Field distribution measurement and tuning of the hybrid buncher

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.
