摘要

产生强烈的高电荷离子束对大功率重离子加速器至关重要。为超导高电荷态电子回旋共振离子源设计的新型可移动弗拉索夫发射器，在产生高电荷离子束方面可将微波功率效率提高约 4 倍。这种基于专用微波发射系统而非传统耦合方案的方法，使人们对微波与等离子体的相互作用有了新的认识。有了这种新的认识，创世界纪录的高电荷氙离子束电流被提高了 2 倍，这可以直接显著地提高重离子加速器的性能，并为核物理、原子物理和其他学科提供了许多新的研究机会。

Demonstration of high-efficiency microwave heating producing record highly charged xenon ion beams with superconducting electron cyclotron resonance ion sources

Intense highly charged ion beam production is essential for high-power heavy ion accelerators. A novel movable Vlasov launcher for superconducting high charge state electron cyclotron resonance ion source has been devised that can affect the microwave power effectiveness by a factor of about 4 in terms of highly charged ion beam production. This approach based on a dedicated microwave launching system instead of the traditional coupling scheme has led to new insight on microwave-plasma interaction. With this new understanding, the world record highly charged xenon ion beam currents have been enhanced by up to a factor of 2, which could directly and significantly enhance the performance of heavy ion accelerators and provide many new research opportunities in nuclear physics, atomic physics, and other disciplines.
