在FIX机器上进行了场反转配置（FRC）等离子体的平移实验[Shiokawa and Goto， Phys]。[j].中国生物医学工程学报，2004,(5)。平移后的FRC在约束区两端的磁镜场之间反弹。等离子体在被磁场反射时失去部分轴向动能，最终在约束区内稳定下来。在这个反射过程中，等离子体温度明显升高。这种等离子体再热化已经在OCT‐L1实验中被观察到[Ito等人，物理学家]。[j] et al.，物理学报（英文版），1998(1)。流体29,852(1986)]。结果表明，再热化过程取决于等离子体温度与平移速度之间的关系。再热化只发生在平移速度超过声速的情况下。这一结果表明，当等离子体被等离子体反射时，FRC内产生的激波引起了再热化。
A translation experiment of field‐reversed configuration (FRC) plasma is performed on the FIX machine [Shiokawa and Goto, Phys. Fluids B 5, 534 (1993)]. The translated FRC bounces between magnetic mirror fields at both ends of a confinement region. The plasma loses some of its axial kinetic energy when it is reflected by the magnetic mirror field, and eventually settles down in the confinement region. In this reflection process, the plasma temperature rises significantly. Such plasma rethermalization has been observed in OCT‐L1 experiments [Ito et al., Phys. Fluids 30, 168 (1987)], but rarely in FRX‐C/T experiments [Rej et al., Phys. Fluids 29, 852 (1986)]. It is found that the rethermalization depends on the relation between the plasma temperature and the translation velocity. The rethermalization occurs only in the case where the translation velocity exceeds the sound velocity. This result implies the rethermalization is caused by a shock wave induced within the FRC when the plasma is reflected by the m...
