报道了首次利用亚聚变等离子体参数测量镜阱扩展器中的等离子体参数。膨胀器端板附近的电位降似乎比陷阱中心的电子温度低得多。在膨胀器区域中的电子的特征能量也基本上低于约束等离子体中的电子温度。磁场膨胀比K在30 ~ 160之间变化不影响约束等离子体的主要参数。在K = 30时，约束等离子体的电子温度约为700 eV。
First measurements of plasma parameters in an expander of a mirror trap with sub-fusion plasma parameters are reported. Potential drop near the end plates of the expander appears to be much lower than the electron temperature in the center of the trap. Characteristic energy of electrons in the expander region is also substantially lower than the electron temperature in the confinement plasma. Variation of the magnetic field expansion ratio K between 30 and 160 does not influence the main parameters of the confinement plasma. Electron temperatures of the confinement plasma of about 700 eV were achieved at K = 30.
