利用一种新型的紧凑型磁镜陷阱，证明了2×107个电子在简单磁镜中的约束时间可长于40ms，并且采用多环电极结构可以检测到等离子体的静电振荡。此外，对于镜面受限的非中性电子等离子体，激发并探测到了孤立波。所获得的结果表明，新的紧凑磁镜陷阱将使实验研究电子-正电子等离子体成为可能，而这是迄今为止从未进行过的。
With a new compact magnetic mirror trap, it was demonstrated that the confinement time of 2× 10 7 electrons in a simple magnetic mirror can be longer than 40 ms and that electrostatic oscillations of the plasma can be detected with a multiring electrode configuration. Also, a solitary wave was excited and detected for a mirror-confined nonneutral electron plasma. Obtained results suggest that the new compact magnetic mirror trap will make it possible to investigate electron–positron plasmas experimentally, which have never been conducted so far.
