摘要:
提出了一种新型周期永磁（PPM）聚焦系统，其中，每半个周期的这种PPM聚焦系统由1件极靴和5块永磁体共同组成，第1、第3、第5块永磁体与第2、第4块永磁体的极化方向相反，且任何相距半个周期的2块永磁体均具有相反的极化方向。采用MTSS2018对这种新型PPM聚焦系统的磁场进行了计算，结果表明新型PPM聚焦系统的轴线上磁感应强度Bz具有显著的第3次和第5次空间谐波，在过0点后能够更快上升到峰值，整体构型十分接近具有理想矩形分布的PPM系统。采用MTSS2018对G波段分布作用速调管（EIK）所需的电子枪进行了模拟计算，并采用上面计算的Bz对该电子注进行聚焦，获得了电子注电压为22 kV，电子注电流为215 mA的电子注，电子注最大半径为0.08 mm，满足G波段EIK的应用要求。计算中的峰值磁感应强度仅为1.2\begin{document}$ \sqrt 2 $\end{document} ![]()

摘要:
Magnetized Liner Inertial Fusion (MagLIF) concept has promising potentials for future energy source (Phys.Plasmas, 2014, 21:072711), it is widely applicable to large-scale pulsed power generators such as the Primary Test Stand (PTS) facility (10 MA, 100 ns). In this context, we’ve developed a zero-dimensional (0D) MagLIF simulation code basing on magneto-hydrodynamic (MHD) equations and Deuterium-Tritium (DT) fusion models. Relationships between fusion products and initial setups (magnetic field Bz0, preheat temperature T0 and so on) are explored using this code, results show optimal parameters existing under given inputs, which are very helpful for future experimental designs. Specifically, according to our simulations, critical driving current (＞21.2 MA) is essential for fuel (50∶50 DT) energy to reach breakeven, which infers that PTS facility may not be suitable for integrated MagLIF experiments. Series of calculations are performed to confirm this inference, and more practical aluminum liner experiments are proposed and designed.
