在康奈尔电子存储环测试加速器 (CesrTA) 上对各种束流能量、束团电荷和束团序列配置下的电子束和正电子束进行了相干调谐偏移测量。将观察到的曲调与几个电子云模拟程序的预测进行比较，可以评估这些模型中的重要参数。这些模拟将用于预测未来线性对撞机阻尼环中电子云的行为。我们概述了分析技术的最新改进，这些改进应该可以提高建模的保真度。
Measurements of coherent tune shifts at the Cornell Electron Storage Ring Test Accelerator (CesrTA) have been made for electron and positron beams under a wide variety of beam energies, bunch charge, and bunch train configurations. Comparing the observed tunes with the predictions of several electron cloud simulation programs allows the evaluation of important parameters in these models. These simulations will be used to predict the behavior of the electron cloud in damping rings for future linear colliders. We outline recent improvements to the analysis techniques that should improve the fidelity of the modeling.
