摘　　要：Hybrid聚束器是一种同时包含驻波和行波电磁场的新型聚束器。为对其电场分布进行测量,针对此种复杂电场分布的特点,基于非谐振微扰原理,研制了一套能够灵活简便操作、具有较高精度的场分布测量平台,并使用该平台对Hybrid聚束器进行了场分布测量和调配。最终,经过多次测量与调配,Hybrid聚束器的实际冷测微波性能与模拟计算结果符合较好,轴向电场幅值平坦度显著提高,各加速单元间的腔间相移明显改善,使其满足设计要求。The resonant perturbation method can only be applied for the measurement of the standing wave RF field, while the non-resonant perturbation method works for both the standing wave and the traveling wave RF fields. In the hybrid buncher, both the standing wave and the travelling wave RF fields exist. In this scenario, only the non-resonant perturbation method can be adopted. A set of electromagnetic field distribution measurement platform was developed and used for the field distribution measurement and tuning of the hybrid buncher. After several iterations, the measured RF performance of the hybrid buncher was in good agreement with the simulated result.
