AI 中文总结

LM26磁化靶聚变装置通过锂套筒压缩球形托卡马克等离子体,实现电子温度超1 keV,离子温度显著提升,相关综合观测为该领域重要里程碑。

AI 中文摘要

LM26装置通过滤波X射线二极管测得的峰值电子温度为$T_e = 1180 \pm 65$ eV,相邻汤姆逊散射测量支持该结果,测得$T_e = 1090 \pm 40$ eV,由中子产额推断氘离子温度为$T_i = 459 \pm 33$ eV。LM26通过θ箍缩线圈驱动初始直径1.76 m的固体锂套筒内爆,压缩球形托卡马克等离子体,径向压缩比达2.75,使$T_e$提升5倍以上,$T_i$提升最多2倍。对大型锂套筒压缩磁化等离子体过程中磁通量压缩、电子加热、离子加热及中子产生的综合观测,是磁化靶聚变领域的重要里程碑。

英文摘要

The LM26 device has achieved a peak electron temperature of $T_e = 1180 \pm 65$ eV as measured by filtered X-ray diodes, supported by adjacent Thomson scattering measurements of $T_e = 1090 \pm 40$ eV, with a deuterium ion temperature of $T_i = 459 \pm 33$ eV as inferred from neutron yield. LM26 compresses a spherical tokamak plasma inside an initially 1.76 m diameter solid lithium liner imploded by theta-pinch coils. Radial compression by a factor of 2.75 increases $T_e$ over fivefold, while $T_i$ increases as much as twofold. The integrated observation of magnetic flux compression, electron heating, ion heating, and neutron production in a magnetized plasma compressed by a large lithium liner is an important milestone for magnetized target fusion
