本文介绍了在GOL-3装置上的最新实验结果。在该装置的当前配置中，密度为1014[除以]1016 cm-3的等离子体被限制在12米长的螺线管中，该螺线管包括55个反射镜比Bmax/Bmin=4.8/3.2 T的反射镜单元。螺线管中的等离子体被高功率相对论电子束（~ 1 MeV，~ 30 kA，~ 80 μs，~ 120 kJ）加热到2- 4keV的温度。实验观察到的快速离子加热的机制，等离子体的稳定性和约束的问题进行了讨论。
Recent results of the experiments at GOL-3 facility are presented. In present configuration of the device, plasma with a density of 1014[divided by]1016 cm-3 is confined in a 12-meter-long solenoid, which comprises 55 corrugation cells with mirror ratio Bmax/Bmin=4.8/3.2 T. The plasma in the solenoid is heated up to 2-4 keV temperature by a high power relativistic electron beam (˜1 MeV, ˜30 kA, ˜8 μs, ˜120 kJ) injected through one of the ends. Mechanism of experimentally observed fast ion heating, issues of plasma stability and confinement are discussed.
