论文摘要
在本文中，我们详细介绍了四极杆成分在射频（RF）光预感染器中的影响，该射频可能会在RF腔或枪螺线管中发生，以及使用偏斜的四极杆校正器进行补偿。该分析被推广到无法在与四极杆同一位置应用校正的情况。讨论了设置校正器以消除X-Y空间中相关性的实用指南。提出了在UCLA Pegasus Phothjector获得的颗粒跟踪模拟和散发体和束矩阵元件的测量值，以验证分析。
In this paper, we present a detailed analysis of the effects of quadrupole components in radiofrequency (RF) photoinjectors, which could occur either in the RF cavity or in the gun solenoid, and their compensation using a skew quadrupole corrector. The analysis is generalized to the case in which the correction cannot be applied at the same location as the quadrupole. A practical guide to setting the corrector to eliminate correlation in the x-y space is discussed. Particle tracking simulations and measurements of emittance and beam matrix elements obtained at the UCLA Pegasus photoinjector are presented to validate the analysis.
