摘要
A small multicusp ion source has been used to generate beams of nitrogen ions. To achieve a high percentage of N+ ions, the source was equipped with a magnetic filter and operated with a high N2 gas density. A nearly pure atomic nitrogen ion (N+) beam (98.5% N +, 1.5% N2+), suitable for implantation purposes, was produced. The operating characteristics of this source, including species mix, are presented.
