论文摘要
可以利用在融合反应器中产生的融合出生的α颗粒的梯度来放大波，从而使α颗粒冷却，同时从反应器中扩散地提取它们。已经建议将谐振α颗粒电荷的相应提取作为驱动旋转的机制。通过得出α通道的耦合线性质量线性理论，我们表明，对于具有纯poloidal波形向量的时间生长波，非均匀离子中的电流取消了谐振α粒子电流，从而阻止了旋转，从而驱动了融合反应。
The gradient of fusion-born alpha particles that arises in a fusion reactor can be exploited to amplify waves, which cool the alpha particles while diffusively extracting them from the reactor. The corresponding extraction of the resonant alpha particle charge has been suggested as a mechanism to drive rotation. By deriving a coupled linear-quasilinear theory of alpha channeling, we show that, for a time-growing wave with a purely poloidal wavevector, a current in the nonresonant ions cancels the resonant alpha particle current, preventing the rotation drive but fueling the fusion reaction.
