摘要

潘多拉项目提出了一种新的实验方法,旨在利用实验室磁等离子体(模拟一些恒星条件)作为等离子体内β衰变研究的环境。在超导潘多拉陷阱中,含有已知浓度β衰变原子的热等离子体可以被限制并保持动态平衡数周。衰变率可以通过探测子核发射的γ射线来测量(通过HPGe探测器阵列),并使用多诊断系统与放射性离子的电荷态分布和等离子体的热力学性质相关联,本文介绍了多诊断系统的工具和技术。

Laboratory magnetoplasmas as an ideal experimental environment for nuclear astrophysics β-decay studies
The PANDORA project proposes a new experimental approach aimed at using laboratory magnetoplasmas (which emulate some stellar conditions) as an environment for in-plasma β-decays investigations. In the superconducting PANDORA trap, a hot plasma containing a known concentration of β-decaying atoms can be confined and kept in dynamic equilibrium for weeks. The decay rate can be measured by detecting the γ-rays emitted by the daughter nuclei (through HPGe detector array) and correlated with the charge state distribution of radioactive ions and with the plasma thermodynamic properties using a multi-diagnostic system, whose tools and techniques are here presented.
