标题： Hypervelocity Impact Fusion with Compressed Deuterium-Tritium Targets

摘要： 在惯性约束聚变实验中，对于更高的压缩比，观测到的中子产率比一维模型预测的中子产率小约两个数量级，这种差异归因于不稳定性的发展。 我们认为，如果现有的激光设施将激光驱动能量用于仅产生燃料胶囊的径向压缩以达到高密度但相对较低的温度，那么点火和适度增益可能得以实现，而压缩燃料胶囊中的聚变反应点火将通过同步超高速撞击来实现。 如果使用长度为13公里的常规低β直线加速器，可以将带正电的入射粒子加速到3.5 x 10^6 m/s的速度，从而产生约4 keV的点火温度，前提是可以通过激光驱动压缩获得570 g/cm^3的氘氚密度。 显示英文摘要

摘要： The neutron yields observed in inertial confinement fusion experiments for higher convergence ratios are about two orders of magnitude smaller than the neutron yields predicted by one-dimensional models, the discrepancy being attributed to the development of instabilities. We consider the possibility that ignition and a moderate gain could be achieved with existing laser facilities if the laser driver energy is used to produce only the radial compression of the fuel capsule to high densities but relatively low temperatures, while the ignition of the fusion reactions in the compressed fuel capsule will be effected by a synchronized hypervelocity impact. A positively-charged incident projectile can be accelerated to velocities of 3.5 x 10^6 m/s, resulting in ignition temperatures of about 4 keV, by a conventional low-beta linac having a length of 13 km if deuterium-tritium densities of 570 g/cm^3 could be obtained by laser-driven compression.
