Abstract
Removal of plasma in a gadolinium atomic beam was tried under high-rate evaporation using an axial electron gun. Positive or negative electric potential was applied to removal electrodes which were a pair of parallel electrodes put along the atomic beam. When positive potential was applied to the removal electrodes, current of several amperes flowed into the electrodes and the plasma could not be removed because arc current flows from high temperature evaporation surface to the removal electrodes. On the other hand, the removal of the plasma was achieved by applying high negative potential to the removal electrodes. The plasma flowing up with the atomic beam had grounded potential and ions were extracted to the negatively biased removal electrodes from the plasma. The removal electrode potential to extinguish the plasma between the electrode was estimated using the plasma parameters such as density, electron temperature, and drift velocity. The estimated values agreed well with experimental results. (author).
