在探索宇宙奥秘与解决能源危机的双重驱动下，自上世纪五六十年代起，人类开始将目光投向了核聚变 ——这一被誉为"人造太阳"的终极能源解决方案。核聚变，作为自然界中恒星发光发热的基本原理，其 能量释放巨大且几乎无放射性废物产生。如果拥有了它，人类长期面临的能源危机、碳排放等一系列问 题将迎刃而解。 挑战 本报记者 张炯强 近日，复旦大学举办了一场名为"聚核之光：启终极能源，筑未来之光"的论坛，探讨"人造太阳"何时到 来。复旦大学现代物理研究所/核科学与技术系教授许敏在演讲中指出，毫无疑问，核聚变带来的是清 洁、高效、可持续的理想能源。聚变能源的核心目标是突破"聚变三乘积"这一关键指标。全球科学家历 经数十年攻关，当前国内BEST建设，环流器三号升级改造等项目如火如荼，国外国际热核实验堆 （ITER）、美国国家点火装置（NIF）频传捷报，但仍面临三大核心挑战：燃烧等离子体稳态运行控 制、耐高能中子辐照和高热负荷材料、氚循环及氚自持。 许敏介绍，实现核聚变取决于三个要素——密度：足够多的反应粒子；离子温度：足够的能量；能量约 束时间：足够的能量保存。 核聚变燃料主要包括氘和氚，这些燃料在核聚变反应中释放出巨大的能量，具 ...

从核心参数来看，BEST主机直径18米、高19米，总重6000吨，重量仅为国际热核聚变实验堆（ITER） 的四分之一左右，但核心性能毫不逊色。其等离子体大半径3.6米、小半径1.1米，拉长比控制在1.7—1.9 之间，通过优化的磁场构型让能量更集中；环向磁场最大强度达6.15特斯拉，相当于地球磁场的12万 倍，能将上亿度的氘氚等离子体牢牢约束在真空室中，避免高温触碰装置内壁；等离子体电流可达到4 —7MA，聚变功率预计在20—200MW之间，足以支撑商业化发电的技术验证。尤为关键的是，BEST通 过高温超导混合磁体、精密控制技术的深度融合，实现了长脉冲持续运行能力——规划脉冲持续时间超 过1000秒，远超同类装置的短时放电模式，为聚变能商业化所需的"稳定供电"提供了关键实验基础。 技术内核 可控核聚变行业资深观察员，合肥太阿聚变科技有限公司 刘芳 翁竑 "把太阳的能量装进18米直径的'容器'，让上亿度等离子体稳定燃烧并转化为电能——这不是科幻，而 是合肥紧凑型聚变能实验装置BEST正在攻克的核心任务。"2025年5月1日，紧凑型聚变能实验装置 （BEST）项目的工程总装启动仪式在聚变堆主机关键系统综合研究设施 ...
