State of the Art ECR Ion Sources

PDF Version Also Available for Download.

Description

Electron Cyclotron Resonance (ECR) ion source which produces highly-charged ions is used in heavy ion accelerators worldwide. Applications also found in atomic physics research and industry ion implantation. ECR ion source performance continues to improve, especially in the last few years with new techniques, such as multiple-frequency plasma heating and better methods to provide extra cold electrons, combined with higher magnetic mirror fields. So far more than 1 emA of multiply-charged ions such as He{sup 2+} and O{sup 6+}, and 30 e{mu}A of Au{sup 32+}, 1.1 e{mu}A of {sup 238}U{sup 48+}, and epA currents of very high charge states such ... continued below
