The mechanism that the author’s recently developed for plasma fusion at kiloelectron volts (keV) has been extended from the D-3He fusion with extremely heated 3He ions to the D-T fusion with extremely heated tritons. Two major significances of this extension are that the D-T fusion has the highest reactivity and the plasma does not need H ions, which do not participate in the fusion, because the plasma needs only to generate current-driven electrostatic D-cyclotron (CDEDC) waves for the extra heating of tritons rather than current-driven electrostatic H-cyclotron (CDEHC) waves for the extra heating of 3He ions. The extended mechanism works in a two-stage heating process when an electric current is driven through plasma that contains deuterons and tritons. First, the current ohmically heats the plasma up to some keV, at which the resistivity in the plasma is too low for the current to be significantly dissipated further. When the electric current is continuously driven up to a critical point, however, CDEDC waves are excited, which can preferentially heat tritons via the second-harmonic resonance further to tens of keV or higher, at which the nuclear fusion between the extremely heated tritons and the relatively cold deuterons occurs. In addition, this mechanism can greatly reduce technology and engineering difficulties in plasma control and confinement. This article also develops a new anisotropic model for plasma heating by ion-cyclotron waves and indicates that ions are mainly heated perpendicularly via the cyclotron resonances, while electrons are mainly heated in parallel via the Landau resonance.

氘核在千电子伏特与极端加热的氚核的等离子体聚变

作者最近开发的用于千电子伏 (keV) 等离子体聚变的机制已经从具有极度加热的 3He 离子的 D-3He 聚变扩展到具有极度加热的氚核的 DT 聚变。这个扩展的两个主要意义是 DT 聚变具有最高的反应性，等离子体不需要 H 离子，H 离子不参与聚变，因为等离子体只需要产生电流驱动的静电 D 回旋 (CDEDC) 波用于额外加热氚而不是用于额外加热 3He 离子的电流驱动静电 H 回旋加速器 (CDEHC) 波。当电流通过包含氘核和氚核的等离子体驱动时，扩展机制在两阶段加热过程中工作。首先，电流将等离子体电阻加热到一定的 keV，在这种情况下，等离子体中的电阻率太低，无法进一步显着耗散电流。然而，当电流被持续驱动到临界点时，CDEDC 波被激发，它可以优先通过二次谐波共振将氚加热到几十 keV 或更高，在这个温度下，极度加热的氚和出现相对冷的氘核。此外，这种机制可以大大降低等离子体控制和约束的技术和工程难度。本文还开发了一种新的离子回旋波加热等离子体的各向异性模型，并表明离子主要通过回旋共振被垂直加热，而电子主要通过朗道共振被平行加热。
