摘要

In order to study a new method of generating energetic ion, a linear plasma device NUMBER was designed and constructed. The device consists of a plasma production region and a test region connected axially. The radial profile of the electron density and the electron temperature were measured using a Langmuir probe. The radius of plasma is consistent with a field line trace calculation. The time evolution of the ion saturation current I is was measured. A high I is phase accompanied by rapid increase and rapid decrease of I is was observed. From the scan of magnetic field in the test region, it is found that the high I is phase may be caused by unexpected electron cyclotron resonance in the test region. The gas pressure is also related to the appearance of the high I is phase.
