, so to minimize the number of readout channels per unit volume. Many R&D initiatives are being undertaken throughout the world, following somewhat different concepts for the final detector design, but with many common basic R&D issues.
