| 摘 要： | An electron Penning-Malmberg trap,which can confine an electron column and provide a good platform to investigate the cross-filed transportation of strongly magnetized electron plasma ,has been set up.With the device,an electron plasma with a density of 10^7 cm^-3 can be confined for a relatively long time.The structure of the trap,electron source,as well as the way how th measure electron plasma density profile and velocity distrbustion are introduced in detail.

| Abstract: | An electron Penning-Malmberg trap, which can confine an electron column and provide a good platform to investigate the cross-field transportation of a strongly magnetized electron plasma, has been set up. With the device, an electron plasma with a density of 107 cm-3 can be confined for a relatively long time. The structure of the trap, electron source, as well as the way how to measure electron plasma density profile and velocity distribution are introduced in detail. |
