论文摘要
PIP II线性加速器包括不同类型的Niobium SRF腔，包括650 MHz椭圆形低（0.61）和高（0.92）β型腔。椭圆形表面通过电抛光方法处理。椭圆形腔，尤其是低$β$ 650 MHz的腔体显示EP按照标准EP条件为单位后的粗糙赤道表面。这项工作集中在研究不同的EP参数（包括阴极表面积，温度和电压）的效果，并优化它们以改善空腔表面。
The PIP II linear accelerator includes different types of niobium SRF cavities including 650 MHz elliptical low (0.61) and high (0.92) beta cavities. The elliptical cavity surface is processed with the electropolishing method. The elliptical cavities especially the low-$β$ 650 MHz cavities showed a rough equator surface after the EP was per-formed with the standard EP conditions. This work was focused to study the effect of different EP parameters, including cathode surface area, temperature and voltage, and optimize them to improve the cavity surface.
