论文摘要
在实验室中创建磁化的相对论血浆将使探索与宇宙中一些最有活力的事件相关的独特等离子体物理学。作为迈向实验室对等离子体的一步，我们已经证明了在一个脉冲驱动的$ 13 $ $ $ \ mathrm {t} $磁性镜面的有效限制，以$ 2.6 $ 2.6 $。通过测量磁光谱仪的轴向和径向损耗来诊断限制。损耗光谱与$ \ leq 2.5 $ $ \ $ \ mathrm {mev} $电子限制在镜子中的$ \ sim 1 $ $ \ mathrm {ns} $。凭借可比能量的$ 10^{12} $电子 - 峰值对，这款磁性镜将相对论对等离子体与Lorentz因子$γ\ SIM 6 $ 6 $和磁化$σ\ SIM 40 $相对。
Creating magnetized relativistic pair plasma in the laboratory would enable the exploration of unique plasma physics relevant to some of the most energetic events in the universe. As a step towards a laboratory pair plasma, we have demonstrated effective confinement of multi-$\mathrm{MeV}$ electrons inside a pulsed-power-driven $13$ $\mathrm{T}$ magnetic mirror field with a mirror ratio of $2.6$. The confinement is diagnosed by measuring the axial and radial losses with magnetic spectrometers. The loss spectra are consistent with $\leq 2.5$ $\mathrm{MeV}$ electrons confined in the mirror for $\sim 1$ $\mathrm{ns}$. With a source of $10^{12}$ electron-positron pairs at comparable energies, this magnetic mirror would confine a relativistic pair plasma with Lorentz factor $γ\sim 6$ and magnetization $σ\sim 40$.
