摘要

我们报告了一系列的测量横向尾流场从锥形准直器。准直器的设计主要是为了呈现光束的几何阻抗，并尽量减少电阻率或表面特征的阻抗;此外，还选择了准直器的几何形状，以允许检查由于准直器锥度角和最小间隙尺寸而导致的Wakefield的缩放行为。我们给出了准直器近中心尾流场的测量结果，以及束长变化的影响。测量结果与分析模型和MAFIA模拟结果进行了比较。

Transverse wakefields from tapered collimators: measurements and analysis

We report on a series of measurements of the transverse wakefield from tapered collimators. The collimators were designed to principally present a geometric impedance to the beam, and to minimize impedances from resistivity or surface features; in addition, the geometries of the collimators were selected to permit examination of the scaling behavior of the wakefield due to collimator taper angle and minimum gap size. We present the measured near-center wakefields of the collimators, as well as the effect of bunch-length variation. The measurements are compared to analytic models and MAFIA simulations.
