高能强流电子束的可靠加速

Towards Reliable Acceleration of High-energy and High-intensity Electron Beams

K. Furukawa, Linac Commissioning Group

摘要:

KEK电子直线加速器升级到8 GeV,用于KEK B工厂(KEKB)项目。在升级后的直线加速器的调试过程中,即使继续SOR环注入,我们也实现了每束10 nC(6.24 x 10^10)的初级电子束,达到了3.7 GeV的正电子产生。这可以被归类为最亮的S波段直线加速器之一。KEKB环自1998年12月建成以来,3.5GeV和8GeV电子束注入性能良好。此外,我们已经成功地在KEKB的高强度光束和两个SOR环的光束之间切换,具有足够的再现性。在KEKB环开始调试后,我们启动了一个项目,以进一步稳定强流束的强度和质量,并完成了对每一个可能的方面的调查。

英文摘要:

KEK electron linac was upgraded to 8 GeV for the KEK B-Factory (KEKB) project. During the commissioning of the upgraded linac, even continuing SOR ring injections, we had achieved a primary electron beam with 10-nC (6.24 x 10^10) per bunch up to 3.7-GeV for positron generation. This could be classified as one of the brightest S-band linac's. Since the KEKB rings were completed in December 1998, those 3.5-GeV position and 8-GeV electron beams have been injected with an excellent performance. Moreover, we have succeeded in switching among the high-intensity beams for KEKB and beams for two SOR rings with sufficient reproducibility. After the commissioning of the KEKB ring started, we have launched a project to stabilize the intensity and quality of the high-current beams furthermore, and have accomplished it investigating every conceivable aspect.
