用千兆伏超级马克思generator点燃氘微爆轰
Ignition of a deuterium micro-detonation with a gigavolt super marx generator
摘要:
Centurion-Halite实验证明了能量不超过几兆焦耳的氘-氚微爆炸的可行性,而Mike试验证明了能量超过10^6兆焦耳的纯氘爆炸的可行性。在这两种情况下,点火能量都是由裂变炸弹炸药提供的。虽然激光和强粒子束可以提供几兆焦耳的能量,在不到10^-9秒的时间内释放出来,但这不足以引发纯氘爆炸。由于氘-氚反应取决于锂的可用性,因此纯氘聚变反应的非聚变点火将是高度期望的。它表明,这一目标可以想象地达到与“超级马克思发电机”,其中大量的“普通”马克思发电机充电(磁绝缘)快速高压电容器的第二阶段马克思发电机,称为“超级马克思发电机”,最终达到千兆伏的潜力与100兆焦耳的能量输出。从“超级马克思发生器”引出的10^7安培-GeV强质子束可以在压缩的氘圆筒中点燃氘热核爆炸波,质子束的强磁场将带电的聚变反应产物捕获在圆筒内。在解决对峙问题时,GeV质子束的刚度允许将氘靶放置在离限制氘微爆炸的腔壁相对较大的距离处。
英文摘要:
The Centurion-Halite experiment demonstrated the feasibility of igniting a deuterium-tritium micro-explosion with an energy of not more than a few megajoule, and the Mike test, the feasibility of a pure deuterium explosion with an energy of more than 10^6 megajoule. In both cases the ignition energy was supplied by a fission bomb explosive. While an energy of a few megajoule, to be released in the time required of less than 10^-9 sec, can be supplied by lasers and intense particle beams, this is not enough to ignite a pure deuterium explosion. Because the deuterium-tritium reaction depends on the availability of lithium, the non-fusion ignition of a pure deuterium fusion reaction would be highly desirable. It is shown that this goal can conceivably be reached with a "Super Marx Generator", where a large number of "ordinary" Marx generators charge (magnetically insulated) fast high voltage capacitors of a second stage Marx generator, called a "Super Marx Generator", ultimately reaching gigavolt potentials with an energy output of 100 megajoule. An intense 10^7 Ampere-GeV proton beam drawn from a "Super Marx Generator" can ignite a deuterium thermonuclear detonation wave in a compressed deuterium cylinder, where the strong magnetic field of the proton beam entraps the charged fusion reaction products inside the cylinder. In solving the stand-off problem, the stiffness of a GeV proton beam permits to place the deuterium target at a comparatively large distance from the wall of a cavity confining the deuterium micro-explosion.
