Assisted by the bead pull technique, nonresonant perturbation theory is applied for measuring and tuning the field of the linac accelerating structure. The method is capable of making non-touching amplitude and phase measurements, real time mismatch feedback and field tuning. Some key considerations of the measurement system and of a C-band traveling-wave structure are discussed, and the bead pull measurement and the tuning of the C-band traveling-wave linac accelerating structure are presented at last.
