Beam Extraction Results with KAERI 14.5 GHz ECR Ion Source | |
|
||
| A 14.5 GHz electron cyclotron resonance ion source has been designed and fabricated at KAERI (Korea Atomic Energy Research Institute) to produce multi-charged ion beams (particularly C6+ ion beams) for medical applications. During the first beam extraction experiments with the developed ion source, it was found that C4+ beam of 15 eμA and Ar15+ beam of 1 eμA were the optimized beam current. A big current loss was made along the beam transport path from the ion source to the entrance port of an analyzing magnet because of long beam line and small acceptance of the magnet. A new Einzel lens is added in the beam line to minimize the beam loss, and the second beam extraction experiments have been made. In this paper the beam experimental results with the KAERI ion source, including the hard X-ray spectrum from the ECR plasma and the emittance measurement results of carbon beam, will be discussed. | ||
