BEPCⅡ直线加速器中的束流轨道和能量稳定性的研究(英文)

Studies on the Beam Orbit and Energy Instabilities at the BEPCⅡLinac

在BEPCⅡ直线加速器的调试和初期运行中,观察到束流轨道和能量的不稳定性.本文通过实验测量和分析研究,说明了这些不稳定性的原因,并叙述了解决这些不稳定性的方法和改进结果.

During the commissioning and early operation of the upgraded BEPC Ⅱ injector linac, some beam instabilities were appeared, and have been studied by both experimental and analytical ways. This paper describes the observed beam orbit instabilities, beam energy jitter, and the beam emittance jitter. The ways to cure these instabilities are also presented.
