Nuclear fusion promises a nearly limitless energy source, but achieving breakeven-where fusion output exceeds input-requires extreme plasma conditions and complex confinement systems. Here we propose an alternative approach based on beam-target interactions, introducing a simple energy-based criterion that compares fusion energy generation with energy loss. By creating electron-free targets, stopping power is drastically reduced, enabling conditions where fusion energy surpasses beam energy deposition under practical scenarios. This approach offers a viable alternative pathway to fusion energy without high-temperature plasma confinement and warrants further experimental investigation.
Nuclear Fusion in Laser-Driven Counter-Streaming Collisionless Plasmas
核聚变反应是自然界中为恒星提供动力和产生新元素的最重要过程，也是理解宇宙核合成的核心。研究接近真实天体物理条件的全等离子体环境中的反应至关重要。利用激光驱动的逆流无碰撞等离子体，在27 keV的类伽莫夫窗口中研究了D-$+$-D-$\rightarrow n +^3$-He聚变.结果表明，天体物理核反应产额可以通过自生电磁场和等离子体的集体运动来调制。这种等离子体型小型对撞机为在地球实验室中研究天体物理学感兴趣的能量可调的等离子体核反应提供了一种新的工具。
Constraining the equation of state of nuclear matter from competition of fusion and quasi-fission in the reactions leading to production of the superheavy elements
构成晶格的原子核以非常低的能量相对于彼此振荡，该能量不足以穿透将它们分开的库仑势垒。隧穿势垒和熔丝所需的额外能量可以由外部电磁波（X射线或同步辐射）提供。将固体化合物LiD（氘化锂）暴露在X射线下111小时，我们探测到88次d+ Li ~ 6-> Be ~ 8 ~* 核聚变事件。我们的理论估计与我们观察到的一致。我们发现的这种现象的一个可能的应用是测量各种核反应（不一定是聚变）在极低能量下的速率，这在加速器实验中是无法实现的。
