In this project we are developing an H(-) source which will synthesize the most important developments in the field of negative ion sources to provide high current, high brightness, good lifetime, high reliability, and high power efficiency. We describe two planned modifications to the present spallation neutron source external antenna source in order to increase the plasma density near the output aperture: (1) replacing the present 2 MHz plasma-forming solenoid antenna with a 13 MHz saddle-type antenna and (2) replacing the permanent multicusp magnetic system with a weaker electromagnet.
在本项目中,我们正在开发一种H(-)源,它将综合负离子源领域最重要的进展,以提供高电流、高亮度、长寿命、高可靠性和高功率效率。我们描述了对当前散裂中子源外部天线源的两项计划改进,以提高输出孔径附近的等离子体密度:(1)用13MHz鞍型天线取代当前的2MHz等离子体形成螺线管天线;(2)用较弱的电磁铁取代永久多尖磁体系统。
