The Effect of Ion Flow Сharge Exchange on the Potential Profile in the Expander of an Open Trap
摘要
Abstract
The paper examines the distribution of potential between the magnetic mirror and the plasma flow absorber in an open trap expander. The effect of ion flow velocity variation behind the mirror on the plasma potential is analyzed. The acceleration of the ion flow by the ambipolar electric field is considered. The influence of the ion flow deceleration on the potential distribution due to residual gas charge exchange is discussed.
