旋转等离子体中的自然热离子模

Natural Hot Ion Modes in a Rotating Plasma

摘要:

在稳态下,聚变等离子体的燃料循环需要燃料离子的向内粒子通量。这些粒子流也伴随着加热。在旋转圆柱形等离子体中的经典输运的情况下,这种加热可以通过几个不同的通道进行,这取决于所涉及的物理机制。一些通道直接加热燃料离子本身,而另一些通道加热电子。一般来说,哪个通道占主导地位取决于等离子体成分的温度、密度和旋转轮廓的细节。然而,值得注意的是,在相对较少的假设下,如果α粒子,聚变反应的副产品,可以通过其他方式直接去除,热离子模式往往会自然出现。

英文摘要:

In steady state, the fuel cycle of a fusion plasma requires inward particle fluxes of fuel ions. These particle flows are also accompanied by heating. In the case of classical transport in a rotating cylindrical plasma, this heating can proceed through several distinct channels depending on the physical mechanisms involved. Some channels directly heat the fuel ions themselves, whereas others heat electrons. Which channel dominates depends, in general, on the details of the temperature, density, and rotation profiles of the plasma constituents. However, remarkably, under relatively few assumptions concerning these profiles, if the alpha particles, the byproducts of the fusion reaction, can be removed directly by other means, a hot-ion mode tends to emerge naturally.
