离子源是强流质子回旋加速器的核心设备之一,它的性能直接影响着最终束流强度大小和品质。本文介绍用于强流质子回旋加速器上的多峰场负氢离子源的实验研究结果,该离子源是通过深入研究对束流强度、品质影响的几个关键因素并加以优化,引出的H-离子束达18mA。1提高H-束流流强1.1引出电压-H-束流强
The ion source is one of the core devices of the high-flux proton cyclotron and its performance directly affects the intensity and quality of the final beam. In this paper, the experimental results of multi-peak negative hydrogen ion source for intense proton cyclotron are introduced. The ion source is studied and optimized by further study on the influence of beam intensity and quality. The H- Ion beam up to 18mA. 1 to improve the H-beam current intensity 1.1 leads to the voltage-H-beam intensity
