摘要

粒子束的稳定性和质量对许多新兴的直线装置至关重要。对于各种加速器子系统中波束电磁元件的错位和抖动/波动对波束性能的影响和损伤应该有充分的了解,因为通常这种弹间波动是无法避免的。最重要的是,了解机器对哪些参数最敏感,采取预防措施以减少光束退化,从而提高光束的稳定性和质量。本文研究了基于射频光注入电子源的50 MeV s波段直线加速器。研究了光束参数对若干误差的敏感性,并对每个加速器元件分别进行了研究。直线加速器末端的发射度主要受加速段的层流行为影响,而直线加速器入口的轨道误差是导致发射度下降的主要原因。

Random error propagation on electron beam dynamics for a 50 MeV S-band linac
The stability and the quality of particle beams are of utmost importance for many emerging linac installations. The impact on beam properties damage of beam electromagnetic element misalignments and jitter/fluctuations in various accelerator sub-systems should be properly known, as usually such shot-to-shot fluctuations cannot be avoided. On top of that, knowing which parameters the machine is most sensitive to is of utmost to take precautionary measures to reduce the beam degradation and thus improve beam stability and quality. This simulation work focuses on a 50 MeV S-band linear accelerator based on RF photoinjector electron source. The sensitivity of the beam parameters towards several errors has been studied collectively as well as individually for each accelerator element. While the emittance at the end of the linac is dominated by the laminar behavior in the accelerating section, the main emittance degradation comes mainly from orbit errors located at the linac entrance.
