提出了等离子体射流驱动磁惯性聚变的半解析模型。计算了磁化等离子体靶与球形内爆等离子体衬层的一维耦合，考虑了衬层材料的可压缩流体力学和电离、传导和辐射引起的能量损失、聚变燃烧和α沉积、靶中离子和电子的温度、磁压力和燃料燃耗。结果表明，当衬层厚度为1 cm，预热磁化靶初始半径为4 cm时，在球收敛比<15，衬层能量为20-40 MJ时，一维增益为3-30。给出了参数空间和物理设置的一些探索。观察到的产量表明，有可能点燃额外的致密燃料层，以达到高增益。
A semi-analytic model for plasma-jet-driven magneto-inertial fusion is presented. Compressions of a magnetized plasma target by a spherically imploding plasma liner are calculated in one dimension (1D), accounting for compressible hydrodynamics and ionization of the liner material, energy losses due to conduction and radiation, fusion burn and alpha deposition, separate ion and electron temperatures in the target, magnetic pressure, and fuel burn-up. Results show 1D gains of 3–30 at spherical convergence ratio <15 and 20–40 MJ of liner energy, for cases in which the liner thickness is 1 cm and the initial radius of a preheated magnetized target is 4 cm. Some exploration of parameter space and physics settings is presented. The yields observed suggest that there is a possibility of igniting additional dense fuel layers to reach high gain.
