Abstract

A novel compact extraction system has been developed at CERN to optimize high-current linacs for medical and industrial use. Replacing the traditional LEBT with a 2 cm-long electrode-based design, it enables efficient proton extraction and acceleration to 45 keV. Tested at the Linac4 test stand, both experimental and simulation results confirm its ability to match to the RFQ acceptance with improved beam quality and reduced footprint, offering a viable solution for next-generation compact linacs.

设计和验证一个紧凑的提取和匹配系统的大电流应用

欧洲核子研究中心开发了一种新型紧凑的萃取系统，以优化医疗和工业用途的大电流直线机。它以2厘米长的电极设计取代了传统的LEBT，实现了高效的质子提取和45 keV的加速。在Linac4测试台上进行了测试，实验和仿真结果都证实了它能够通过提高光束质量和减少占地面积来匹配RFQ验收，为下一代紧凑型直线加速器提供了可行的解决方案。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
