Negative Ion Source and Beam Development at BNL

Ion Beam Cocktail Development and Ecr Ion Source Plasma Physics Experiments at Jyfl*

The accelerator based experiments at JYFL (University of Jyväskylä, Department of Physics) range from basic research in nuclear physics to industrial applications. A substantial share of the beam time hours is allocated for heavy ion beam cocktails, used for irradiation tests of electronics. Producing the required ion beam cocktails has required active development of the JYFL ECR ion sources. T...

Ion Beam Measurements at the Superconducting ECR Ion Source SECRAL

Intense Beam Ion Sources Development at Imp *

To satisfy the HIRFL (Heavy Ion Research Facility in Lanzhou) accelerators’ requirement and the needs of several other future accelerator facilities, many high beam intensity ion sources have been developed at IMP. The ion sources include intense high charge state ion beam ECR ion sources and high intensity proton beam ECR or microwave sources. This paper will review the high charge state ion s...

Ion Source Development at the Agor Facility∗

This paper discusses the present status of ion source development at KVI. Work is mainly focussed on increasing the beam intensity of the ECRIS injector and to optimize the beam transport and injection into the AGOR cyclotron. The ultimate goal is to deliver a 1 kW beam of heavy ions on target. Recent progress towards this goal is discussed. We also present the first results of beam extraction ...

Uniform Negative Ion Beam Extraction in a Cesium-Seeded Large Negative Ion Source with a Tent Magnetic Filter

For improvement of spatial uniformity of negative ion beams, the external magnetic filter was replaced to a novel tent-shaped magnetic filter in the JAEA 10 ampere negative ion source. The tent filter geometry is based on new findings in surface production of negative ions in high electron temperature plasmas. In order to link the tent filter, the original line-cusp field configuration on the s...
