Design Study of a Higher-magnetic-field Sc Ecris at Imp
نویسندگان
چکیده
Development of ECR ion source has demonstrated that, as the empirical scaling laws summarized, higher magnetic field with higher operation frequency will greatly improve the source performance. Based on the great success of SECRAL at IMP, a higher-magnetic-field SC ECRIS is planned to meet the new accelerator demands. However, there are many practical issues in the design and construction of a higher-field SC ECRIS which need addressed. In this paper we will present and discuss the design features of the higher-field SC ECR with a maximum axial field of 7.0 T and a radial field of 3.5 T at the plasma chamber wall of ID 110 mm, and operating frequency up to 50 GHz.

Gyrotron frequency ECRIS development and the future challenges
Gyrotron frequency amplifier has been used for the production of highly charged ion beams with high performance ECR ion sources (ECRIS) for almost 20 years. The widely used technology of microwave power coupling to the high temperature ECR plasma is still a borrowed design from the fusion machines. ECR ion source technologies and physics are advancing over the years, but the interpretation of h...
متن کاملCusped Mirror Magnetic Field for Electron Cyclotron Resonance Heavy Ion Source
Sufficient beams of Highly Charged Heavy Ions (HCHI) have been obtained in conventional electron cyclotron resonance ion sources (ECRIS) but at the cost of simplicity and economy. A cusped magnetic field (CMF) has more plasma-confining feature but a little current of HCHI’s was extracted from ECRIS using it. The CMF has been reconfigured adopting a simple, novel and cost-effective technique. It...

The main limitation to further improve the performance of ECR ion sources is set by the magnet technology related to the multipole magnet field used for the closed minimum-B structure. The JYFL ion source group has sought different approaches to improve the strength of the minimum-B structure required for the production of highly charged ion beams. It was found out that such a configuration can...
متن کاملSuperconducting Ecr Ion Sources: High Intensity Beams Extraction and Transport
In the last decade a relevant step forward in the design of Electron Cyclotron Resonance Ion Sources (ECRIS) have been obtained and some high performance sources have been built, at the operating frequency of 14,18 and 28 GHz. In particular, the total extracted current exceeds 5 mA in cw mode for some of them, at voltage between 10 and 40 kV. A potential drawback of such intense beams consists ...
