Lawson Simulation Lab劳逊模拟实验室
Drive density, ion temperature, and confinement time. Watch the triple product cross the ignition line. Switch fuel from D-T to D-D to p-B11 and see why the aneutronic dream is 500× harder.拖动密度、离子温度、约束时间,看三乘积越过点火线。从氘氚切到氘氘再到氢硼,亲手验证「无中子化」的梦想为什么难 500 倍。
Reading解读
For D-T fuel, ignition (Q→∞) requires a triple product of about 3×10²¹ keV·s/m³. Tokamaks raise nτE through magnetic confinement at moderate T; ICF crashes to enormous n at vanishingly small τE for a few hundred picoseconds — both legal solutions to Lawson.氘氚燃料的点火(Q→∞)要求三乘积约 3×10²¹ keV·s/m³。 托卡马克通过磁约束在中等温度下抬高 nτE; 惯性约束聚变则在数百皮秒内把 n 推到极高、τE 极小—— 两条路径都满足 Lawson 判据。

Fusion University聚变大学
The eight foundational ideas, each in one card and one equation: Lawson, β, alpha-heating, q, TBR, DPA, RL plasma control, and why HTS magnets changed everything.八个基础概念,每个一卡一方程:劳逊判据、β、α 加热、q 因子、氚增殖比、DPA、强化学习等离子体控制,以及 HTS 磁体为何改变一切。
The Lawson criterion劳逊判据
Lawson asked the simplest question of fusion: when does the reaction sustain itself? The answer balances three numbers — particle density n, temperature T, and the time τE the plasma can hold its energy before it leaks out. Below the line, you spend more energy than you make. Above it, the plasma feeds itself.Lawson 提出了聚变最朴素的问题:反应何时能自持?答案要让三件事达成平衡——粒子密度 n、温度 T、以及等离子体在能量泄漏出去之前能维持的时间 τE。线之下你输的比赚的多;线之上,等离子体自我供养。
Plasma β: how much pressure your bottle holds等离子体 β:磁瓶能装多少压强
β measures plasma pressure against the magnetic pressure that holds it. β=1 means the plasma's own pressure equals the field's. Most tokamaks operate at β=2-5%. Push higher and instabilities devour the plasma. Spherical tokamaks reach β≈40% — the prize, and the danger.β 衡量等离子体压强相对于约束它的磁压。β=1 意味二者相等。大多数托卡马克在 β=2-5% 区间运行;再推高,不稳定性会吞噬等离子体。球形托卡马克可达 β≈40%——既是奖赏,也是危险。
Alpha-particle self-heatingα 粒子自加热
When a D-T reaction fires, the 14.1 MeV neutron escapes — but the 3.5 MeV alpha (a helium-4 nucleus) carries 20% of the energy and is trapped by the magnetic field. Above Q≈5, alphas alone heat the plasma faster than it cools. This is the threshold called 'burning plasma'.氘氚反应触发时,14.1 MeV 中子飞走——但 3.5 MeV α 粒子(氦-4 核)带走 20% 的能量并被磁场俘获。Q≈5 以上时,α 粒子单凭自身加热的速度就超过冷却速度。这就是所谓「燃烧等离子体」的门槛。
The safety factor q安全因子 q
q counts how many toroidal trips a magnetic field line takes per poloidal trip. q<1 in the core invites the sawtooth instability; q at the edge governs ELMs and disruptions. The whole magnetic shaping of a tokamak is a fight to keep q profiles where they don't murder the plasma.q 表示磁力线每绕一圈极向时绕了多少圈环向。芯部 q<1 会引发锯齿不稳定;边界 q 决定边界局域模与破裂。整个托卡马克的磁形塑造,都是在跟 q 廓线博弈,避免它把等离子体杀掉。
Tritium breeding ratio (TBR)氚增殖比(TBR)
Tritium has a 12.3-year half-life and no large natural source. Every D-T plant must breed its own from lithium in a blanket surrounding the plasma. TBR > 1 is the condition for fuel self-sufficiency. No power plant has yet demonstrated it; the materials, geometry, and neutron multiplication for TBR ≥ 1.05 are the central engineering bet.氚的半衰期 12.3 年,自然界无大规模来源。每座 D-T 电站都必须自行用锂在等离子体周围的包层中增殖氚。TBR>1 是燃料自给的条件。至今无一电站演示过它;要实现 TBR ≥ 1.05 所需的材料、几何与中子倍增,是核心工程赌注。
Neutron damage in DPA中子损伤(DPA)
First-wall components in a D-T plant absorb 14 MeV neutrons constantly. Damage is measured in displacements per atom (DPA): how many times each atom in the lattice has been knocked off its site. Tungsten survives ~50 DPA. ITER will accumulate ~3 DPA in its lifetime; a power plant first wall must endure 100+ DPA. This drives the entire reduced-activation steel programme.D-T 电站第一壁组件不断吸收 14 MeV 中子。损伤以「每原子位移次数」(DPA)衡量:晶格中每个原子被撞离原位的次数。钨可承受约 50 DPA。ITER 全寿命累积约 3 DPA;电站第一壁须撑过 100+ DPA。整个低活化钢研发都是为此驱动。
RL plasma shape control强化学习等离子体形状控制
DeepMind & EPFL/SPC showed in 2022 that a single RL policy can control the magnetic actuators of TCV to drive the plasma into shapes — diverted, snowflake, droplet — that classical controllers struggle with. This collapses the controller-tuning problem from human-months per shape to GPU-hours per shape. The next reactor OS layer is being written in PyTorch.2022 年 DeepMind 与 EPFL/SPC 证明:一个强化学习策略可控制 TCV 的磁致动器,把等离子体塑造成传统控制器难以驾驭的偏滤、雪花、液滴等形状。控制器调参问题由「每形状数人月」坍缩为「每形状数 GPU 小时」。下一层反应堆 OS 正在 PyTorch 里写。
Why HTS magnets changed everything为什么 HTS 磁体改变了一切
Tokamak fusion power scales as B⁴ × R³. The cost scales like R³. So smaller, higher-field machines win — IF the magnets exist. REBCO high-temperature superconductor tape can carry 20+ tesla at ~20 K, twice what NbTi-based ITER magnets achieve. CFS's 2021 demo of a 20-T HTS coil is what made compact tokamaks venture-fundable.托卡马克聚变功率正比于 B⁴ × R³,造价约正比于 R³。于是更小、更高场的机器更有竞争力——前提是磁体存在。REBCO 高温超导带可在约 20 K 下承载 20+ 特斯拉,是 ITER NbTi 磁体的两倍。CFS 2021 年 20 T HTS 线圈演示,让紧凑托卡马克具备风投可融资性。

Set a doubling time. Set a learning rate. Find the year fusion eats the grid. The model is illustrative — but the shape is what matters.设定翻倍周期与学习率,找出聚变吞下电网的那一年。模型只示意——但形状才是关键。
Solar PV's 50-year learning rate is ~20% per doubling. Wind is ~12%. Nuclear fission, by contrast, has a negative learning rate. Fusion's number is unknown — assume it lies somewhere between solar and the worst nuclear reactor build-out.太阳能光伏 50 年学习率约 20% / 翻倍,风电约 12%, 核裂变反而出现负学习率。聚变学习率仍未知—— 在太阳能与最差的核电建造之间任你押注。
At a 3.5-yr doubling time and 18% learning rate, fusion goes from curiosity to majority-share grid in roughly 60 years from first commercial plant — a faster transition than coal-to-gas, slower than mobile phones. Kardashev I requires civilization-wide 10¹⁶ W, dominating any single energy source — fusion is necessary, not sufficient.若装机翻倍周期 3.5 年、学习率 18%,聚变将在首座商业电站后约 60 年内 从奇观变为电网主力——比煤改气快,比移动电话慢。 卡尔达肖夫一型要求文明级10¹⁶ 瓦,超出任何单一能源—— 聚变是必要条件,不是充分条件。
